Abstract
A device for positioning an energy-generating transducer probe a movement unit. The transducer probe may be configured for heat treatment of biological tissues and emits energy in one aiming direction which is located in an aiming plane. The movement unit is configured to alter the position of the transducer probe and, consequently, the aiming direction in the aiming plane around a target zone within the aiming plane.
Claims19
An assembly for heat treatment of a breast of a patient, comprising:
- an ultrasonic transducer configured to emit energy in an aiming direction included in an aiming plane;
- and
- a platform configured to maintain a body of the patient in a position in which a coronal plane of the body of the patient extends approximately parallel to the aiming direction while the breast of the patient cuts across the aiming direction;
- a bed;
- and
- a positioner that includes a frame that supports the ultrasonic transducer, the positioner further including a mechanical movement unit having movable rods extending along a length of the bed and movable guide rails extending across the bed, the movable rods being approximately parallel to the coronal plane of the body,
- wherein a first movable rod of the movable rods is configured to move the ultrasonic transducer along the length of the bed and across the bed,
- wherein a second movable rod of the movable rods is configured to rotate the ultrasonic transducer for rotating the aiming plane around a rotation axis extending through the coronal plane of the body,
- wherein a third of the movable rods is configured to tilt the aiming plane with respect to the coronal plane, and
- wherein a portion of two of the first, second and third movable rods are directly coupled to the frame.
