Embodiment Construction

[0028] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present application as recited in the appended claims.

[0029] CT oblique scanning is also a CT scanning method that can be used at present, such as figure 1 As an example, a scanning state during inclined scanning is illustrated. The scanning object 11 lies on the scanning bed 12, and the scanning frame 13 scans the scanning object 11 obliquely, that is, the scanning frame 13 has a certain inclination angle. Such as figure 1 As indicated i...

Abstract

The application provides a scanning data processing method and device. The method comprises the steps that scanning data obtained through CT scanning are received; the scanning data are determined to be obtained through CT inclined scanning, and the data field of inclined scanning is a cube; and inverse transformation is performed on the scanning data through a transformation matrix, wherein the transformation matrix is used for representing the coordinate system transformation relationship between the data field of inclined scanning and a standard placement data field. The post-processing image display quality of CT inclined scanning can be enhanced by the scanning data processing method and device.

Description

technical field [0001] The present application relates to medical equipment technology, in particular to a scan data processing method and device. Background technique [0002] During CT (Computed Tomography, computerized tomography) scanning, a series of cross-sectional scan data of the scanned object (for example, the scanned object can be a human body) can be obtained. The cross-sectional scanned data can be called data slices, and the CT device can pass These data slices are processed by a post-processing system. The post-processing system is usually used to process human body diagnostic images. The post-processing system can display the processed images through interpolation, segmentation, projection, etc. based on the data slices. [0003] The analysis and processing of the post-processing system can only be based on data slices that are perpendicular to the horizontal plane of the scanning bed of the CT equipment. At present, some scans can obtain better results when ...
