Three-dimensional ultrasound imaging of the eye.

We assessed whether an inexpensive, three-dimensional (3D) ultrasound (US) imaging system could produce clinically useful 3D images, without causing patient discomfort. Five patients were examined. The 3D US system consisted of a transducer holder containing a mechanical motor, and a microcomputer. During data acquisition the transducer was mechanically rotated for 22 seconds, while 200 two-dimensional (2D) US images were collected and formed into a 3D image by the computer. The 3D image was viewed on the computer monitor. The 3D images correlated with the clinical and radiological findings. The new perspectives were helpful in diagnosing eye abnormalities and no patient discomfort occurred. The device was easy to use. It is concluded that, as good-quality 3D and 2D US images were produced quickly, with no patient discomfort, and the device is inexpensive, uncomplicated, and easily attached to existing ultrasound machines, it will probably be useful in clinical practice.
