METHOD ESTIMATING VOLUME OF LOWER EXTREMITIES BY STRUCTURED ILLUMINATION

摘要

FIELD: medicine.SUBSTANCE: invention relates to medicine, specifically to cardiovascular surgery, and can be used for measurement of volume of lower extremities. Patient is placed on a rotating metal platform. Platform is located in a room without natural illumination. One leg of patient is placed in front of other at 10 cm. Patient is illuminated with laser light with wavelength 830 nm. During one revolution of platform, continuing 60 s, radiation of lower extremities is detected with an infrared sensor. Infrared sensor is located at a distance of 1.5 m from platform.EFFECT: method enables accurate and non-invasive measurement of volume of lower extremities due to use of structured illumination and rotating platform.1 cl, 1 dwg
