PNIPU: Device for histological analysis

2021: Creation of a device for automatic histological analysis

On April 19, 2021, the Perm National Research Polytechnic University (PNIPU) announced the creation of a device for automatic histological analysis. It allows the detection of cellular pathologies in humans and animals. The accuracy of the technology is from 82% to 92%.

Histological analysis is used to find changes in cells that could indicate oncopathology. This process is quite long, and the development of PNIPU automates it. Due to the elimination of the human factor, the accuracy of the analysis increases, and the load on medical personnel decreases, say the developer.

In PNIPU created a device for automatic histological analysis it detects cancer

The process of automatic examination begins by loading samples of material into the apparatus, preparing a histological preparation and scanning them. Then specially designed computer algorithms process the obtained image. The device using neural networks "decrypts" it, finding indicators of tissue destruction that are characteristic of different pathological processes.

The researchers developed a technique for automated diagnosis determination based on the analysis of pathology indicators. To do this, scientists conducted simulation simulations to determine these indicators.

The ultimate goal of scientists is to create a "histologist robot," which will perform all functions: from loading samples of material to issuing a result.

We conducted a series of experiments on the recognition of cellular pathologies, the results of which were evaluated by a histologist laboratory assistant. In the process, we used a histological wiring system - a Leica histological processor, a rotary microtome ThermoScientific NM 325 and other equipment, "said Professor of the Department of Information Technology and Automated Systems of Perm Polytechnic, Doctor of Technical Sciences, Associate Professor Sergey Kostarev.[1]
