Abstract: The present invention pertains to an apparatus and method for adaptive exposure in imaging systems. An x-ray source for producing x-ray radiation and an x-ray detector for measuring amount of x-ray radiation passing through the human patient and striking the detector can be used. A tomographic image of the human patient or a tomosynthetic image of the human patient can be generated. Region of interest filtering and equalization filtering can be utilized. Filtering can be accomplished with a mechanical shield or shutter or with electronic control of the x-ray source.

Abstract: A method includes assessing tumor margins and discriminating between tumor and non-tumor tissues by analyzing the compositional make-up of smoke produced during cautery resection of tissues.

Abstract: The present invention pertains to an apparatus and method for X-ray imaging a human patient. A vacuum bell bonded to an X-ray radiation-permeable window that can emit X-ray radiation from a plurality of spots located 1 cm from its edge, a collimator, and a detector are used. A ring of stationary X-ray sources can also be used with a stationary collimator and a rotating slot collimator and detector. An X-ray beam can be aligned in an X-ray system by establishing a position of the beam with respect to a moving collimator at a number of points in time, monitoring the velocity of the collimator, navigating the beam to a calculated position of a hole in the collimator, and correcting the alignment of the beam based on the location of the beam on the detector.
