Patent number: 9968313Abstract: A fluoroscopic system is disclosed with capability of differential exposure of different input areas of an image intensifier. The x-ray beam solid angle is limited by a collimator that is relatively near to the focal point of the x-ray tube, to occupy an area smaller then the input area of the image intensifier. Means to deflect the electron beam of the x-ray tube in two dimensions are constructed with the x-ray tube to provide scanning capability of the complete input area with full control on the motion function. The collimator may also be moved to control beam size and/or position at the image intensifier.Type: GrantFiled: January 7, 2013Date of Patent: May 15, 2018Assignee: CONTROL RAD SYSTEMS INCInventor: Haim Zvi Melman
