Method and device for realizing automatic zooming of lens of early cancer detector

Abstract

The invention discloses a method and a device for realizing automatic zooming of a lens of an early stage cancer detector, including a camera and a microscope head with a magnification adjustment ring, and a magnification adjustment mechanism controlled by a central control system. The central control system obtains The current magnification of the microscope head is compared with the preset magnification, and the magnification adjustment mechanism is controlled according to the comparison result, and the magnification adjustment mechanism controls the rotation of the magnification adjustment circle of the microscope head to the predetermined location. By comparing the current magnification and the preset magnification, and controlling the rotation of the magnification adjustment circle according to the comparison result, the automatic adjustment of the lens magnification is realized.

Description

technical field [0001] The invention relates to a method and a device for realizing automatic zooming of a lens. 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 three 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...

AI Technical Summary

Problems solved by technology

[0015] 1) The formation process is seldom discovered. If you find symptoms such as hematuria and then check again, it is often already in the middle and late stage;

[0016] 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 "screening";

[0017] 3) The examination process is extremely painful. The current examination method is mostly cystoscopy. For example, men need to insert from the front of the genitals to the bladder

[0018] 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 surface area of ​​the inner wall of the bladder is about thousands of square centimeters

The disadvantages of this adjustment method are: 1) the operation method is manual adjustment, and the hand needs to touch the lens itself, which is not suitable for instruments and equipment that work in a sealed environment such as early cancer detection systems; 2) the hand touches the lens, which may The slight movement of the lens is not suitable for high-precision shooting and detection systems; 3) The magnification of each adjustment is determined by observing the scale under the magnification adjustment circle with the naked eye. Due to the low accuracy of the scale, it is necessary to adjust to the same When the magnification is one, the position of each rotation may be quite different, so that the two magnifications are inconsistent

Although automatic zooming can be realized, but because the control software is only for the lens of our company, it cannot be widely applied to the automatic zooming of all lenses, so that there are restrictions on the lens during application.
