Fig. 4 is the machine drawing of indicating section safety trip.
With reference to Fig. 1, multimode system 10 comprises computed tomography imaging system or first mode 12 and the nuclear imaging system or second mode 14.This computerized tomography (CT) imaging system 12 comprises CT scan machine 16, and this scanner unit comprises a nonrotational frame 18 again.On rotation frame 22, X-ray tube 20 is installed.Patient's receiving orifice of this CT scan machine 16 is stipulated in hole 24.Radiation detector 26 arrays are housed to receive the x-ray radiation of X ray after being horizontally through patient's receiving orifice 24 on rotating frame 22.Another kind of way is detector array to be installed in whole one on the nonrotational frame 18 enclose.
This nuclear imaging system 14 preferably includes positron emission fault (PET) scanner unit 28, and it is installed on the track 30.Certainly, also can adopt SPECT and other nuclear imaging systems.Track 30 extends along patient support or patient's bed 32 y directions, and the tight system that makes CT scan machine 16 and PET scanner unit 28 form both sides' formula maybe can separately be used for the independent operation (not shown).Mobile device 34 as motor and driver, is used for scanner unit 28 separately and moving between the intimate position.The detector (not shown) is 36 arrangements around the hole, and hole 24 alinements of this hole 36 and CT scan machine are to determine patient's receiving orifice of PET scanner unit 28.In this PET system, its detector preferably is arranged in stationary ring, though also can consider to have the situation of rotary head.In the SPECT system, preferably detector is packed in the single head, and being mounted to relative patient, these heads rotate and radial motion.
Continuation is placed in patient on the patient support 32 with reference to Fig. 1, and movable workbench makes patient be in the position of patient's receiving orifice 24 of CT scan machine then, and this position is the CT image space.The electronics data are reconstructed into the three dimensional CT image and are stored in the CT image storage 40 with CT reconstruction processor 38.Then, patient support 32 and patient move into 28 scannings of PET receiving orifice 36 usefulness PET scanner units together and produce 3-D view.The electronics data are reconstructed into the PET image and are stored in the PET image memory 44 with PET reconstruction processor 42.As selection, when the nuclear image reconstruction, can correct because skeleton or compact tissue cause the attenuation effect to ray with the CT image.
Fusion processor or install 46 and receive CT and PET image to be combined into a width of cloth 3-D view.Combination image is stored in the three-dimensional arrangement image storage 48.Video processor 50 extraction data from this three-dimensional arrangement memorizer 48 is also handled to be used for showing at display device 52.
With reference to Fig. 2 A, patient support 32 is shown in leisure or complete retracted position A, and this position is used to load and unload patient.These two supporting bases of patient support 32 usefulness or pillar 60,62 are fixed on the floor, and each pedestal comprises driving mechanism 64,66 respectively, is used for patient support is moved up and down so that load and unload patient.Main support saddle 68 is parallel with the upper surface 70,72 of pillar 60,62 basically.The lower end 74,76 of pillar 60,62 is preferably adopted carefully and is followed closely so that patient support 32 is fixed on the floor.This patient support 32 comprises intermediate pallet 78, and this intermediate pallet is positioned on the upper surface 80 of main support saddle 68.Subject pallet 82 adopts the radiation hardness material to manufacture, and is positioned on the upper surface 84 of intermediate pallet 78.Even the most handy reinforced carbon fiber material of subject pallet is to guarantee also can to avoid deflection or deflection very little to the heaviest patient.Intermediate pallet 78 usefulness static support member 86 and first and second intermediate bearing support member 88,90 support.This static support member 86 is positioned at the master and supports near main forward position 92 lower surfaces with support intermediate pallet 72 that support saddle 68 on the saddle upper surface 80.The first and second intermediate bearing support members 88,90 are positioned on the intermediate pallet lower surface 94.Second intermediate support 90 places the tailing edge 96 of intermediate pallet 78 neighbouring so that intermediate pallet in main saddle upper surface 80 upper supports that support movably.With cantilevered fashion subject pallet 82 is installed on the subject pallet bearing supports 98, this bearing supports 98 is positioned at above near the tailing edge 102 of subject pallet 82 the lower surface 100, is used for mobility and supports subject pallet 82 on the intermediate pallet upper surface 84.Motor 104,106 drives intermediate pallet 78 and subject pallet 82 respectively and disease is manually made platform 32 sends into first and second modes (not shown carry out imaging).
