    摘要: A system in which a fluid flows characterized by a change with time in space. A preselected place in the system is monitored to collect data at two or more time points correlated to a system event. The data is indicative of a system parameter that varies with time as a function of at least two variables related to system wash-in and wash-out behavior. To select time points a calibration map is calculated using color hue indicative of wash-out and color intensity indicative of wash-in. A color coded output map is developed. The calibration map, the color coded output map and image are novel implementations.

    摘要: The present invention provides a method of registering image data for a series of images acquired over a period of time. The images may be acquired from a medical imaging device, such as an MRI scanner. The method allows image-by-image registration to a partially compressed dataset in which motion artifacts are suppressed in a series of target images generated to resemble the original dynamic data. The registration process is refined with each iteration of the process. The method uses Principal Component Analysis which allows accurate registration to be performed without the need to make any assumptions about pharmacokinetic model parameters, which not only avoids the problems of accurate model-fitting but permits the use of much larger target areas of the dataset.

    摘要: The present invention discloses a method and apparatus for brain perfusion magnetic resonance imaging (MRI) technique with the removal of cerebrospinal fluid (CSF) pixels. This invention utilizes a CSF/brain-contrast-enhanced image, wherein the CSF/brain-contrast-enhanced image is defined as the signal difference between CSF and brain matter divided by a standard deviation of air background random noise is larger than 3, acquired from the subject's brain, and applies a segmentation technique to remove the CSF pixels. After removing the CSF pixels on parametric images, the extent of brain tissue with delayed perfusion can be better identified. By using a good region of interest enclosing the correct delayed-perfusion region, the measurement on the tissue volume and perfusion parameters would be more accurate than the area contaminated by CSF pixels.

    摘要: A method for performing computer-assisted lesion assessment includes acquiring contrast enhanced MRI data. A region of interest is identified. Kinetic properties, morphological properties and pattern of enhancement are determined for the identified region of interest. A score is calculated for each of the kinetic properties, morphological properties, pattern of enhancement. A cumulative score is calculated for the identified region of interest. The scores are provided to a medical practitioner to assist in diagnosing the identified region of interest.

    摘要: Methods, systems, devices and compounds for managing imaging data, such as time series imaging data. The method may include selecting a set of representative voxels from a plurality of voxels in the imaging data, and associating each representative voxel with a voxel database for storing information. For each given voxel in the time series imaging data, at least one corresponding representative voxel may be determined from the set of representative voxels, and information from the given voxel may be aggregated in the voxel database of the determined corresponding representative voxel.
