A method for displaying scanned ultrasound images of tissue employs an apparatus including an ultrasound probe mounted to a mechanical head. A three-dimensional positioning system mounts the head for positioning the probe in proximate orthogonal relation to the tissue. A computer controls the three-dimensional positioning system thereby moving the probe during a scan. The probe transmits high frequency ultrasound waves whose nominal frequency is included within the range from 30 to 100 MHz and with a large pass band, adapted to frequencies reflected by the tissue. The beams of ultrasound transmission are focused in a given zone of the tissue over a vertical penetration distance of between 20 and 30 mm. Reflected signals are acquired and processed for display.

The scanning system of the invention includes a structure driven in rotation around a first axis, a structuremounted rotating on the structure around an axis parallel to the first axis, a structure for supporting an echographic probe mounted rotating on the structure around a third axis parallel to the axis, a coupling element between the structure and the structure and a coupling element between the support structure and the structure. This system being able to move the probe along a variable band arciform trajectory.