With reference to Fig. 2 B, this moment, patient support 32 was in position B, intermediate pallet 78 and the subject pallet 82 relative main original position (not shown) that saddle 68 all stretches out and arrive first mode slightly that support on this position.The tip 110 of the intermediate pallet 78 in the forward position 112 of contiguous intermediate pallet 78 is supported by static support member 86.Side-play amount between main saddle forward position 92 and the intermediate pallet forward position 112 is used apart from d and is represented that it is the distance from patient support to the first scanner unit at this moment.At position B, its subject pallet 82 is still parallel with ground basically when loading the patient of weight limit.
With reference to Fig. 2 C, this moment, patient support 32 was in position C, and subject pallet 82 stretches into the first mode (not shown) fully on this position.Because intermediate pallet 78 does not move, its tip 110 is still supported by static support member 86, and this is a skew apart from intermediate pallet forward position 112, and its distance is identical as the B of position, for example be shown in Fig. 2 B apart from d, and it is irrelevant to stretch into what of first mode with subject pallet.The subject pallet 82 of stretching out is that the patient support 98 of the end section 114 of contiguous patient support saddle tailing edge 102 supports, and its cantilever degree is identical.Because subject pallet is to support from support member 98 upper cantilevers, B compares with the position, and on the position C that loads patient, subject pallet 82 is deflection more or less.Because this cantilever can't be in first scanner unit because of patient's body different parts and change, so the size of deflection can not change yet.
Refer again to Fig. 2 B and with reference to Fig. 2 D, for imaging in second mode, subject pallet 82 is retracted into position shown in Fig. 2 B.Subject pallet 82 is stretched to the position D of patient support together with intermediate pallet 78 then.Should be noted that patient's load is in the back of intermediate pallet 78 when two saddles are mobile together because disease is manually made platform drive tab 98 between intermediate support block 88 and 90.The load that does not have patient at the front end 110 of intermediate pallet.Patient and intermediate pallet 82 and 78 extend through the first mode (not shown) and arrive the original position (not shown) of second mode.Not significantly skew between the forward position 116 of intermediate pallet forward position 112 and subject pallet 82.Arrestment mechanism 118 supports the intermediate pallet 78 that is in extended position, when stretching out with convenient subject pallet load is placed intermediate pallet tip 110.More particularly, this arrestment mechanism 118 comprises a motor 120, and it drives relevant hoisting mechanism 122 makes arrestment mechanism 118 arrive differing heights position, relative floor.Typically, at position A-C, this arrestment mechanism 118 is in idle condition and keeps the leisure position.When middle saddle 78 stretched out fully, until brake mechanism supporting member 124, this support member 124 was positioned near the forward position 128 of arrestment mechanism 118 upper surfaces 126 motor 120 driving lifting devices 122, contacts with intermediate pallet bottom surface 94 with arrestment mechanism 118 liftings.Intermediate pallet 78 the most handy reinforced carbon fiber material manufacture are parallel with the floor basically with the maintenance intermediate pallet to prevent deflection.
Continuation is with reference to Fig. 2 D and Fig. 2 C, and the skew among the offset d co-located C between arrestment mechanism forward position 128 and the intermediate pallet forward position 112 between main saddle forward position 92 and the intermediate pallet forward position 112 is identical.Adopt this mode, identical in the support of its middle saddle of position C and position D.
