A series of special topics on the introduction of the technology of nodule Zinni
【Preface】Zhengzhou Zhongpu Medical Equipment Co., Ltd. is a high-tech enterprise focusing on the research and development, production and sales of tuberculosis smear, acid-fast dyeing, intelligent scanning products. The company has a number of national invention patents for tuberculosis smears diagnostic technology, and is one of the enterprises with the most complete product categories and the most mature technology of tuberculosis smears, acid-fast dyeing, intelligent scanning. The company launched the fully automatic tuberculosis smear intelligent scanning scanner, which is a new generation of tuberculosis smear intelligent scanning and diagnostic equipment independently created by Zhengzhou Zhongpu after 4 years. It has the obvious characteristics of extremely fast scanning speed, high accuracy, and flux upgrade in the original machine.

AI software system is the core competitiveness of TB scanner, not the microscope!
As we know, there are two scanning imaging platforms for tuberzini's scanner at present, one is microscope type, the other is optical tube type (only the optical part of the microscope), and the microscope type is divided into two kinds: domestic high-end microscope and imported microscope. No matter what kind of microscanning imaging platform is used, its function is to magnify the scanning target.
The sharpness of the traditional artificial microscope image depends not only on the hardware configuration of the microscope itself (the higher the hardware configuration, the better the image effect), but also on the artificial focus perception. The whole operation of the microscope is manually completed. Whether it is manual focusing or moving observation, the configuration of the microscope will give people different experiences.
And the automatic tuberculosis scanner from visual field focus to complete image acquisition, is completely by computer software algorithm and software control program precision control of the motor to complete (artificial intelligence AI technology), the instrument can provide a clear vision of the picture completely depends on the software algorithm, algorithm is good to pick out the most clear picture, algorithm is not good, The selected picture may not be clear.
So it's not the microscope itself that determines whether an instrument can provide a clear picture, but the software algorithms associated with it -- the capabilities of artificial intelligence (AI) technology.
There is no possibility of manual participation in the whole scanning process of automatic scanning instrument, and the operator is not able to participate in the focusing of the instrument and the identification of which is the clearest under the field of vision. The operator is more of a manual audit of the field of vision recognition picture results provided by the instrument, and for the audit results, the ordinary scanner only provides an identification picture. Considering the unevenness of the smear, Zhengzhou Zhongpu provides fine-tuning video audit technology of the whole field of vision, so as to solve the problem of different focus pictures caused by the uneven thickness of the tuberculosis smear itself, and provide more accurate possibility for the diagnostic doctor's audit.
If the scanner does not have a good algorithm software control system, even if the microscope provides the top configuration, it is difficult to pick out a best field of vision picture, of course, good configuration will be icing on the cake, but the imaging is clear or not depends on the algorithm software, not the configuration of the microscope platform.
No matter how high the microscope configuration is, it is not always possible to accurately capture and select the clearest image during the focusing process, and it is even possible to provide a blurred view of the image out of focus.
Mycobacterium tuberculosis is a rod-shaped bacterium that is 3-8 microns long and 0.3-0.6 microns in diameter. The microscopic diagnostic standard of tuberculosis smear staining is observation and diagnosis under 100 times oil microscope. The reason why 100-fold oil lens is used for observation is mainly because the tuberculosis bacterium itself is too small. Under Ziezini's staining, 100-fold oil lens can be used to better distinguish the unique knotlike structure of the tuberculosis bacterium, which is different from the diagnostic interference caused by other impurities (red impurity interference is also caused by decolorization).
Note:
For the examination of tuberculosis bacilli, the standard has been clear to use 100 times oil lens for observation, but there is no specific requirement for what kind of microscope standard should be used, and the hardware requirement for the diagnosis of tuberculosis smears is not high. Medical units with general conditions can complete diagnosis with conventional microscopes, while well-known medical units with better conditions purchase imported brand microscopes for diagnosis, which entirely depends on the economic conditions of medical units.
It can be seen that the core of whether the automatic tuberculous scanner can provide the clearest picture of the field of vision is entirely the algorithm software control system, and the development of this system lies in the technical understanding and accumulation of the R&D personnel. Zhengzhou Zhongpu has developed the deep learning algorithm recognition technology based on the neural network technology, and provides the original algorithm software patent technology with independent intellectual property rights. Artificial intelligence (AI) technology is used to replace human brain recognition, making the image provided more perfect.
After repeated comparison, Zhengzhou Zhongpu R & D team adopts the domestic high-end microscope as the scanning platform (its performance benchmark is the medium and high-end imported microscope, its price is more favorable than the imported microscope). Zhengzhou Zhongpu fully meet the needs of diagnosis at the same time, to provide more cost-effective configuration, so that users.
Zhengzhou Zhongpu R & D team in-depth analysis of the characteristics of tuberculosis smear scanning -- seize the key core algorithm software and cost-effective domestic high-end microscopic platform, maximize the positive rate of tuberculosis smear reading, to provide users with more cost-effective products.
Technical comparison：
Zhengzhou Zhongpu tuberculosis smear intelligent scanner:We should grasp the key core algorithm software and cost-effective domestic high-end microscopic platform, and try our best to improve the positive rate of reading tuberculosis smears, so as to provide users with more cost-effective products.
Ordinary scanners: Displaying expensive imported microscopes and hiding the scanner's core algorithms are the key facts.
Microscopes are not the core competitiveness of scanners. The real competitiveness is artificial intelligence (AI) software system!
Zhengzhou Zhongpu has been committed to improving the tuberculosis scanner film reading positive rate and independent thinking, hard!
Zhengzhou Zhongpu automatic tuberculosis Zini staining scanner -- the thought of bringing core competitiveness and helping to improve the positive rate of reading film.
Zhengzhou Zhongpu tuberculosis smear intelligent scanning platform more applications: automatic tuberculosis smear intelligent scanning platform, in addition to providing tuberculosis smear intelligent scanning diagnosis, can also be expanded to: Intelligent diagnosis of blood smear Plasmodium scanning, liquid based cell intelligent diagnosis, thyroid puncture cell intelligent diagnosis, bacterial smear Gram staining intelligent diagnosis, human body fluid parasite (egg) intelligent diagnosis, clinical blood smear white blood cell analysis diagnosis, clinical bone marrow cell smear intelligent diagnosis and other medical microbial morphological intelligent diagnosis techniques.
