Problems solved by technology

An obvious defect of this method is that obvious image artifacts are left at the splicing of the two 3D volume data, which is not conducive to the identification and diagnosis of doctors, and the CT scanning at the two positions requires additional moving process of the scanning device, which increases the Overall scan time, prone to unwanted motion artifacts in images

Abstract

The invention discloses an imaging method. The imaging method comprises the following steps: putting an object in a detection region, and biasing a detector; moving an imaging system along a longitudinal Z axis; enabling a ray source and a detector to synchronously move along the periphery of the object, scanning and acquiring data, and performing completion and faultage according to the data. According to the imaging method disclosed by the invention, the detector biasing and spiral trajectory scanning are combined to solve a problem that an image assembly method used by a conventional CT (computed tomography) imaging (particularly cone-beam CT imaging) generates artifact on the assembly image for the cone-beam CT covered by a long Z axis, so that a usage area of the detector is reduced, and the system cost is saved.

Description

technical field [0001] The present invention relates to an imaging method, in particular to a method for using a computer to perform photography on a tomography, and a device for implementing the method. Background technique [0002] Since the invention of the first CT prototype in 1971, CT imaging technology has played an important role in modern medical diagnosis. CT imaging equipment with a large imaging field of view is an urgent need for clinical applications. However, since CT detectors are expensive, the size of the detector will significantly affect the manufacturing cost of CT equipment. Configuring large-size detectors will significantly increase the manufacturing cost of CT imaging equipment. [0003] In order to obtain a larger CT imaging coverage volume, helical scanning is an ideal way to increase the imaging field of view. According to the search results of the academic paper database, German scientist Willi Kalender developed the first helical scanning CT ...
