摘要： A photon detector includes a sensor array of optical sensors disposed in a plane and four substantially identical scintillation crystal bars. Each optical sensor is configured to sense luminescence. Each of the four scintillator crystal bars being a rectangular prism with four side surfaces and first and second end surfaces, each scintillation bar has two side surfaces which each face a side surface of another scintillation bar, and each scintillation crystal bar generating a light scintillation in response to interacting with a received gamma photon. A first layer (80) is disposed in a first plane disposed between and adjacent facing side surfaces of the four substantially identical scintillation crystal bars with a light sharing portion (82) adjacent the first end surface and a reflective portion (84) adjacent the second end surface. A second layer (68) is disposed in a second plane orthogonal to the first plane and disposed between and adjacent facing side surfaces of the four substantially identical scintillation crystal bars with a light sharing portion (88) adjacent the second end surface and a reflective portion (90) adjacent the first end surface.

摘要： In Positron Emission Tomography, a time window (260) and an energy window (225) are dynamically adjusted, based on an attenuation map, count rate, clinical application, discrimination tailoring, and/or offline discrimination tailoring. Detected radiation events are filtered using the dynamically adjusted energy and time windows into scattered events, random events, and true events. The true events are input to image reconstruction, correction, and error analysis.

摘要： When correcting for artifacts on an attenuation map caused by an artifact source in a computed tomography image, nuclear images are reconstructed two or more times, each time using a different correction technique or uncorrected attenuation data. Corresponding voxels in the reconstructed images are compared to identify local areas that change, i.e., are fragile and therefore low-confidence, and areas that do not vary or exhibit little variance among the plurality of reconstructed images and are thus accorded a higher confidence. The reconstructed nuclear image is overlaid with color encoding indicative of the amount of confidence accorded to each voxel value obtained by attenuation-corrected tomographic reconstruction.

摘要： A hybrid imaging system including a first imaging system configured to acquire low resolution anatomical data of a first field of view of an anatomical structure. A second imaging system is configured to acquire functional data of the first field of view of the anatomical structure. A reconstruction processor is configured to reconstruct the functional data based on attenuation data into an attenuation corrected image. In response to the attenuation corrected image showing regions of interest, with the first imaging system or another imaging system acquiring high resolution data of one or more portions of the first field of view containing the regions of interest. The reconstruction processor reconstructs the high resolution anatomical data into one or more high resolution images of the regions of interest.
