MULTICHANNEL RADIOTHERMOGRAPH Russian patent published in 1997 - IPC

FIELD: radio engineering; multichannel contact measurements of radiothermal radiation of bodies, including medicine for determining temperature field of human internal tissue. SUBSTANCE: newly introduced in device are 2N microwave switches, 2N-1 circulators, scale-of-n frequency divider, counter, register, digital-to- analog converter, main storage, decoder, demultiplexor, N analog storage cells, N-1 matched loads, thermoelectric cooler, and temperature sensors. Device operates without transients temperature processes with channels and provides for measuring transient temperature processes with constant relaxation equal to time constant of matched loads. EFFECT: reduced absolute error in measuring radiothermal temperature field of bodies. 1 dwg
