Embodiment 1

[0033] figure 1 It shows a schematic structural diagram of a system for automatically segmenting and locating prostate cancer on mpMRI according to Embodiment 1 of the present invention; figure 1 As shown, the system includes: AI scheduling module 10, prostate segmentation module 20, prostate cancer intelligent detection module 30 and structured report module 40, wherein,

[0034] The AI ​​scheduling module 10 is respectively connected with the prostate segmentation module 20, the prostate cancer intelligent detection module 30 and the structured report module 40, and is used when the patient scans and the inspection item is a prostate multiparametric MRI (multiparametricMRI, mpMRI) inspection , extracting the header file information of the DICOM image, searching the ADC sequence image based on the header file information, and sending the ADC sequence image to the prostate segmentation module 20 and the prostate cancer intelligent detection module 30;

Embodiment 2

[0061] image 3 A schematic diagram of a system structure for automatically segmenting and locating prostate cancer on mpMRI according to Embodiment 2 of the present invention is shown, as shown in image 3 As shown, the prostate cancer intelligent detection module 30 also includes a judging unit 302, which is connected to the AI ​​scheduling module 10 and used to calculate the sum of the percentage values ​​of all partitions. When the sum of the percentage values ​​is equal to 1, it is judged that the cancer focus is in the prostate Internally, when the sum of the percentage values ​​is less than 1 and greater than 0, it is judged that the cancer focus has extraprostatic invasion; when the sum of the percentage values ​​is equal to 0, it is judged that the cancer focus is not in the prostate; and the judgment data is sent to the AI ​​scheduling module 10.

[0062] The embodiment of the present invention is provided with a judging unit, which can judge whether each cancer foc...

Embodiment 3

[0064] Figure 4 A schematic diagram of a system structure for automatically segmenting and locating prostate cancer on mpMRI according to Embodiment 3 of the present invention is shown; Figure 4 As shown, the prostate cancer intelligent detection module 30 also includes a marker lesion identification unit 304, which is respectively connected to the judgment unit 302 and the AI ​​scheduling module 10, and is used to identify the extra-prostatic invasion data based on the extra-prostatic invasion data. According to the corresponding cancer focus data, it is judged that the cancer focus is a landmark cancer focus; when the extra-prostate invasion data is not received, based on the three-dimensional radial line of each cancer focus and the volume of each cancer focus, the cancer focus with the largest cancer focus volume is identified, Then the cancer focus is judged as a marker focus, and the key image, three-dimensional diameter line and cancer focus volume corresponding to th...

Abstract

The invention provides a system for automatically partitioning and positioning a prostatic cancer for mpMRI. The system comprises an AI scheduler module, which is used for searching an ADC sequence image when a sufferer is subjected to scanning inspection, of which an inspection item is prostate gland mpMRI; a prostate gland partitioning module, which is used for partitioning a prostate gland andpartitioning the prostate gland into a plurality of different zones; an intelligent prostatic cancer detection module, which is used for identifying all cancer focuses of the prostate gland in the ADCsequence image, measuring a three-dimensional radial line and a cancer focus volume of each cancer focus, calculating the percent of a volume of a superposed part between each cancer focus and each zone to the volume of the corresponding cancer focus based zoned image data, and judging that the zone with the maximum percent is a position of the corresponding cancer focus; and a structuring reporter module, which is used for outputting zones where the cancer focuses are located and outputting a PI-RADS score (4 or 5) based on returned results. The invention further discloses a method for automatically partitioning and positioning the prostatic cancer for the mpMRI. According to the system and the method, positions of the cancer focuses can be positioned accurately, whether the cancer focuses invade the outside of the prostate gland or not can be judged, and thus, the working efficiency of doctors is increased.

Description

technical field [0001] The present invention relates to the field of medical information, more specifically, to a system and method for automatically segmenting and locating prostate cancer on mpMRI. Background technique [0002] The main task of prostate mpMRI examination is to detect and locate cancer to guide biopsy. The clinical requirement for mpMRI reports is to clearly write the size and location of each cancer focus. According to clinical routine or international guidelines, each cancer focus should provide location information labeled according to the template. Lack of positioning information, or unclear positioning information, or failure to provide positioning information according to the template, etc., are not standardized. At this time, the value of the image report is limited. [0003] In addition, since prostate cancer is basically multiple, attention should be paid to the most important cancer focus during puncture. This cancer focus is often the decisive ...
