Fig. 5 represents the functional block diagram of this aperture device.
At first, the signal of having imported from operator 9 is transformed to the necessary control signal by operator control part 41, is input to diaphragm control part 42.Diaphragm control part 42 is according to this control signal, makes the CD-ROM drive motor action of the blade of diaphragm 20 that can make blade of diaphragm 20 actions, the blade of diaphragm 20 that order shows selected on indicator 44.Indicator 44, as described later, by each limit that is configured in the monitor 6 that shows the radioscopy image by the frame shape, the luminous body of lighting a lamp in the direction of selected blade of diaphragm constitutes.Also have, making blade of diaphragm 20 information where of moving output to X ray detector 3 (being FPD) and image processing part 43 herein from diaphragm control part 42, the pictorial display in the zone of having been limited by this blade of diaphragm on monitor 6, is controlled according to this.
Secondly, the control method more specifically of blade of diaphragm is described.Fig. 6 (A) one (D) expression is provided with the picture of the monitor 6 of indicator 44.The medium and small thick frame of picture is to be concerned about the zone, is provided with the indicator 44 of frame shape at this monitor display frame periphery.Indicator 44 constitutes each limit corresponding with selected blade of diaphragm and can light a lamp.For example, last blade of diaphragm selected occasion, the top 44U of indicator will light a lamp (Fig. 6 (B)), left blade of diaphragm selected occasion, the left side 44L of indicator will light a lamp (Fig. 6 (C)), the occasion that the infra blade of diaphragm is selected, and the following 44D of indicator will light a lamp, right blade of diaphragm selected occasion, the right 44R of indicator will light a lamp.
According to the number of times of pressing button switch 32 (Fig. 4), switch the selection of the blade of diaphragm that will control by order shown in Figure 7.That is, can be by last blade of diaphragm 51 → left blade of diaphragm 52 → following blade of diaphragm 53 → 56 → attendant exclusion 57 → upward the order of blade of diaphragm 51 is come the switching controls pattern to right blade of diaphragm 54 → full gloss door screen blade (location change in care zone) 55 → full gloss door screen blade (dimension modifying in care zone).
Under the state of Fig. 6 (A) indicator 44 which all do not light a lamp, which blade of diaphragm does not have selectedly yet under this state, even pull hook stick 31 down, which blade of diaphragm can not move yet.
Secondly, push 1 press button 32 and become the control model 51 of glazing door screen blade, shown in Fig. 6 (B), the top 44U of indicator lights a lamp.The patient can pull down up and down under this state hook stick 31 freely carry out on the moving of blade of diaphragm.
Secondly, pressing button switch 32 and become the control model 52 of left blade of diaphragm again, shown in Fig. 6 (C), the left side 46L of indicator lights a lamp.Equally, can about pull hook stick 31 down and carry out the action of left blade of diaphragm.
Secondly, the 3rd pressing button switch 32 and become whole lamina (location change) control model 55, the size constancy in the care zone that is made of 4 pieces of blades more only move to any direction to its position according to the operation of hook stick 31, control according to this.In this occasion, shown in Fig. 6 (D), the indicator 44 on 4 limits is all lit a lamp, and makes the patient can hold pattern.
Have again, pressing button switch 32 and become whole lamina (dimension modifying) control model 57 again, under the state of indicator 44 flickers that make 4 limits, up and down or about pull hook stick 31 down, also can change the size of being concerned about the zone.For example, also can enlarge the center of being concerned about the zone, dwindle as benchmark.
In addition, on one side also can by this control model on one side pressing button switch 32 pull hook stick up and down down, make the size of being concerned about the zone from be concerned about regional auxocardia, dwindle, control according to this.
In addition, be provided with indicator 44 in this example, but, if the viewing area of monitor 6 can guarantee fully that also the demonstration same with indicator 44 carried out in the position that can suit on image.
Also have, the indicator on 4 limits also can be glimmered by whole lamina (location change) control model, often lights a lamp by whole lamina (dimension modifying) control model.Perhaps, also can use the color different to show with control model.
Also have, press button 32 is one with hook stick 31, but, press button 32 and hook stick 31 isolating local divide to be arranged also can obtain same effect.For example replace press button 32, can further reduce operator 9 with foot switch.
Also can replace press button and the discrete switch corresponding with each control model 51-57 of blade of diaphragm is set switching.
Fig. 8 represents the relation of the moving direction of the direction of operating of hook stick and blade of diaphragm.
In control model is the occasion of blade control model, and hook stick is pulled down to illustrated direction, has only blade of diaphragm 21 (with reference to Fig. 3) to move in the direction of thick arrow.Lobus sinister sheet, lower blade, lobus dexter sheet do not move.
In the occasion of each control model of lobus sinister sheet, lower blade, lobus dexter sheet too, hook stick is pulled down to illustrated direction, had only corresponding blade of diaphragm to move in the direction of thick arrow.
In the occasion of whole lamina (location change) control model and the occasion of whole lamina (dimension modifying) control model, corresponding with the direction of pulling hook stick down, each blade of diaphragm 21～24 moves in the direction of thick arrow.Fig. 9 is the block diagram of the control system of expression blade of diaphragm.
Stored the form 62 suitable that the moving direction of the direction of operating of control model, hook stick and each blade of diaphragm is associated in the memorizer of diaphragm control part 42 (with reference to Fig. 5) with Fig. 8.
For example, the operator selects whole lamina (location change) control model, hook stick 31 is pulled down to the direction of hope, will be connected, the signal of representing direction of operating is input to the CPU61 of diaphragm control part 42 with the corresponding switch in the switch that hook stick connects with pulling direction down.CPU61 accepts the signal from hook stick 31, with reference to form 62, drives the driving signal of the blade of diaphragm corresponding with the direction of operating of selected control model and hook stick to motor M1-M4 output.
Each blade of diaphragm is pulled down at hook stick, in the process of switch connection, is controlled and moves to the direction of thick arrow.When hook stick was got back to vertical position, the switch that connects with hook stick all turn-offed, and each blade of diaphragm just stops in this position.
Secondly, illustrate, at the embodiment that has descended the time aspect the configuration of the lamp that is used to confirm the x-ray bombardment district for above-mentioned aperture device.
This is for example shown in Figure 10, makes the filament 28 configuration directions of lamp 25 become 45 ° with respect to each blade of diaphragm 21～24 than length direction.
