摘要： The present invention relates to a pixellated detector with an enhanced structure to enable easy pixel identification even with high light output at crystal edges. A half-pixel shift between scintillator crystals (50) and detector pixels (12) enables the identification of a crystal (50) from four detector pixels (12) instead of nine pixels in case of optical crosstalk. Glass plates without any mechanical structuring may be used as a common substrate (60) for detectors and scintillators.

摘要： When reconstructing low-collimation nuclear scan data (18) (e.g., SPECT) into a nuclear image volume (19), a spatial frequency-dependent (SFD) filter function is applied in Fourier space to the reconstructed image (19) to improve image resolution given a predefined number of reconstruction iterations and/or to reduce the number of reconstruction iterations required to achieve a predetermined level of image resolution. Size of an object to be imaged is determined, and the SFD filter function is determined or generated based on signal power spectrum (and/or modulated transfer function) data, object size, and desired image quality (or number of reconstruction iterations). The SFD filter function amplifies higher-energy components (e.g., corresponding to a lesion or tumor, or the like) of the spatial frequency spectrum to improve viability in a low collimated nuclear image (19) using fewer reconstruction iterations.
摘要翻译：当将低准直核扫描数据（18）（例如，SPECT）重建成核图像体积（19）时，在傅立叶空间中将空间频率依赖（SFD）滤波函数应用于重建图像（19）以改善图像给定预定数量的重建迭代和/或减少实现预定水平的图像分辨率所需的重建迭代次数。确定要成像的对象的尺寸，并且基于信号功率谱（和/或调制传递函数）数据，对象大小和期望的图像质量（或重建迭代次数）来确定或生成SFD滤波器功能。 SFD滤波器功能放大空间频谱的较高能量分量（例如，对应于病变或肿瘤等），以使用更少的重建迭代来改善低准直核图像（19）中的存活力。

摘要： A gantry free nuclear imaging system (10) images a region of interest (ROI) (16). The system (10) includes one or more radiation detectors (20) generating radiation data indicating the location of gamma photon strikes. The system includes a reconfigurable frame (22) positioning the radiation detectors (20) at fixed viewing angles of the ROI (16) and at least one processor (44, 48). The processor (44, 48) receives the radiation data from the radiation detectors (20) and reconstructs an image of the ROI (16) from the received radiation data.
