FIELD: medicine. ^ SUBSTANCE: invention refers to medical equipment, namely to diagnostic apparatuses for studying vascular status. The apparatus comprises an ultrasound signal emitter, an ultrasound echo receiver, an amplitude data processor, a phase data processor, a border detector for detecting border distribution between a blood flow region and an inferior coat and between an middle coat and an adventitious membrane derived from at least one processing result prepared by the amplitude data processor, and at least one processing result prepared by the phase data processor, and a IMT calculator referring to the position data specifying a border position between the blood flow region and the inferior coat, and to the position data specifying a border position between the middle coat and the adventitious membrane. ^ EFFECT: use of the invention allows higher measurement accuracy of vascular IMT value. ^ 18 cl, 7 dwg |
