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： Devices and methods for implementing selective, or asymmetric, attenuation of an x-ray beam. In one example, a filter is provided that is substantially in the form of a wedge where some portions of the filter are thicker, and thus provide greater attenuation, than other, thinner portions of the filter. The filter is situated between the target surface of the anode and the x-ray subject so that x-rays generated by the target pass through the filter before reaching the x-ray subject. Specifically, the filter is oriented so that the thicker portion of the filter receives the higher intensity portion of the x-ray beam, while the thinner portion of the filter receives the relatively lower intensity portion of the x-ray beam. Thus, the gain profile of the x-ray beam is flattened so that the intensity, or flux, of the x-ray beam is relatively uniform throughout a substantial portion of the beam profile.

摘要： Data signal amplification and processing circuitry with multiple signal gains for increasing dynamic signal range. An incoming data signal is processed in accordance with multiple signal gains. The resultant signals have multiple signal values which are compared to predetermined lower and higher thresholds. The desired output signal is: the maximum sample signal value when the maximum value fails to traverse a predetermined lower threshold; the minimum sample signal value when an adjacent larger one of the plurality of sample signal values traverses a predetermined higher threshold; a smaller of mutually adjacent ones of a pair of the plurality of sample signal values when a larger one of the pair of sample signal values traverses the predetermined higher threshold and the smaller value fails to traverse the predetermined lower threshold; and a combination of the smaller and larger ones of the pair of sample signal values when the larger value traverses the predetermined lower threshold and fails to traverse the predetermined higher threshold.

摘要： Disclosed are imaging systems, methods, and computer program products that generate estimates of scattered radiation in tomographic imaging systems, such as cone-beam computerized tomography (CBCT) systems, and the like. In an exemplary embodiment, a first group of projections is taken of an object with the radiation covering a wide band of the object, and a second group of projections is taken of the object with the radiation covering a narrower band of the object. The projections of the second group cover less of the object, but have less scattered radiation. The scattered radiation within the narrower band may be estimated from differences between projections from the first and second groups, or from representations thereof.
