ABSTRACT:
An ultrasound apparatus for imaging tissues from interior of a cavity in the body of a patient is disclosed. The apparatus includes a probe for entering the body to the cavity. The probe has a distal end for entering the body and a proximal end to extend outside the body. At the distal end of the probe is a transducer associated with a rotatable mechanism for transmitting sequential ultrasonic pulses as the rotatable mechanism rotates, forming an angular pattern of transmitted pulses. Ultrasonic energy reflected and scattered from the patient's body tissues is received by an transducer so that each pulse generates a received signal (RF-line). The apparatus has a mechanism for identifying the angular separation between the RF-lines by analyzing the RF-lines caused by reflection and scattering by the body tissues alone. In this way, any distortion caused by the difference between the transmitted angular pattern and the intended angular pattern, if present, can be determined and corrected.
