Iranian Scientists Design New Algorithm for Automatic Diagnosis of Eye Diseases
Iranian researchers at the Faculty of Electrical and Computer Engineering of University of Tehran, under the supervision of Hamid Soltanianzadeh, the head of the Medical Engineering Laboratory, developed a method for the automatic classification of optical coherence tomography images in patients with Age-related Macular Degeneration (AMD).
“In this project, a new algorithm has been designed that uses a multi-scale convolutional structure based on feature pyramid networks to separate healthy people from two disease states, i.e. weight and choroidal neovascularization,” Soltanianzadeh said.
“These networks have been used in image segmentation and object recognition applications; but in this research, by making structural changes, we have used them for classification,” he added.
Soltanianzadeh noted that the use of a multi-scale structure in designing the network allows unrecognizable features in one scale be checked in another scale which increases the classification accuracy.
Iranian scientists have made good progress in production of optical devices.
In a recent development, an Iranian knowledge-based company has produced a Physical Vapor Deposition (PVD) system, for the first time in Iran, to produce optical devices.
“Physical Vapor Deposition (PVD) has been designed based on using electron beam at optic and laser accuracy. It has the capability of thin film coating in special parts,” Mohammad Mirzayee, a representative of an Iranian technological company, said.
The PVD is one of the vacuum coating processes in which the film of coating material is usually deposited atom by atom on a substrate by condensation from the vapor phase to the solid phase, a definition available on the Internet online said.
He explained how the system works and added that a variety of companies in the country use his company's system.
“All companies, technological centers, universities and manufacturing units that operate in the field of manufacturing optical devices, such as Isfahan National Center for Laser and Optical Industries, use the PVD,” the researcher explained.
