Urine-based early-stage bladder cancer examination method and system

Abstract

The invention discloses a urine-based early-stage bladder cancer examination method and system. The method comprises the following steps: (a) making a pathology slide of urine; (b) acquiring an image of the pathology slide through an image acquisition mechanism with a microscopic lens; (c) acquiring the area ratio K of cell nucleuses and cytoplasms of all cells in the image; (d) comparing the area ratio K and a preset area ratio range, and examining suspected cancerous cells according to the comparison result. With adoption of the method and system, complete examination and comparison of the acquired cell information can be realized so as to rapidly acquire the examination result of the cancerous cells, as a result, accurate first-hand data is provided for a doctor to confirm cancerous cells in a follow-up process.

Description

technical field [0001] The invention relates to a urine-based early bladder cancer detection method and system. Background technique [0002] Cancer is one of the most common fatal diseases in the world today. Millions of people die from cancer every year around the world. In the process of facing this century-old disease of cancer, human beings have never found effective treatments and drugs. [0003] The proliferation speed of cancer cells is calculated by doubling time, 1 becomes 2, 2 becomes 4...and so on. The average doubling time of gastric cancer, intestinal cancer, liver cancer, pancreatic cancer, and esophageal cancer is 31 days; the doubling time of breast cancer is more than 40 days. As cancer cells multiply, the more advanced the cancer, the faster it develops. [0004] Cancer can be divided into 3 stages, [0005] The first third can be prevented and cured; [0006] One-third of the symptoms can be alleviated through treatment, early detection and early trea...

AI Technical Summary

Problems solved by technology

[0013] 1) The formation process is seldom discovered. If hematuria and other discomfort signs are found to be checked again, it is often already in the middle and late stage

[0014] 2) After being magnified thousands of times under the microscope, a standard pathological slide needs about tens of thousands to millions of "fields of view". At present, the resources of expert doctors are scarce, and most of them are done in the case of "suspect" by outpatient doctors. Final diagnosis, impossible to achieve "check"

[0015] 3) The inspection process is extremely painful. The current inspection method is mostly cystoscopy. For example, males need to insert from the front of the genitals to the bladder.

[0016] 4) It is very easy to miss inspection - the bladder is an "inverted pear shape", the effective inspection area of ​​cystoscopy is only a few square centimeters, and the inner wall surface area is about thousands of square centimeters
