摘要：
FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to means for measuring dispersion transverse waves. Method of vibrometry consists in single issuance of propagation pulse, focused on excitation area in area of interest in order to set transverse wave and issue multitude of tracking pulses for sampling, more than once, in each of multitude of target locations on associated monochromatic transverse wave. Sampling consists in obtaining samples by scanning multitude of target locations by pulse in separate ducts and, with each issuance of pulses of transmission of tracking from multitude of pulses, obtaining by means of simultaneous scanning multitude of samples in multitude of target locations, samples represent data for application in determination of rate of evaluated transverse wave propagation. Method additionally includes determination, for specified part of propagation/tracking sequence, phase difference by taking into account delay between samples, to determine rate of evaluated transverse wave propagation. To realise method used are: machine-readable carrier and ultrasonic device, containing matrix of converters for single issuance of propagation pulse, focused on excitation area in area of interest to set transverse wave and issue multitude of tracking pulses for sampling.EFFECT: application of invention makes it possible to reduce risk of tissue or converter overheating.15 cl, 8 dwgИзобретение относится к медицинской технике, а именно к средствам измерения дисперсионных поперечных волн. Способ виброметрии заключается в единичной выдаче импульса распространения, сфокусированного на области возбуждения в представляющей интерес области для установления поперечной волны и выдачу множества импульсов отслеживания для взятия проб, более одного раза, в каждом из множества целевых местоположений на ассоциированной монохроматической поперечной волне. Причем взятие проб состоит в получении проб сканированием множества целевых местоположений импу
