Abstract

The embodiment of the invention provides a lesion volume measurement method and device, and solves the problem that an existing lesion volume measurement mode is low in accuracy. The lesion volume measurement method comprises the following steps: acquiring lesion symptom contour distribution information in medical image data of a plurality of parallel layers based on an instance segmentation model; calculating the number of lesion pixels of each lesion based on the lesion symptom contour distribution information; obtaining the pixel interval and the parallel layer interval of the medical imagedata; and calculating the total volume of the lesions based on the number of the lesion pixels of each lesion, the pixel spacing and the parallel layer spacing.

Description

technical field [0001] The present application relates to the technical field of image analysis, in particular to a lesion volume measurement method, device, electronic equipment and computer-readable storage medium. Background technique [0002] The 2020 novel coronavirus pneumonia is characterized by rapid development, and an accurate treatment method has not yet been fully formulated. In the process, CT images undertake quantitative methods such as the number and size of lesions. For images, the average person cannot perform volume quantitative measurement of the three-dimensional state very well. It is necessary to calculate the number of pixels in each layer and the volume of each pixel, and manual calculation is extremely difficult. However, according to the new crown imaging guidelines, the key factors in the development of lesions are volume and density, and the change of volume cannot be done manually. [0003] There are some ways to obtain the lesion volume in the...
