[0050] As shown in FIG. 1, the X-ray computed tomography apparatus includes a gantry 201 configured to acquire projection data on an object. The gantry 201 includes an X-ray tube 210 and an X-ray detector 223 . The X-ray tube 210 and the X-ray detector 223 are mounted on a circular-like rotating frame 212 which is driven to rotate by a stage driving device 225 . The central portion of the rotating gantry 212 has an opening, and the object P installed on the patient bed surface 202a of the patient bed 202 is inserted into the opening portion. Furthermore, the rotatable central axis of the rotary gantry 212 is defined by the Z axis (slice direction axis), and a plane orthogonal to the Z axis is defined by the X and Y axes, which are two orthogonal axes.

[0051] The high voltage generator 221 applies a tube voltage between the cathode and the anode of the X-ray tube 210 , and applies a filament current to a filament of the X-ray tube 210 by the high voltage generator 221 . X-r...

[0115] An auxiliary diagnosis and treatment device for acute cerebral infarction constructed according to the present invention will be described below with reference to the accompanying drawings. The auxiliary device for diagnosing and treating acute cerebral infarction processes CT images (spatial distribution of CT values) obtained by an X-ray computed tomography system (CT scanner). In the following description, it is assumed that auxiliary equipment for diagnosing and treating acute cerebral infarction is included in an X-ray CT scanner. The auxiliary device for diagnosing and treating acute cerebral infarction can also be designed separately from the x-ray CT scanner as an independent device.

[0116] As shown in FIG. 13, an X-ray CT scanner according to aspects of the present invention includes a gantry 1 configured to collect projection data on a patient to be examined. This stand 1 comprises an X-ray tube 10 and X-ray detector 23, and X-ray tube 10 and X-ray detector...

[0200] An apparatus for assisting diagnosis and treatment of acute cerebral infarction according to a third embodiment of the present invention will be described with reference to the accompanying drawings. The device according to this embodiment uses a three-dimensional CT image that has been acquired by an X-ray CT scanner. The three-dimensional CT image is a multi-slice type or a volume type that is a collection of three-dimensional pixels. Here, a CT image is described as a multi-slice type.

[0201] As shown in FIG. 31, the X-ray CT scanner used in this embodiment is similar to the corresponding scanner in the second embodiment. This embodiment differs from the scanner in the second embodiment in two respects. First, the image processing section 43 can extract an image of a blood vessel. Secondly, the device also includes a 3D image processing section 51 .

[0202] As shown in FIGS. 32 and 33, a simple CT scan is performed to acquire projection data representing a thr...

Abstract

A cerebral ischemia diagnostic aid device comprising: a storage section for storing a plurality of slices or volume data on a subject's head; an image generating means for generating a tomographic image of a brain based on the plurality of slices or volume data part; an image processing part for processing the tomographic image to generate a contrast highlighting image and a sulcus highlighting image or one of them; and a display part for combining the tomographic image with the contrast highlighting image and the sulcus highlighting image displayed together.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on prior Japanese Patent Applications No. 2003-368893 and No. 2003-368894 filed on October 29, 2003 and enjoys the priority of the above applications, the entire disclosure of which is incorporated herein by reference. technical field [0003] The invention relates to an auxiliary device for the diagnosis of cerebral ischemia, an X-ray computed tomography device with an auxiliary function for the diagnosis of cerebral ischemia, and an auxiliary diagnosis and treatment of acute cerebral infarction by providing useful information for diagnosis and determination of treatment strategies for acute cerebral infarction. Device for cerebral infarction. Background technique [0004] In the medical field, by reading brain X-ray CT images of acute cerebral infarction and its severity to qualitatively determine the location and size of the ischemic region and its severity, and to quickly determine the appl...
