Problems solved by technology
Therefore, it is difficult to identify the correspondence between the position of the vessel in the 3D-IVUS image represented in the coordinate system along the vessel centerline and the position of the vessel in real 3D space
[0008] The method disclosed in Patent Document 1 does not solve the above-mentioned problems
Furthermore, since the method disclosed in Patent Document 1 requires hardware such as an MPS sensor and a system for analyzing the signal value of the MPS sensor, it is not easy to adopt the method disclosed in Patent Document 1

A tubular structure, such as a blood vessel, of a subject is extracted from each of a three-dimensional image representing the tubular structure and a three-dimensional intra-tubular-structure image that has been generated from plural tomographic images of the tubular structure obtained by performing tomography on the tubular structure plural times from the inside of the tubular structure along a path in the tubular structure. Further, an arbitrary range in one of the tubular structure extracted from the three-dimensional image and the tubular structure extracted from the three-dimensional intra-tubular-structure image is correlated with a corresponding range in the other one of the tubular structures. Further, a projection three-dimensional image is generated by projecting an image of a specific structure included in the range in the three-dimensional intra-tubular-structure image into the correlated range in the three-dimensional image.
Description
technical field [0001] The present invention relates to a device for reconstructing images of the inside of tubular structures derived from intravascular ultrasound (IVUS) diagnostics, optical coherence tomography (OCT) or the like. In addition, the present invention also relates to a method and a program for reconstructing an image inside a tubular structure, and a medium storing the program. Description of related technologies Background technique [0002] In recent years, it has become known to use two-dimensional tomographic images of tubular structures such as blood vessels in image-based diagnosis of tubular structures. The two-dimensional tomographic image is generated based on image signals of the tubular structure acquired by scanning the inside of the tubular structure while rotating a probe attached to the leading end of a catheter in the tubular structure. Intravascular ultrasound (IVUS) diagnosis and optical coherence tomography (OCT) techniques, which serve ...
