摘要： A multi-mode cone beam computed tomography radiotherapy simulator and treatment machine is disclosed. The radiotherapy simulator and treatment machine both include a rotatable gantry on which is positioned a cone-beam radiation source and a flat panel imager. The flat panel imager captures x-ray image data to generate cone-beam CT volumetric images used to generate a therapy patient position setup and a treatment plan.

摘要： A radiation detector includes a conversion element that converts an incoming radiation beam into electrical signals, which in turn can be used to generate data about the radiation beam. The conversion element may include, for example, a scintillator that converts the radiation beam into light, and a sensor that generates the signals in response to the light. The conversion element can be used in different schemes or data collection modes. For instance, the conversion element can be oriented normal to the radiation beam or transverse to the radiation beam. In either of these orientations, for example, the detector can be used in an integrating mode or in a counting mode.

摘要： A multiple mode digital X-ray imaging system providing for preprocessing “binning” of analog pixel signals from a detector array by selectively summing, within the detector array, adjacent pixel charges on a row-by-row basis and selectively summing, within detector array readout circuits, the previously summed pixel charges (by rows) on a column-by-column basis. An array, or mapping, of “defective pixel” flags is used to identify defective pixels within the detector array, with such flags being added to, or inserted into, the incoming data stream for dynamic processing along with the incoming pixel data. A buffer and filter is used to perform still image capture during the radiographic mode of operation and to recursively filter incoming data frames during the fluoroscopic mode of operation by summing a scaled amount of pixel data from prior data frames with a scaled amount of incoming pixel data from the present data frame.
