In addition, when having surpassed the benchmark injection rate, promptly ratio P has surpassed at 100% o'clock in the accumulative total injection rate, in order to warn, and for example goes out bar diagram (with reference to figure 5) with red display.In addition, surpassed at 100% o'clock, in injection rate management information picture, demonstrated the amount that surpasses that the accumulative total injection rate surpasses the benchmark injection rate with numerical value at ratio P.And then, surpassed at 100% o'clock at ratio P, in injection rate management information picture, demonstrate and be used to warn the accumulative total injection rate to surpass the warning message (with reference to figure 5) of the situation of benchmark injection rate.
Can at random change the ratio that the display format that is used to make this bar diagram changes by the operator with respect to the benchmark injection rate.Injection rate data storage part 26 is stored the data of accumulative total injection rate and subject information, inspection message simultaneously in the moment that check to finish.
The contrast agent injection rate management activities of present embodiment then, is described.
Actual begin to check before, provide the checking process of planning out data from inspection message memorizer 8 to injection plan parts 39 by inspection program parts 13.The checking process data comprise the order of a plurality of photography steps, the radiography dosage that uses in each photography step.Injection plan parts 39 will be included in the summation of the contrast agent that a plurality of photographies of this checking process use and calculate as the anticipation accumulative total injection rate Ve that uses in this checking process.Injection plan parts 39 will be envisioned accumulative total injection rate Ve and compare with the benchmark injection rate that provides from benchmark injection rate memory unit 23.When anticipation accumulative total injection rate Ve had surpassed the benchmark injection rate, injection plan parts 39 demonstrated on display unit 12 and are used to warn anticipation accumulative total injection rate Ve to surpass the information of the situation of benchmark injection rate.With warning message side by side, the radiography dosage that demonstrates the flow process of checking process, uses in step in each photography.According to the operation of functional unit 34, at random change the radiography dosage (injection rate or injection length) that the step of respectively photographing is used, make anticipation accumulative total injection rate Ve be no more than the benchmark injection rate.After checking beginning, value or its absolute value of the prediction accumulative total injection rate Va ' of the accumulative total injection rate Va that injection plan parts 39 calculate the present moment that calculates at injection rate cumulative calculation parts 25 and the present moment that can find out in advance according to the predetermined injection rate of the step of respectively photographing of checking process poor (Va-Va ').With numerical value the prediction of present moment accumulative total injection rate Va ', poor (Va-Va ') are presented on the display 28.If poor (Va-Va ') big, represent that then the injection rate of contrast agent is more than what be scheduled to, promptly injection rate is too fast.At poor (Va-Va ') when having surpassed setting, on display 28, demonstrate the information that the actual contrast agent injection rate of expression is Duoed than scheduled volume, and make the prediction accumulative total injection rate Va ' of present moment, the display format of poor (Va-Va ') for example change into redness, or be changed to the flicker demonstration simultaneously.To for example be set to the arbitrary proportion of benchmark injection rate Vth with poor (the Va-Va ') setting that compares, for example 10%.
Can at random be provided with and revise this ratio by user and manufacturer side.In addition, inject poor (Va-Va ') of plan parts 39, by (Ve+ (Va-Va ') according to the contrast agent injection rate of reality and scheduled volume) anticipation of revising inspection finish time injection rate Ve totally.With numerical value revised anticipation accumulative total injection rate Ve is presented on the display 28.When revised anticipation accumulative total injection rate Ve has surpassed benchmark injection rate Vth, make the display format of anticipation accumulative total injection rate Ve for example be changed to redness, perhaps be changed to flicker and show.
