1. Apparatus for measuring movable part structures within a living body, said apparatus being intended to co-operate with an ultrasonic scanner having an ultrasonic head provided with a plurality of ultrasonic transmitter units, and being arranged to generate pulsation diagrams representing movements of the movable part structures in a pulsatile vessel in the living body, comprising:

  • control means, operative to sequentially activate the ultrasonic transmitter units in an ordered sequence for, between each activation of one of the ultrasonic transmitter units, defining at least two selected measuring lines, each of which is associated with a respective associated ultrasonic transmitter unit and for scanning each said measuring line in a sequence using said associated transmitter unit and producing a signal indicative thereof;

    vessel wall indicating means, arranged to receive the indicative signal obtained in response to the scanning using the selected ultrasonic transmitter units for scanning two vessel boundaries with each scan of each said measuring line to generate information used to calculate a change in condition of such boundaries in relation to a preceding indication of said measuring lines;

    computing means for calculating a pulsation diagram for each said measuring line for the pulsatile vessel from the information obtained from the vessel wall indicating means; and

    presentation means for presenting the pulsation diagrams.
