Small-organ dynamic imaging system

Dynamic ultrasonic imaging of superficial body organs adds a new dimension to clinical sonographic examinations in that it enables the real-time evaluation of tissue motion and vascular pulsations. A high-frequency (7.2 MHz) linear-array system has been newly developed that generates simultaneous A- and B-mode displays at 60 frames/sec. The instrument produces real-time scan-converted images in standard television format for direct viewing on television (TV) monitors or clinical recording through videotape equipment. Clinical application of this dynamic imaging system has increased the diagnostic capabilities of ultrasound in ophthalmology, radiology, and pediatrics.
