Minimally-compressive, three- and four-dimensional ultrasound imaging of the clitoris: a feasibility study.

There has been no objective means for imaging the three-dimensional (3D) morphology of the clitoris-a poorly understood, complex structure. A Live 3D ultrasound system with a matrix-array transducer was used for data acquisition from eight women. The transducer was positioned in front of and about 3 cm away from the clitoris, with a gel pad or water pad being placed in between.

Real-time three-dimensional ultrasound visualization of erection and artificial coitus.

To investigate the feasibility of imaging penile erection and coitus in real time and in three dimensions, a 'Live' three-dimensional (3-D) ultrasound system was used to acquire the volume of interest at 25 Hz from five healthy men. Water baths and gel-made artificial vaginas were devised to facilitate the 3-D scans without the probe being in direct contact with the penis. For the first volunteer scanned with the water bath alone, the penis failed to erect within 30 min.

Real-time three-dimensional fetal echocardiography--optimal imaging windows.

A total of 15 fetuses were scanned using 2-D array volumetric ultrasound (US). Acquired cardiac data were converted for rendering dynamic 3-D surface views and reformatting cross-sectional views. The image usefulness was compared between the data obtained from subcostal/subxiphoid and other imaging windows; the former are usually free of acoustic shadowing.
