Problems solved by technology

In this case, the light projector only shows the center line of the X-ray irradiation area at the main scanning position, so medical workers cannot correctly identify the X-ray irradiation area, for example, when using another detector for main scanning, etc.

Embodiment Construction

[0018] The X-ray CT apparatus and its control method according to the present embodiment will be described with reference to the drawings.

[0019] figure 1 It is a block diagram showing the outline of the X-ray CT apparatus of this embodiment. figure 2 It is a block diagram showing the configuration of the X-ray CT apparatus 1 .

[0020] like figure 1 and figure 2 As shown, the X-ray CT apparatus 1 mainly includes: a bed mechanism 2 on which a patient (subject H) is placed, a gantry 3 for irradiating X-rays to the subject H during imaging, and a control bed mechanism 2 and the gantry. 3 and the operation control center 4 that generates image data based on the data acquired by the platform 3 .

[0021] The bed mechanism 2 includes an upper panel 21 and an upper panel controller 22 .

[0022] The upper panel 21 can place the subject H on its upper portion.

[0023] The upper panel controller 22, in the state where the subject H is placed on the upper panel 21, moves the...

Abstract

The invention provides an X-ray CT apparatus and a control method of an x-ray CT apparatus. The X-ray CT apparatus has a plurality of projectors, a reception unit, a setting unit, a supporter, and a scan execution unit. The projectors each have a light source on a circumference having a same radius as a rotation radius of an X-ray focal point of an X-ray irradiator and perpendicular to a shaft ofa detected object, each irradiate laser light having an irradiation range simulating an irradiation range of the X-ray. The reception unit receives an instruction for three-dimensionally sliding the projectors as one body. The setting unit sets a position of the projectors via making the projectors slide according to the instruction. The supporter supports a table and three-dimensionally slides the table by a difference between a position of a center of the circumference of the set projectors and a position of a rotation center of the X-ray focal point of the X-ray irradiator. The scan execution unit executes a scan with the table after the sliding as a scan position.

Description

[0001] Cross-reference statement to related application [0002] This application is based on and claims priority from Japanese Patent Application No. 2009-283051 filed on December 14, 2009, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an X-ray CT (Computed Tom Graph) apparatus that irradiates X-rays, detects the X-rays transmitted through a subject, and forms an image, and a control method thereof. Background technique [0004] In a conventional X-ray CT apparatus, before actually starting data collection from a main scan such as a dynamic scan, it is necessary to formulate a scan plan in advance. In the scan plan, set the X-ray tube voltage, X-ray tube current, slice thickness, cone angle, fan angle, gantry tilt angle (tilt angle), reconstruction matrix, main scan position and slave scan that need to be used in the main scan The range of the main scan from the start position to the end positio...
