摘要： A tumor treatment apparatus may include an array of collimated CZT detectors configured to intersect a known coordinate and measure gamma radiation activity, for example at 511 keV. A radiation delivery system may be configured to direct radiation through the known coordinate on the basis of the gamma radiation activity. A translatable and rotatable table may be configured to support a tumor host, wherein the tumor is positionable relative to the known coordinate on the basis of the gamma radiation activity emitted by the tumor and measured by the array of collimated CZT detectors. Radiation from the radiation delivery system may be delivered to the tumor at the known coordinate, and may be delivered in an intra-operative surgical environment.

摘要： A radiation detector(16) having a first detector layer (24) and a second detector layer (26) encircles an examination region (14). Detectors of the first layer include scintillators (72) and light detectors (74), such as avalanche photodiodes. The detectors of the second detector layer (26) include scintillators (62) and optical detectors (64). The scintillators (72) of the first layer have a smaller cross-section than the scintillators (62) of the second layers. A group, e.g., nine, of the first layer scintillators (72) overlay each second group scintillator (62). In a CT mode, detectors of the first layer detect transmission radiation to generate a CT image with a relatively high resolution and the detectors of the second layer detect PET or SPECT radiation to generate nuclear data for reconstruction into a lower resolution emission image. Because the detectors of the first and second layers are aligned, the transmission and emission images are inherently aligned.
摘要翻译：具有第一检测器层（24）和第二检测器层（26）的辐射检测器（16）围绕检查区域（14）。第一层的检测器包括闪烁体（72）和光检测器（74），例如雪崩光电二极管。第二检测器层（26）的检测器包括闪烁体（62）和光学检测器（64）。第一层的闪烁体（72）具有比第二层的闪烁体（62）更小的横截面。第一层闪烁体（72）中的一组，例如九个覆盖每个第二组闪烁体（62）。在CT模式中，第一层的检测器检测透射辐射以产生具有相对高分辨率的CT图像，并且第二层的检测器检测PET或SPECT辐射以产生用于重建成较低分辨率发射图像的核数据。因为第一和第二层的检测器被对准，所以传输和发射图像是固有的对准的。
