Usage-scene-based medical image volume reconstruction optimization method

Abstract

The invention discloses a usage-scene-based medical image volume reconstruction optimization method. The method comprises: a template library containing a plurality of histogram features is established, wherein each histogram feature has a plurality of mapping functions and a default mapping function; a medical image inputted by a user is obtained, a histogram feature of the image is calculated, matching of the histogram feature to the histogram feature template library is carried out, and three-dimensional reconstruction is carried out on a new medical image sequence by using a matched default mapping function; a mapping function selected by the user is monitored, three-dimensional reconstruction is carried out on the medial image, a usage frequency of the mapping function is updated, andthe mapping function with the highest usage frequency is set as a default mapping function matching the histogram feature template; and if any newly adding / modification / deletion operation of the histogram feature template or mapping function, the histogram feature template library is updated. According to the invention, a method being capable of adapting to the personal diagnosis habits of the doctor is provided; and on the basis of optimization of the mapping function, the volume reconstruction matches the usage scene of the doctor well, so that the film reading efficiency is improved.

Description

technical field [0001] The invention relates to an optimization selection method of a mapping function (including an opacity mapping function and a color mapping function) in a medical image volume reconstruction process, in particular to an optimization method of a medical image volume reconstruction mapping function in a fixed use scene. Background technique [0002] In the volumetric reconstruction, the three-dimensional data needs to be rendered and displayed, and the opacity mapping function and the color mapping function are required in this process. The appropriate opacity mapping function and color mapping function are different in the image reconstruction of different parts produced by different devices. Even if it is the same image, doctors will hope to have different opacity mapping functions and color mapping when viewing different tissues, so as to observe different pathological features. The usage scenarios of doctors are relatively fixed (CT machines, persona...

AI Technical Summary

Problems solved by technology

The usage scenarios of doctors are relatively fixed (CT machines, personal diagnosis habits), and usually 3D processing software will initialize a color mapping table, but this mapping table is fixed for all devices and doctors, so many initial mapping tables cannot be very accurate. To better meet the needs of doctors, adjusting the mapping table is also a time-consuming and inefficient operation
