Abstract

The invention discloses a fast curved surface reconstruction method for a multi-modal multi-contrast medical image and a storage medium. The method comprises the following steps: importing a multi-modal multi-contrast image; selecting two adjacent points as initial seed points for the target blood vessel segment in the image; performing automatic center line search; in the searching process, taking the first initial seed point as a starting point, controlling the searching direction through the second initial seed point, and conducting point-by-point searching on the center line of the target blood vessel segment; smoothening the center line; scanning the smoothed center line along a user-defined direction to obtain an original curved surface required by curved surface reconstruction; and unfolding the original curved surface to obtain a curved surface reconstruction result. According to the method, the center lines of multiple contrast images such as a CT blood vessel image, an MRI bright blood image and an MRI black blood image can be rapidly extracted. In addition, according to the method, a new data structure is adopted to display a two-dimensional plane image, and resampling distortion of a curved surface image is avoided.

Description

technical field

[0001] The invention relates to the field of medical equipment, in particular to a fast curved surface reconstruction method and a storage medium for multi-mode and multi-contrast medical images. Background technique

[0002] Both CT and magnetic resonance imaging (MRI) can perform three-dimensional high-resolution imaging of blood vessels in various parts of the human body. However, the contrast of vessel images acquired by these devices varies widely. For example, CT angiography generally requires the injection of contrast agents, blood vessels and bones show high signal, and muscle fat shows low signal; MRI uses different scanning sequences according to different clinical needs, and blood vessels may show high signal relative to surrounding fat, muscle and other background tissues. Intensity (bright blood image) or hypointensity (dark blood image).

[0003] Surface reconstruction can fully display the longitudinal section of a single or multiple blood ve...
