1. Method of acquiring medical ultrasound images using ultrasound equipment provided with a probe and a screen for displaying images produced in real time comprising the steps of:

  • a) acquiring at a first date with said equipment during a first examination of a patient a first image of a region of the body of said patient to be examined with a particular angle of incidence and inclination of said probe, said first image comprising contours of vascular structures; and

    b) acquiring at a second subsequent date with said equipment during a second further examination of said patient a second image of said region of the body of said patient by the following steps;

    1) producing on the display screen an image of contours of vascular structures from the first image;

    2) manipulating said probe until vascular structures of the image of said region of the body, visible in real time on said display screen, are superimposed on the displayed contours of vascular structures from the first image; and

    3) acquiring as said second image said displayed image when said superimposition is obtained, whereby the second image has substantially the same angle of incidence and inclination of the probe as the first image.
