Discover in less than a minute cancer cells are closer thanks to an advanced artificial vision developed in Ecuador the Venezuelan scientist Oscar Chang.
The engineer, who is in the Andean country as part of the Prometheus Project, develops a program of advanced computer vision, computer aided, for use specifically in testing gentle scraping of the cervix, better known as Pap order to identify malignant cells.
“A technician will take about 20 minutes analyzing Pap sample, with this program we can do it in a minute Another advantage is that it does not tire the view of the technical, so that samples do not accumulate and faster diagnoses are made, which helps treat. time cancer if the cells are discovered, “Chang says.
The system is a software developed by Venezuela, which works through a network of artificial neurons. To train networks Pap real plates made of Ecuadorian patients were used.
The technique for networks learn to identify what they want is known as Deep learning . This is a learning system for networks using different layers to make these readings. Layers are handled and this specific system requires at least six layers. After placing the information in the program, it is responsible for scanning the sample go on the screen and will see the result: an image of the sample on which to found a cancer cell, the system contains a small circle, which identifies it as evil.
The project is 85% advanced and researcher expects that by April next year is finished.
“The idea is to build a prototype and give it to a health center. The costs for these analyzes would fall considerably and patients would benefit, “he explains.
The engineer, also expert in robotics and mechatronics, says not only to discover cancer cells serves its software, but also for other investigations, which are ongoing.
says Oscar Chang that currently five students perform different theses from machine vision system. In one stand use to diagnose Chagas disease with only a drop of blood; another, records the number of people using the public bus system Ecuador, and the third is used to classify strawberries.
