Through making arm support 4 rotation around the axon of body M to be detected, and realize the rotation (from the head side of to be detected body M observe, to the left rotation direction be LAO, the rotation direction on round about right side be RAO) of C shape arm 1 around the axon of body M to be detected.The base portion of arm support 4 (end that is keeping the opposition side of C shape arm 1) is supported on the side surface part of telescopic arm 8, and near said supporting surface, is fixing actuating device (gear) 9 with rotatable mode.Actuating device 9 and pinion-gearing (pinion gear) 10 interlocks, pinion-gearing 10 are installed on the output shaft that is arranged on the CD-ROM drive motor M2 in the telescopic arm 8.Through the turning effort of this CD-ROM drive motor M2, and C shape arm 1 is with arm support 4 rotation around the axon of body M to be detected.In addition, rotary encoder R2 is equivalent to the position detection unit that rotation direction and amount of spin to CD-ROM drive motor M2 detect.
And said telescopic arm 8 is because along flexible up and down with the orthogonal direction of the axon of body M to be detected, so remain on the bottom of the turning arm 11 of L word shape.The other end of turning arm 11 is fixed on the rotary body 12, and rotary body 12 is pedestal with the rotation base station 13 on the variola wooden partition that is fixed on the inspection chamber of placing the X ray camera head, and is rotated.CD-ROM drive motor M3 makes 12 rotations of this rotary body, and rotary encoder R3 detects through rotation direction and amount of spin to rotary body 12, and the position of the surrounding space of the body M to be detected of C shape arm 1 is detected.
The formation of control system that is used for controlling each rotation is as shown in Figure 3.At this, for representing with same-sign, and omit explanation with the common formation of control system shown in Figure 7.
Among the present invention; On target rotation information memorizer 40; Store among each storage switch 30a～30i that appends operation board 30 of rotation information being used for, display lamp 31a～31i and this switch designs are integral type, and according to through the selected rotation information of storage switch 30a～30i; And the action that is used for indicating C type arm 1 switch 30j is set, display lamp 31j also is arranged to one-piece type with this storage switch.
Utilize CPU21 and pass through display control unit 24, come these display lamps 31a～31j is lighted control.In addition, in the present embodiment, be display lamp 31a～31j and storage switch 31a～31j are designed to one-piece type, but can certainly utilize light emitting diode (light-emitting diode, LED) wait and be arranged in addition storage switch near.
Secondly,, the processing of before shooting, carrying out in advance is described, that is, will be described to the order that the target rotation information is stored in the memory area with the corresponding target rotation information of each storage switch memorizer 40 with reference to flow chart shown in Figure 4.In addition, as the target rotation information, describe as example with situation about frequently using in the angiocardiography inspection cited in the first precedent.
At first, through switch not shown in the operation board 20 is operated, the target rotation information is set sets the pattern of handling.Then, come target setting rotation information (direction of rotation and the anglec of rotation) through operation board 20.For example, shown in Figure 8 like what explain in the precedent formerly, to be 30 ° on the CRAN direction, to be 30 ° mode and target setting rotation information (step S1) on the LAO direction.Operation board 20 is equivalent to the input block among the present invention.
Secondly, CPU21 is through display control unit 24, and the pairing display lamp 31a of the corresponding storage switch 30a of the target rotation information that makes and set neglects bright go out suddenly (step S2).In addition; Owing to can easily specify especially according to the anglec of rotation that sets to direction of rotation; Therefore as long as formulated the corresponding tables of the anglec of rotation and storage switch in advance; Just this corresponding tables capable of using easily according to the target rotation information that is chosen relevant storage switch specifies especially.
Under this state, press with step S1 in the corresponding storage switch of neglecting the bright state that goes out suddenly of target rotation information set.At this, be the storage switch 30a that presses the position that is provided in the expression CRAN direction of appending on the operation board 30 and LAO direction, and only press the storage switch 30a that neglects the bright state that goes out suddenly, just can get into step S4 (step S3).Therefore, the operator can positively select pairing storage switch.
When pressing the storage switch of neglecting the bright state that goes out suddenly, CPU21 changes to illuminating state (step S4) with the pairing display lamp of said storage switch.Thus, can judge as the selecteed fact of the storage switch of storage object very clearly.
