Abstract:
In a method to generate a nuclear medicine image reconstructed from an average of multiple subsets of acquired counts of a dataset, having an image quality characteristic aligned with that of a corresponding image obtained from a reconstruction of all counts of the dataset, a phantom data acquisition is used to determine an appropriate post-processing step necessary to align each image quality characteristic which provides a desired alignment of a given image quality characteristic. The determined post-processing step is applied to the combination of the multiple reconstructions.
Abstract:
In a methods and apparatus for generating an image for display from medical image data of a subject, image data is processed to reconstruct a pre-image data set, and a filter applied to the pre-image data set to produce a filtered image for display, while a value of a variable is obtained from the pre-image data set, for display with the filtered image. The value obtained from the pre-image data can be used for quantification of a feature of the medical image data.
Abstract:
A method for facilitating comparison of image data from a given medical imaging protocol with archive image data, includes obtaining subject image data from a scan of a subject using the medical imaging protocol, obtaining archive image data differing from the subject image data in a given variable, determining a modifier usable to reduce the difference between the archive and subject image data, using the modifier to modify one of the subject image data and the archive image data to reduce the difference, and comparing the modified archive or subject image data with the subject or archive image data.
Abstract:
A method for facilitating comparison of medical image data captured using first and second combinations of scanner and reconstruction protocol (‘systems’) includes using a modifier to modify image data of a first subject captured using a first system to reduce a difference from image data of a second subject captured using a second system.
Abstract:
A method and system are provided for facilitating decision making, such as in a clinical setting. In accordance with this technique, a set of encoded guidelines are executed to identify information that may be used to generate patient management options. The information is acquired, if available. Based on the encoded guidelines and the acquired information, a set of patient management options are generated and provided to one or more reviewers for review and selection of a patient management option.
Abstract:
In a method and apparatus for generating an enhanced image for display from medical imaging data of a subject, a feature of interest in the imaging data elongated in at least one dimension is determined. A location of a line through the imaging data along the feature of interest is obtained, and a projection image along the line is generated from the imaging data.
Abstract:
In a method and apparatus for identifying a region of interest in medical imaging data of a subject is described, an intensity projection image is generated from the medical imaging data. The medical imaging data is then processed to find one or more maxima in the medical imaging data. The found maxima are compared with the intensity projection image, and one of the maxima which is not represented in the intensity projection image is identified.
Abstract:
In a method or apparatus for generating, from medical image data of a subject from a functional imaging modality, a modified intensity projection image for display. An intensity projection image data set is obtained from the image data. A segmentation for the image data is obtained. Based on information from the segmentation, a modified display property is calculated for at least one voxel of the intensity projection image data set.
Abstract:
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.
