Abstract
To provide an image processing device and a spinal canal evaluation method that can evaluate the spinal canal stenosis in an identified cross-sectional position, the image processing deviceextracts a vertebral region from a series of tomographic images in which at least a part of the spine was scanned and calculates a length in the anteroposterior direction of an object for each cross section in each vertebral region. Also, a cross section including a spinous process is identified based on the calculated length in the anteroposterior direction of an object in each vertebral region, the spinal canal stenosis is evaluated by setting the identified cross-sectional position to be analyzed, and then the evaluation results are displayed. Hence, stenosis evaluation can be performed for various shapes of the spinal canal region in which a closed space hardly appears on an image due to many gaps.
