Claim:
1. An ultrasonic scanning system, comprising: an instrument body to engage a patient and position a head and an eye of the patient; and a positioner assembly connected to the instrument body, the positioner assembly comprising a scan head assembly, which comprises at least one guide track, at least one transducer carriage and at least one ultrasound transducer, wherein the at least one transducer carriage moves along the at least one guide track; wherein the at least one ultrasound transducer is mounted on the at least one transducer carriage, and the at least one ultrasound transducer emits an ultrasound pulse and receives an ultrasound pulse reflected from one or more components of the patient's eye when the patient is engaged with the instrument body; and at least one ultrasound position sensor fixed relative to the positioner assembly, wherein the at least one ultrasound position sensor measures a position of the patient's eye relative to at least one of an eye socket, the instrument body, and the positioner assembly using an eye fiducial, wherein a computer processor is configured to alter, using the measurement of the position of the patient's eye, a recorded position in a coordinate system of individual ultrasound pulses in the received ultrasound pulses reflected from the one or more components of the patient's eye to account for movement of the patient's eye during ultrasound pulse emission and/or reception, and wherein the computer processor is configured to construct an ultrasound image of the patient's eye based on the received ultrasound pulses and the corresponding, altered positions in the coordinate system.
