Abstract: Embodiments of the invention relate to a method and apparatus for displaying information. In a specific embodiment, at least two pluralities of voxel values for a corresponding at least two functions with respect to at least a portion of a subject can be obtained. The at least a portion of the subject can have a plurality of local volume elements, where the at least two pluralities of voxel values for the corresponding at least two functions each correspond to the plurality of local volume elements. In this way, there is a voxel value for each function for each local volume element of the portion of the subject. Each of the at least two pluralities of voxel values represents the value of the corresponding function of the at least two functions for the corresponding plurality of local volume elements. A representation is created where the value of one of the at least two functions is on a first axis and a count of voxels is on a second axis.

Abstract: A prediction system for grouping hepatocellular carcinoma includes an image capturing unit and a non-transitory machine readable medium. The non-transitory machine readable medium storing a program which, when executed by at least one processing unit, predicts a hepatocellular carcinoma group of the subject patient with hepatocellular carcinoma. The program includes a reference database obtaining module, a first image preprocessing module, a feature selecting module, a classifying module, a second image preprocessing module and a comparing module.

Abstract: The invention provides a novel method of high-resolution quantifiable pulmonary regional ventilation imaging using a package of computer programs, including deformable image registration and local volume change calculation on 4-D or breath-hold CT images. High resolution 3D ventilation images have been generated using this technique with superior quality. The deformation matrices between different respiration phases are calculated using deformable image registration and applied to calculate local volume change ?V between respiration phases. The invention provides less image-noise and mismatch sensitivity than other techniques based on CT images, and is less expensive than nuclear medicine imaging. Implemented clinically, the method can derive a patient's pulmonary ventilation information from the same set of 4-D CT images, providing a cheaper but more accurate method to generate clinical lung ventilation image.
