[Application of high-speed thermovisor TV-03 to rapid diagnosis of focal pathology of the nervous system].

The equipment for, and methods of thermovisional examinations developed by the authors and used in 300 patients with focal pathologies of the central and peripheral nervous system are described. In patients with intracranial processes, local changes of the skin temperature on the head usually correlating with the loci of the brain pathology are revealed. The correlation between the asymmetry of the thermal fields and the tumour localization in relation to the brain surface was found to be regular. Peculiarities of the thermographic picture are described with reference to the histobiological characteristics of the tumours. In meningiomas, the zone of the increased luminosity was rounded, homogenous and distinctly outlined; in gliomas reaching the brain surface, this zone is diffuse and less intense. Thermovisional characteristics of traumatic meningeal hematomas with regard to the time of their formation are presented. Acute hematomas were characterized by a lowered skin temperature above them, chronic ones by a brighter luminosity in the zone of their localization. For the first time the thermovisional syndrome of the traumatic foci of brain contusion and smashing is described. Thermovisional appearance of spinal cord tumours, intervertebral disc hernias, injures of peripheral nerves, etc. is also presented.

[Current possibilities and prospects of using gas lasers in medicine. Laser therapy].

Local laser radiation of human organism for therapeutical purposes can be looked upon as an efficient and controlled method of normalization of functioning of a number of organs. Laser units designed on the basis of industrial gas lasers are used on a large scale for treatment of vascular diseases and related ischemias in various parts of the human body.

[Current potentials and outlook for the use of gas lasers in medicine. Laser surgery].

Gas lasers are now in common use in clinical practice due to such advantages as a wide range of wavelengths, high spatial coherence, diversity of power radiations, and adequate reliability. Continuous CO2 lasers and pulse Cu and CO2 lasers recently produced on the industrial basis offer new opportunities to improve the quality of laser surgical interventions, cutting biological tissues with high blood supply and lower water content (bones, fat, burns, etc.), visceral surgery via endoscopes. Further development of fiberoptic communications with due regard to individual laser spectrum and power is beneficial for expanding the range of medical engineering.
