An ultrasonic scanning apparatus that includes a unique ultrasonic array to transmit ultrasonic energy to a biological structure, such as an eye. The ultrasonic array provides specific three-dimensional (3-D) information relating to the eye and precise volumetric information relating to structures associated therewith, such as a tumor, prior, during and/or after treatment. The ultrasonic array can also be combined with a therapeutic ultrasonic unit for real-time 3-D observation of a structure and the focal point of the transmitted therapeutic beam(s) on a monitor during the treatment of a structure, e.g., treatment of a lesion.
