Embodiment Construction

[0046] Hereinafter, preferred embodiments of the X-ray imaging apparatus, image processing display apparatus, and computer program product of the present invention will be described in detail with reference to the accompanying drawings. In addition, a case where the present invention is applied to an X-ray angiography apparatus for X-ray imaging of blood vessels such as coronary arteries will be described below. In addition, plaque (arteriosclerotic plaque) will be described below as an example of a vascular lesion that occurs in a blood vessel, but the present invention can be similarly applied to other types of vascular lesion.

[0047] First, the concept of displaying depth information in the X-ray angiography apparatus of the first embodiment will be described. figure 1 This is a diagram for explaining the concept of displaying depth information in the X-ray angiography apparatus of the first embodiment. The X-ray angiography apparatus according to the first embodiment, ...

Abstract

An X-ray imaging machine is configured such that a three-dimensional blood-vessel information creating unit creates information concerning a three-dimensional blood-vessel core line and a position of a plaque in a subject blood vessel based on three-dimensional volume data obtained from an image taken by an X-ray computed tomography apparatus. A plaque-depth information image creating unit creates a plaque-depth information image on which the plaque is differently displayed in accordance with whether the plaque is present in front of or in the back of the three-dimensional blood-vessel core line with respect to a projection direction, based on the created information concerning the three-dimensional blood-vessel core line and the position of the plaque. An X-ray image display unit displays the created plaque-depth information image over an X-ray image in a superimposed manner.

Description

[0001] This application enjoys the benefit of priority of Japanese Patent Application No. 2007-180761 filed on July 10, 2007 and Japanese Patent Application No. 2008-121516 filed on May 7, 2008, all of which are cited in this application content. technical field [0002] The present invention relates to an X-ray imaging device such as an X-ray angiography device, an image processing display device, and a computer program product, and particularly relates to a technique for supporting treatment by inserting a linear structure such as a guide wire into a blood vessel. Background technique [0003] Conventionally, there has been a treatment method in which a linear structure such as a guide wire or a catheter is inserted into the coronary artery of the heart to enlarge the narrowed part or blocked part of the coronary artery. This treatment method is called "PCI (Percutaneous Coronary Intervention, percutaneous coronary intervention) treatment". In this PCI treatment, an X-ray...
