Abstract

The embodiment of the invention discloses a positioning method and system. The method comprises the steps of obtaining a starting position and an ending position of a planned scanning range, wherein the starting position and the ending position correspond to a first anatomical position and a second anatomical position of the target object respectively; acquiring a positioning image of the target object on a scanning bed of imaging equipment; identifying a first coordinate and a second coordinate of the target object in the positioning image; determining a target bed size interval according tothe first coordinate and the second coordinate in the positioning image, wherein the target bed size interval refers to the coordinate range of the scanning bed in a space coordinate system when the first anatomical position and the second anatomical position of the target object are transferred to the scanning area of the imaging equipment; and moving the scanning bed based on the target bed sizeinterval. According to the method disclosed by the embodiment of the invention, an operator does not need to observe the body surface of the target object, the dependence on the experience of the operator is reduced, the judgment accuracy of the position corresponding to the actual scanning part is improved, and the positioning efficiency of the scanning bed is improved.

Description

technical field [0001] This specification relates to the field of image diagnosis, in particular to a positioning method and system. Background technique [0002] Medical imaging refers to the interaction of human body or experimental body with the help of some medium in a non-invasive way to obtain images of internal tissues and organs of the target to assist doctors in the diagnosis and treatment of diseases. The correct positioning scan is an important preparation work before the imaging equipment begins to perform the inspection. The positioning mainly refers to that the operator determines the start position and the end position of the scan according to the inspection requirements, and places the corresponding body parts (from The body parts between the scanning start position and the scanning end position) are sent into the scanning aperture (or scanning area) of the imaging device to complete the inspection of the specific scanning range by the imaging device. At pre...
