Problems solved by technology

However, due to the limited selection of the scan length of the scout image and the deviation of the scan length of the scout image required by human judgment, it often takes multiple operations to obtain satisfactory results.
For example, the scanning operator selects the scanning length of the positioning image as 512 mm after judgment at the beginning, but after the scanning is completed, it is found that the scanning length cannot completely cover the area to be scanned, and the actual length of the area to be scanned is 530 mm; However if figure 1 There is no suitable option in the pre-defined table shown, only 768mm can be selected to scan the scout image again

Embodiment Construction

[0014] see figure 2 The control device for the scan length of the positioning image of the present invention is used in a computed tomography imaging system 100, the computed tomography imaging system 100 has a movable hospital bed 10, the patient 60 lies on the movable hospital bed 10 and moves along with the The hospital bed 10 is moved to scan scout images.

[0015] The scanning of the positioning image starts from a fixed data collection position 30 , the movable bed 10 moves towards the data collection position 30 , and the scanning of the positioning image ends when a predetermined scanning end position 20 reaches the data collection position 30 .

[0016] Before positioning image scanning, a signal source 40 is set on the predetermined scanning end position 20, and the scanning operator can intuitively set the signal source 40 at the desired position, thus avoiding the need for scanning operations in the existing method Personnel empirically estimate the length of the...

Abstract

The present invention proposes a device and method for controlling the scanning length of a positioning image. Before the scanning of the positioning image, it is convenient and intuitive to set a signal originating from a scanning end position, and calculate the signal before the scanning end position reaches a fixed data collection position. A delay time is obtained, so that the system stops scanning the positioning image after the delay time, so as to achieve the purpose of precisely controlling the scanning length of the positioning image.

Description

technical field [0001] The invention relates to a computerized tomography imaging technology, in particular to a control technology for positioning image scanning. Background technique [0002] In computerized tomography imaging inspection, it is often necessary to scan a topogram before a formal scan, and then determine the final scanning range according to the topogram. [0003] The general steps of scanning the positioning image are to define a scan start position on the movable hospital bed of the computed tomography imaging system, and the scan start position is generally located at the data acquisition position of the computed tomography imaging system; Select the direction of movement of the mobile bed, and figure 1 Select the scan length for this scout from the predefined table shown. [0004] The above-mentioned method needs to artificially and abstractly judge the moving direction of the movable hospital bed and select the scanning length of the required position...
