    Abstract: An ultrasonic transesophageal scanhead is provided which enables a physician to easily and quickly change the orientation of the image plane during a scanning procedure without disrupting control of the scanhead. Means (36) are provided on the external control unit (16) of the scanhead for unambiguously selecting the orientation of the plane which is imaged by the transducers (E1L..E48T) at the end of the probe (12) of the scanhead. In one embodiment, a rocker switch (36) is provided on the underside of the control unit, and a lighted indicator (40) is provided on top of the control unit. When the physician desires to change the image plane, the rocker switch is rolled forward to select the transducer elements (E1L..E48L; E1T..E48T) of the probe which are configured for scanning in the desired image plane. As the rocker switch is moved, the lighted indicator (40) on the top of the control unit provides a visual display pattern aligned either longitudinally (40b, 40c) or transversely (40a, 40b) with respect to the axis of the probe. Thus, the physician can change scanning planes without moving his hand from the control unit, and the unit constantly provides an indication of the orientation of the selected plane.
