Embodiment Construction

[0034] Hereinafter, an X-ray computed tomography apparatus (Computed Tomography: hereinafter referred to as an X-ray CT apparatus) according to the present embodiment will be described with reference to the drawings.

[0035] The X-ray CT apparatus has a Rotate / Rotate-Type in which the X-ray tube and the X-ray detector are integrally rotated around the subject, and a plurality of X-ray detection elements arranged in a ring are fixed, and only the X-ray tube revolves around the subject. Various types such as Stationary / Rotate-Type that rotate around the body, and this embodiment can be applied to any type. In addition, in recent years, commercialization of so-called multi-tube type X-ray computed tomography apparatuses in which multiple pairs of X-ray tubes and X-ray detectors are mounted on a rotating frame has progressed, and development of peripheral technologies has been progressing. In this embodiment, it is applicable regardless of a conventional single tube type X-ray co...

Abstract

According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube to generate X-rays, X-ray detector to detect the X-rays transmitted through an object, top to place the object, rotation driving unit to rotate a rotating frame with the X-ray tube and the X-ray detector around the object, movement driving unit to relatively reciprocate the rotating frame and the top over a plurality of times along a long-axis direction of the top, and scan control unit to control the movement driving unit in the relative reciprocal movement such that moving loci of the X-ray tube corresponding to the respective forward movements are matched with each other and moving loci of the X-ray tube corresponding to the respective backward movements are matched with each other.

Description

technical field [0001] Embodiments of the present invention relate to an X-ray computed tomography apparatus. Background technique [0002] In recent years, one of scanning methods of an X-ray computed tomography apparatus (Computed Tomography: hereinafter referred to as an X-ray CT apparatus) includes helical reciprocating scanning. The helical reciprocating scan is an imaging technique in which the X-ray tube is continuously rotated on a circular orbit around the subject and the top plate is continuously reciprocated. Hereinafter, regarding the reciprocating movement of the top plate, imaging on the forward path is referred to as forward path scanning. Regarding the reciprocating movement of the top plate, imaging on the homeward path is called homeward path scanning. [0003] According to the helical reciprocating scan, the X-ray tube (or X-ray detector) draws a helical trajectory (hereinafter referred to as a helical trajectory) relative to the subject. Thereby, a tom...
