Abstract
An ultrasound diagnosis apparatus that can acquire ultrasound image data having excellent spatial resolution and contrast resolution by electrically controlling focusing points of transmission/reception waves so as to form transmitting beams and receiving beams having substantially uniform thin beam width along an elevation direction. Ultrasounds emitted from a prescribed number of transducers are focused at a hypothetical point sound source. Wave-fronts reflect at a plurality of observing points. Ultrasounds reflected at the observing points are received through a prescribed number of transducers generating a plurality of channels of receiving signals, which are focused by performing phase compensation and summation so that the observing point becomes a reception focusing point. The receiving signals are focused to correct transmitting delays due to propagation distances between the transmitting focusing point and the observing points.
