Patent Searching and Data


Title:
MEDICAL IMAGE PROCESSING APPARATUS AND MEDICAL IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/162911
Kind Code:
A1
Abstract:
The present invention provides information that is an effective aid in diagnosis of chronic obstructive pulmonary disease from thoracic volume images. The storage unit (112) of the medical image processing apparatus stores the data for multiple images of differing respiratory phases that represent the configuration of a subject's thoracic region. A vector-calculating unit (121) calculates the amount of movement of an area among the multiple images for each pixel or region. By combining at least two from among the amount of movement, a feature value determined from image pixel values and the rate of change in the size of a region, a level-determining unit (123) determines a level, which relates to the severity of chronic obstructive pulmonary disease, for each pixel or region.
