摘要： Described are methods and systems for scanning at least a portion of a patient with a gamma detector mounted on an arm extending towards the patient. One described method includes: obtaining data indicative of coordinates of points on the outer surface of the patient; determining a target position for the gamma detector based on the data indicative of the coordinates; and causing the gamma detector to detect gamma radiation from the patient when the gamma detector is at the target position.

摘要： The disclosure describes methods and apparatuses for scanning a region of interest (ROI) by a gamma detector. An exemplary method includes determining, for each of multiple detector configurations, a respective weight based on an absorption profile, associating each of a plurality of portions of the ROI with a respective gamma attenuation value; and detecting gamma radiation from multiple detector configurations for time periods allocated among the detector configurations based on the weights determined.

摘要： A method of producing a denoised medical image at a specified resolution, comprising: a) denoising an original medical image acquired at a resolution higher than the specified resolution; and b) reducing the resolution of the image, after denoising, to the specified resolution, using a nonlinear resolution reduction procedure that preserves more fine detail in the image than a linear resolution reduction procedure would.

摘要： A method of reducing noise in an image, comprising: a) for each pixel being examined in the image, selecting a set of search pixels; b) calculating a value of one or more features of a neighborhood of each search pixel, and a value of corresponding features of a neighborhood of the pixel being examined; and c) calculating a reduced noise grey value for each pixel being examined, based on raw or transformed grey values of its search pixels, with greater sensitivity to those with one or more feature values similar to those of the pixel being examined; wherein calculating the value of at least one feature comprises calculating a characteristic of a distribution of raw or transformed grey values of pixels in the neighborhood, other than a mean grey value of all pixels in the neighborhood.

摘要： A method for generating a three-dimensional (3D) low-resolution image from a 3D high-resolution medical image, reduces resolution in the direction of the slices and the resolution is maintained in the other directions. The 3D high-resolution medical image is a plurality of 2D images having an axial resolution in an axial direction in which the plurality of 2D images were acquired, the method including the steps of: decomposing each of the plurality of 2D images using an invertible band-pass decomposition technique to generate a plurality of transformed data sets, wherein each of the transformed data sets corresponds to one of the plurality of 2D images; weighting each pixel in each of a portion of the transformed data sets within the portion of the transformed data sets using a non-uniform weight vector to generate a plurality of weighted transformed data sets; combining the plurality of weighted transformed data sets for each portion into a single new transformed data set for each portion in a non¬ linear manner; and generating a 3D low-resolution image, having a first resolution in the axial direction, from each of the single new transformed data sets using an inverse of the invertible band-pass decomposition technique, wherein the first resolution in the axial direction of the 3D low-resolution image is lower than or equal to the axial resolution.
