    摘要: In a method and apparatus for analyzing medical imaging data of a subject from an imaging modality using a tracer, data from detection of tracer emission events at least one region of a scanned imaging volume are obtained, and the data processed to establish sub-periods or time points within a scan period for the emission events. A rate of change of emission events per unit time for a given region is then calculated, for example by obtaining a number of emission events in each sub-period in the given region, and fitting a line through the values for the sub-periods.

    摘要: In methods and an apparatus for analyzing a selected region of interest in medical image data of a subject, an initial image data set is obtained, and the initial image data set is filtered to generate a filtered data set. The filtering includes computing, for each voxel of the initial image data set, a value of intensity for a standardized volume of interest centered on that voxel. A user selection of a region of interest in the initial image data set is registered, and from the filtered image data set a value of intensity for the selected region of interest is computed.

    摘要: In a method and apparatus for analyzing and correcting medical imaging data of a subject, an image data set is obtained from a scan of the subject at a first time point with respect to a defined time origin. A measurement of a time-dependent variable is then determined for the data set, and an estimated value for the time-dependent variable at an estimate time point is extrapolated from the data set.

    摘要: In a method and apparatus for calibrating image data from a given medical imaging protocol, reference image data is obtained from a scan of a reference object using the medical imaging protocol, and the obtained reference image data of the reference object is compared to standard reference image data for the reference object. The obtained reference image data is then modified to reduce an error between the obtained reference image data and the standard reference image data. Subject image data id then obtained from a scan of a subject using the medical imaging protocol, and modified based on the modified reference image data. A value of a variable is obtained from the modified subject image data, for display with unmodified subject image data.

    摘要: In a method or apparatus of comparing two image data sets from medical imaging data of a subject, a first, three-dimensional image data set of the subject is obtained. A second, two-dimensional image data set of the subject is also obtained. The first data set is registered with the second data set. Data from the first, three-dimensional image data set is processed to determine a voxel in the first data set which corresponds to a given pixel in the second, two-dimensional image data set.