Fig. 2 represents the step of the contrast agent injection rate management activities of present embodiment.In addition, in this convenience, suppose to inject contrast agent to subject individually from the injection device 36 of contrast agent bottle 37 in order to illustrate.Before checking beginning, contrast medium injection management control assembly 21 is obtained the data (S11) of the benchmark injection rate corresponding with the weight in patients of inspection message from benchmark injection rate memory unit 23.The data of benchmark injection rate are offered injection rate comparing unit 33 and display control unit spare 27.In addition, contrast medium injection management control assembly 21 is obtained the data (S12) of the accumulative total injection rate last time checked relevant with this subject of inspection object from injection rate data storage part 26.The data of the accumulative total injection rate last time checked are offered display control unit spare 27.In addition, control according to contrast medium injection management control assembly 21, provide name, age, sex, the height of the patient information in the inspection message, the data of body weight from inspection message memorizer 8 to display control unit spare 27, and provide the data that add up injection rate from cumulative calculation parts 25, provide the data of accumulative total injection rate with respect to the ratio P of benchmark injection rate from injection rate comparing unit 33.
The data that display control unit spare 27 bases provide are constructed out the contrast agent injection rate supervisory frame data of example shown in Figure 3, and it is presented on the special-purpose display 28 of contrast agent information demonstration (S13).As literal/numerical information, in contrast agent injection rate supervisory frame, comprise name, age, sex, height, body weight, contrast agent and inject the zero hour, the injection total amount of last time checking, benchmark injection rate, accumulative total injection rate.In addition, in contrast agent injection rate supervisory frame, comprise by display control unit spare 27 according to adding up the bar diagram that the ratio P of injection rate with respect to the benchmark injection rate generates.As display format, in this rectangular graph corresponding with the benchmark injection rate by colouring discrimination with the corresponding area portions of this ratio P.In stage before contrast agent injects beginning, ratio P is 0, does not therefore divide the part of color.
After the beginning contrast agent injected, weight sensor control assembly 31 began to measure the weight of contrast agent bottle 37 via weight sensor 32.Cycle with regulation is carried out weight measurement repeatedly, from weight sensor control assembly 31 weight data of output contrast agent bottle 37 repeatedly.From weight sensor control assembly 31 to the contrast agent injection rate one by one calculating unit 24 weight data of contrast agent bottle 37 is provided.Contrast agent injection rate calculating unit 24 one by one obtains last time the difference of the weight of the weight measured and this measurement, in this difference is not 0 o'clock (S14), being judged as weight changes, promptly be carved into when last time measuring this measure constantly between injected contrast agent, according to optionally obtain according to the contrast agent kind of inspection message from specific gravity data memory unit 22 with use corresponding proportion and the weight change of contrast agent, calculate injection rate (volume) Vs (S15).Cumulative calculation parts 25 calculate accumulative total injection rate Va (S16) by to from checking that the injection rate Vs that begins the zero hour adds up.
In addition, when changing contrast agent bottle 37, owing to unload contrast agent bottle 37, so weight can change tempestuously.It is characterized in that a certain amount ofly within a certain period of time, for example 10 seconds with the rapid variation more than the interior 50cc.Detect this rapid variation by calculating unit 24 or 25, be judged as and changed contrast agent bottle 37, and not as the contrast agent injection rate.Contrast agent injection rate calculating unit 24 one by one resets (reset) to gravimetric value in the moment that then weight has increased, and after this monitors the weight that has reduced once more.Certainly, even cumulative calculation parts 25 do not reset to the accumulative total injection rate yet, and continue to use the accumulative total injection rate when having changed contrast agent bottle 37.
Injection rate comparing unit 33 will add up injection rate Va and benchmark injection rate Vth compares (S17).In fact, injection rate comparing unit 33 calculates the ratio P of accumulative total injection rate Va with respect to benchmark injection rate Vth.In addition, injection rate comparing unit 33 by deduct accumulative total injection rate Va from benchmark injection rate Vth, calculate reach can inject till the benchmark injection rate Vth can injection rate.With can injection rate and the data of accumulative total injection rate Va, accumulative total injection rate Va be offered display control unit spare 27 with respect to the data of the comparative result (ratio P) of benchmark injection rate Vth.Display control unit spare 27 constitutes the picture (S18, S19, S20) corresponding with respect to the comparative result of benchmark injection rate Vth with accumulative total injection rate Va.
The display format of injection rate management information picture has 3 kinds of following patterns according to the increase of accumulative total injection rate:
(1) add up 80% o'clock (P≤0.8) of injection rate Va smaller or equal to benchmark injection rate Vth,
(2) accumulative total injection rate Va surpasses 80% of benchmark injection rate Vth, and accumulative total injection rate Va is during smaller or equal to benchmark injection rate Vth (0.8＜P≤1),
When (3) accumulative total injection rate Va surpasses benchmark injection rate Vth (1＜P).
