A scanning method and device

Abstract

The invention provides a scanning method and device. The method comprises the steps of determining a reference picture according to a scanning protocol and / or patient information, obtaining an initial position for scanning, starting scanning from the initial position for scanning, judging whether a picture obtained through scanning has a preset feature or not in the scanning process, and stopping scanning if yes. As can be seen, the stop of scanning depends on the condition that the picture obtained through scanning has the preset feature determined according to the reference picture, and the subjective experience is not depended on. Therefore, compared with the prior art, the precision of a scanning range can be improved.

Description

technical field [0001] The present application relates to the field of electronic information, in particular to a scanning method and device. Background technique [0002] Computed tomography (Computed Tomography, CT) is a commonly used clinical examination method at present. A general CT scan is divided into the following steps: 1. Perform a positioning scan on the patient, and obtain a plain film image after scanning, such as figure 1 shown. 2. The doctor sets the target scanning area on the plain image, figure 2 for in figure 1 The target scan area (dotted circle outline area) set above. 3. CT performs CT scanning on the range of the human body corresponding to the target scanning area to obtain a CT image. [0003] It can be seen from the above process that the scanning of various parts of the human body is based on the scanning area artificially set by the doctor on the plain image, that is to say, the determination of the scanning range of the affected part of th...

Problems solved by technology

Therefore, it is inevitable that there will be errors between the artificially set scanning area and the actual required scanning area, such as figure 2 In the invalid area shown, the artificially set target scanning area is larger than the actual required scanning area. Therefore, the human body scanning range corresponding to the target scanning area is larger than the actual range of the affected area that needs to be scanned. In this case, the patient will be subjected to unnecessary Radiation, on the contrary, if the artificially set target scan area is too small, the body scan range corresponding to the target scan area is smaller than the range of the affected area that actually needs to be scanned, which cannot meet the needs of diagnosis

[0004] It can be seen that how to improve the accuracy of the scanning range has become an urgent problem to be solved in view of the phenomenon that the scanning range is too large or too small in the existing scanning method
