FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, namely to ultrasound diagnostic systems. System contains ultrasound sensor for obtaining succession of ultrasound images as perfusion of contrast substance in tissue takes place, unit for calculation of parameter of contrast substance accumulation time for tumour and for normal tissue and unit for calculation of ratio of accumulation time parameter for tumour and accumulation time parameter for normal tissue. In the second version system contains ultrasound sensor for obtaining succession of ultrasound images of linearly dependent data of echo-signal from tumour and tissue that surrounds it as perfusion takes place, unit for calculation of time intensity of contrast substance for linearly dependent data of echo-signal of tumour and for data of echo-signal of normal tissue and unit for calculation of difference curve for linearly dependent curves of time intensity for tumour and for normal tissue.
EFFECT: application of the invention makes it possible to eliminate impact of changes of procedure between sessions of therapy control.
