Image processing device, image processing system, image processing method, and image processing program

An image processing method comprising:

• determining, by a control unit, when an input is received of at least one cross-sectional image obtained using a sensor configured to move in a lumen of a biological tissue, whether a deformation spot that is on an inner surface of the biological tissue and that has been deformed by pressing an elongated medical device inserted into the lumen is included in the at least one cross-sectional image;
• and
• specifying, by the control unit, a position of the medical device based on a position of the deformation spot when it is determined that the deformation spot is included in the at least one cross-sectional image.

A non-transitory computer-readable medium storing an image processing program for causing a computer to execute a process comprising:

• determining, when an input is received of at least one cross-sectional image obtained using a sensor configured to move in a lumen of a biological tissue, whether a deformation spot that is on an inner surface of the biological tissue and that has been deformed by pressing an elongated medical device inserted into the lumen is included in the at least one cross-sectional image;
• and
• specifying a position of the medical device based on a position of the deformation spot when it is determined that the deformation spot is included in the at least one cross-sectional image.
