Title:
IMAGE PROCESSING DEVICE AND METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/158593
Kind Code:
A1
Abstract:
An image processing device that processes a plurality of cross sectional images obtained with optical coherence tomography (OCT) by rotating an imaging core and moving same inside a catheter in the axial direction, wherein the image processing device: stores data pertaining to the cross sectional images by associating same to information about the position in the axial direction at the time each cross sectional image was obtained; extracts, from a plurality of cross sectional images, a first cross sectional image where a disappearing section in which a portion of an external elastic membrane contained in a vascular tomographic image is determined to disappear starts, and a second cross sectional image where the disappearing section ends; and obtains the stored information about the position in the axial direction for the first cross sectional image and the second cross sectional image and then calculates, on the basis of the difference in the information about the position in the axial direction, an ablation range, over which the ablation spans, in the location corresponding to the disappearing section.
