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.

摘要： The detector of the present invention is suitable for use in a radiation therapy simulator machine. The detector comprises an X-ray image intensifier tube to convert X-rays into photons, a linear array of photodiodes to convert the photons to electrical signals, optical means for coupling the photons to the linear array of photodiodes, and electronic signal processing means for conditioning the signals from the photodiodes. The conditioning includes the use of low noise, phaselocked sampling electronics, implementation of a dual sampling technique for increasing dynamic range, implementation of a linearizing technique for increasing the accuracy of the measurements, and implementation of techniques for adjusting the measurements for point spread and background noise effects.

摘要： Disclosed is a low cost computer tomographic (CT) scanner system specifically designed for radiation therapy treatment planning. A 512-channel photo-diode array with digitizing electronics converts image intensifier optical projection data directly into digital signals and has a dynamic range on the order of 100,000:1. The new simulator includes a rotating gantry, an X-ray generator with radiographic and fluoroscopic modes and a therapy style patient support assembly. Results on head and body size phantoms indicate that the simulator X-ray generator and image intensifier tube (IIT) with multi-channel photo-detector can produce photon statistic limited CT images. Software and hardware compensation methods are described which minimize geometrical distortions. Low noise, high input impedance electronics are employed which are phase-locked to the line frequency. A dual sample interval method is employed which effectively increases the range of the digital signal produced by the front-end electronics by three additional bits.

摘要： Disclosed is a method for improving the dynamic resolution of an imaging system. The method employs a dual sampling or exposure technique which samples light from an image intensifier over a long and a short sample interval. When the resulting measurement for the long sample interval exceeds a threshold level, the short sample interval measurement is used, multiplied by a scaling factor. Below the threshold the long sample interval is used.
