Electronic focusing of the ultrasonic beam by means of an annular array system
In conventional mechanical contact scanners the lateral resolution is inferior to the axial one. Improving the lateral resolution over a wide range of depth requires the use of a variable focusing system. We choose the phase annular array system which may be used in obstetrics and gynaecology.
