International ClassA61B 008/00AbstractUltrasound imaging apparatus has a probe disposed on a longitudinal axis. A linear array of ultrasound transducer elements is arranged along the axis of the probe. The array is alternatively held stationary and oscillated relative to the probe about the axis between limits to define a sector. In a first mode, the transducer elements are actuated successively while the array is held stationary to generate a longitudinal rectilinear scan. In a second mode, some of the transducer elements are actuated repeatedly while the array is oscillated to generate a transverse sector scan orthogonal to the longitudinal scan. The echoes received by the transducer elements in the first and second modes are displayed as images of respective orthogonal planes. In either case, the user selects the position of the scan plane within the field of view of the array while the probe is held in a stationary position against the skin of the patient. | |