Pattern (1) and common picture corresponding (S18).Pattern (2) corresponding with the picture that arouses attention (S19).Pattern (3) and warning picture corresponding (S20).
In Fig. 3, represented the example of common picture of the pattern of above-mentioned (1).As mentioned above, in contrast agent injection rate supervisory frame, comprise name, age, sex, height, body weight, contrast agent as literal/numerical information and inject the zero hour, the injection total amount of last time checking, benchmark injection rate, accumulative total injection rate, demonstrate the ratio P of accumulative total injection rate with bar diagram in addition with respect to the benchmark injection rate.Demonstrate to the branch color in the Zone Full of bar diagram with the corresponding area portions of this ratio P, therefore can easily grasp the state of present injection rate intuitively.Specifically, bar diagram as reference colours, is used " white " " cyan " performance and the corresponding area portions of this ratio P on this basis.
In Fig. 4, represent the picture that arouses attention of the pattern of above-mentioned (2).When accumulative total injection rate Va had surpassed 80% amount of benchmark injection rate with respect to the ratio P of benchmark injection rate Vth, the color of the area portions of bar diagram was changed to " yellow " from " cyan ".In addition, surpassed at 80% o'clock, in injection rate management information picture, demonstrated and be used for the accumulative total injection rate has been surpassed the information that arouses attention that the situation of 80% amount of benchmark injection rate arouses attention at ratio P.Thus the injection rate of the contrast agent situation near the benchmark injection rate is aroused attention.
In Fig. 5, represent the picture of the pattern of above-mentioned (3).When accumulative total injection rate Va has surpassed benchmark injection rate Vth, in bar diagram, amplify corresponding area portions accordingly with ratio P with accumulative total injection rate Va according to the part corresponding with benchmark injection rate Vth.This, the color of the area portions of bar diagram is changed to " redness " from " yellow ", area portions flicker that simultaneously should redness.In addition, demonstrate by what injection rate comparing unit 33 calculated with numerical value and surpass injection rate.Surpassing injection rate is the amount that accumulative total injection rate Va has surpassed benchmark injection rate Vth.And then, when the accumulative total injection rate has surpassed the benchmark injection rate, show to be used to warn the accumulative total injection rate to surpass the warning message of benchmark injection rate.By the variation of above display format, the situation that the injection rate of contrast agent is surpassed the benchmark injection rate arouses attention consumingly.
In addition, in the present embodiment, promptly do not stop the measure that contrast agent injects yet, or do not show this information that promptly stops of urgency yet even the accumulative total injection rate reaches the benchmark injection rate.Just the situation that the injection rate of contrast agent is surpassed the benchmark injection rate arouses attention consumingly.Its reason is that the benchmark injection rate is set to the low value of threshold value (higher limit on the safety) than health.Thus, before the contrast examination of needs finishes, can avoid the contrast agent injection rate to reach gauge as much as possible and the situation of interrupting.
Till check finishing (S21), for example carry out a succession of processing repeatedly from above-mentioned S14 to S20 with about 0.1 second extremely short specified period.The photography technician can almost grasp the amount that contrast agent injects and the present situation of the ratio of injection in real time, checks on one side can consider the contrast agent injection plan of checking till the end to a certain degree.
After checking end, as the injection rate summation of this inspection, determine final accumulative total injection rate, and store (S22) in the injection rate data component 26 into subject information and inspection message.
As mentioned above,, the management precision of the injection rate of contrast agent can be improved, contrast agent can be in a planned way injected according to present embodiment.Can reduce the injection of useless unwanted contrast agent, and then can avoid owing to injecting the situation that too much contrast agent interrupts checking.
In the above-described embodiments, check according to above-mentioned checking process.But the measurement of accumulative total injection rate has more than and is limited to above-mentioned checking process.
The present invention has more than and is limited to above-mentioned described embodiment, in the scope of aim of the present invention various distortion can be arranged.