Then, through the not shown setting storage switch on the push dish 20, and the target rotation information that CPU21 will set (CRAN30 °, LAO30 °) is stored in the target rotation information memorizer 40 (step S5).At this, CPU21 is equivalent to operating unit of the present invention with the setting storage switch.In addition, even press the setting storage switch,, just do not carry out storage action as long as storage switch is not illuminating state (as long as non-selected correct storage switch) in step S4.CPU21 is equivalent to the control unit that reads in of the present invention.
At last, judge whether end setup and handle (step S6) separately.At this, the target rotation information that remaining needs are set has eight, therefore turns back to step S1 and proceeds to handle.
As stated, repeating step S1 is to step S6, with this, with the target rotation information be stored in the corresponding target rotation information of each storage switch 30b～30i memorizer 40 in.
In said embodiment, CPU21 and display control unit 24 are equivalent to indicative control unit of the present invention.

Secondly, through press append operation board 30 switch 30j is set, and make CPU21 begin to be rotated control, so that the target rotation information of being read among the step U2 consistent with actual rotation information (step U3).Thus, even shooting person's mistake is pressed storage switch, C shape arm 1 can not begin yet the rotation, up to press switch 30j is set till, so can prevent the rotation of the C shape arm 1 that shooting person does not expect, thereby can protect body M to be detected or shooting person.But, also can be rotated control at the time point of pressing pairing storage switch.
Spin Control is carried out as follows; Promptly; CPU21 drives this motor M1 rotates it on the CRAN direction; And since the rotational angle of spinning encoder R1 be 30 ° mode and motor M1 is rotated control, and drive this motor M2 it rotated on the LAO direction, and since the rotational angle of spinning encoder R2 be 30 ° mode and motor M2 is rotated control.
In addition; On operation board 20, switch is being set, said switch carries out a kind of and user after C shape arm 1 arrival target location, want to extinguish storage switch display lamp require corresponding setting; And set according to whether having carried out this pattern, and ensuing action is with difference.
Promptly; CPU21 judges whether arrive the pattern that behind the target location pairing display lamp is extinguished sets (step U4); When the pattern of extinguishing is not set, enter to step U5, make the display lamp 31a of this storage switch 30a neglect bright going out suddenly up to the target rotation information with till actual rotation information is consistent; At the target rotation information time point consistent, make the pairing display lamp 31a of this storage switch 30a light (step U5) with actual rotation information.As stated, stored with the corresponding target rotation information of operated storage switch after, through continuing that the pairing display lamp of this storage switch is lighted, also can easily grasp the storage switch that in the conventional treatment process, then will operate.In addition, in the present embodiment, be to switch to illuminating state, but can certainly switch to the bright state that goes out suddenly of neglecting from illuminating state from neglecting the bright state of going out suddenly.
On the other hand; When setting the pattern of extinguishing; The display lamp 31a of pairing storage switch is neglected brightly to go out suddenly; With till actual rotation information is consistent,, make the pairing display lamp 31a of storage switch 30a extinguish (step U6) up to the target rotation information at the target rotation information time point consistent with actual rotation information.
Meanwhile, this is provided with the pairing display lamp 31j of switch 30j also is when the target rotation information is consistent with actual rotation information, and termination is neglected bright going out suddenly and extinguished.Thus, shooting person can judge very clearly whether the target rotation information is consistent with actual rotation information.
Secondly, CPU21 controls not shown high pressure generation portion, penetrates required high voltage so that X ray is exposed to the sun and is supplied in the X-ray tube 2, carries out X ray with this and exposes to the sun and penetrate, and obtain radioscopic images (step U7) from X-ray detector 3.
At last, judge whether to finish to make a video recording and carry out branch process (among the step U8).At this,, repeat operation from step U1 to step U8 so turn back to step U1 owing to must carry out the shooting of required eight the remaining directions of angiocardiography inspection.When carrying out said repetitive operation, shooting person can be easily from nine storage switch 30a～30i that append operation board 30, select to follow needed target rotation information, therefore can be easily and promptly carry out the shooting of a plurality of directions.
