Abstract
A shutter arrangement and activator device for a diagnostic X-ray machine of the type which rotates about the patient while scanning with thin beams for analysis by computers for storing and reconstructing the results in tangible form. The shutter mechanism is positioned between the X-ray source and a detector unit and includes a movable apertured shutter plate disposed between a pair of slotted plates. The shutter plate is automatically moved into and out of the X-ray path by means of a patient detector system. A belt or band, which permits the passage of X-rays but not light, is disposed on the patient and triggers the detector system.
