FIELD: medical equipment.
SUBSTANCE: piezoelement for a focusing ultrasonic head is made from piezoceramics in the form of a part of a spherical cover with an angle of disclosing of 180°. In top part of a spherical cover of a piezoelement is made the flat site, its thickness coincides with thickness of part of the spherical cover, and the parity of diameter of the flat site and the diameter of part of the spherical cover makes 15-25% for provision of maximum acoustic pressure in focal maculae on resonant frequency.
EFFECT: effective focusing of acoustic emission in a zone of geometrical focus of piezoelement.
