medicine, in particular, reflectometric examinations and measurements of cavities of animals or human, for example, for examination of respiratory tracts, digestive tract, etc. SUBSTANCE: the device has a flexible hose that is inserted in the cavity to be examined through the canal under examination. The remote end of the hose is positioned past the canal zone being examined. The first converter converts the activation signal obtained from the signal generator to an excitation signal that is transmitted to the hose internal cavity. The reply signal, depending on the local deformation of the hose in the zone being examined, is received by the second converter and subjected to an analysis with due account made for the excitation signal. The analysis unit and the computer produce an image on the screen indicating the results of the examinations. EFFECT: enhanced accuracy of measurement of stenosis of the canal being examined, giving information on tissue elasticity. 23 cl, 7 dwg
