Abstract

The invention discloses a three-dimensional coordinate determination method and device. The method comprises the steps that a volume reconstruction image is obtained, wherein the volume reconstruction image is a two-dimensional image and comprises a three-dimensional object; two-dimensional coordinates of a first position and a second position in the volume reconstruction image are respectively obtained, wherein the first position and the second position are two different positions clicked by a user in the volume reconstruction image; and a first three-dimensional coordinate corresponding to the two-dimensional coordinates in the volume reconstruction image is determined. With the three-dimensional coordinate determination method and the device, the endpoints of a distance to be measured or the vertex of an angle to be measured can be directly selected in the volume reconstruction image, and the problem that a tangent plane reconstruction image needs to be adjusted for times when distance or angle measurement is carried out in the tangent plane reconstruction image is avoided, so that a better medical treatment observation effect is realized.

Description

technical field [0001] The present invention relates to the medical field, in particular to a method and device for determining three-dimensional coordinates. Background technique [0002] In clinical medical applications, volume reconstruction is performed on multiple scanned images to obtain volume reconstruction images. The volume reconstruction images include the three-dimensional information of the scanned object. Space measurement of the anatomical structure, including distance measurement and angle measurement in three-dimensional space. The three-dimensional measurement of bones is of great value in bone correction and plastic surgery; the three-dimensional measurement of organs and lesions is of great value in lesion resection, surgical planning, and radiotherapy planning. However, there is currently a lack of an easy-to-use and accurate three-dimensional space measurement method. [0003] In the prior art, usually through multiple trials and adjustments, a sectio...