With reference to Fig. 2 E and Fig. 3, this moment, patient support 32 was positioned at position E, and subject pallet 82 stretches to second mode 14 fully on this position.Because intermediate pallet 78 does not move, intermediate pallet tip 110 still is subjected to the support of brake mechanism supporting member 124, apart from the side-play amount in intermediate pallet forward position 112 have position B-D with above-mentioned discussion identical apart from d.Therefore, be identical even intermediate pallet receives identical load and has deflection at position C and E.The subject pallet 82 of stretching out is supported with identical cantilevered fashion by the patient support 98 of subject pallet end section 114.Because subject pallet adopts cantilevered to install, which deflection of partly being in its subject pallet in second scanner unit of patient's body can not change.
Continuation is with reference to Fig. 2 E and Fig. 2 C, and in second mode during the imaging, it is identical to load during patient's its size of deflection and the first mode imaging of subject pallet 82 deflection of position C.The constant deflection of subject pallet 82 in dual mode guaranteed between the dual mode registration more reliably, because patient is orientated and has kept unanimity for detector.
For the subject pallet of withdrawing, its process is opposite.In particular, subject pallet moves to position D from position E.Then, two saddles together from position D through position B to position A, A unloads patient in the position.
Continuation is ON with reference to Fig. 3 and Fig. 4 at its power supply of normal work period.For allowing saddle 78 and 82 to move, the solenoid (not shown) by rack shaft 152 relatively spring setover to rotate and locking lever 148 is stretched out sprocket 144 and shaft lever 142 shifted out outside the track of latch 140.Locking lever 148 is stretched out sprocket 144 will make screw mandrel 146 mobile intermediate pallet 78 between position B and D.If subject pallet 82 extends position C and position E, then guarantee that by software intermediate pallet 78 can not be driven.Safe release or retracting device 150 guarantee can not be manually with subject pallet 82 with the order of safety from complete extended position E fast retractile to the position A that lies fallow.Subject pallet 82 is withdrawn fully before intermediate pallet 78 withdrawals, and this point will be discussed below in further detail.During 14 imagings of second mode, for example at position E, intermediate pallet is stretched out fully, and subject pallet is stretched out from partly reaching fully.Intermediate pallet 78 is supported by arrestment mechanism 118.In case of emergency, for example power supply or computer control are malfunctioning, the solenoid (not shown) is in off position, thereby permission rack shaft 152 makes locking lever 148 and sprocket mesh the track that lever 142 is moved to latch 140 by spring biasing rotation, and promotion or pulling subject pallet are backward.Interaction between screw mandrel locking lever 148 and the leadscrew sprocket 144 prevents that screw mandrel 146 from rotating, and guarantees that intermediate pallet 78 can not move.After medical personnel brought back to the position D that is fully retracted with subject pallet 82, the latch 140 insertion shaft levers 142 that are positioned on the subject pallet 82 locked onto retracted position with subject pallet 82.After manually subject pallet 82 being taken to complete basically retracted position D, subject latch 140 comprises a slope, and its impeller-hub lever 142 forces axle 152 contrary springs biasings to be rotated.When axle 152 rotates, screw mandrel locking lever 148 is unclamped from leadscrew sprocket 144, intermediate pallet leadscrew 146 releases.In case this screw mandrel 146 can rotate, manually the pressure that continues backwards is pushed into retracted position with intermediate pallet 78.
Because the end forward in position D intermediate pallet is not loaded basically, also be promoted to the bottom surface of just in time touching intermediate pallet, so intermediate pallet 78 also can skid off back-up block 124 easily even without reduction arrestment mechanism 118 because support lock 124 rigidity.In this way, the staff do not computerized control and/or power supply just can be manually rapidly continuously the push-and-pull subject pallet to idle position A.When adopting computer control and power supply being arranged, saddle can be withdrawn with motor.
The present invention is illustrated with reference to preferential embodiment.After reading over and understanding the front detailed description, can make modifications and changes to the present invention.The present invention is intended to comprise all such modifications and change with itself being built into, the short of claim of this paper appendix or the scope of their equivalent of exceeding.
