High-resolution ultrasonic imaging and characterization of the ciliary body.

摘要: PURPOSE. To develop a means for noninvasive in vivo visualization of the ciliary processes using very-high-frequency (50 MHz) ultrasound and to quantitative morphologic descriptors that may relate physiologic function. METHODS. The region body was scanned with ultrasound, both rabbits normal human subjects. Data were acquired series planes so spacing between them less than beam width transducer its focal plane. Three-dimensional perspective images constructed, representing anatomy angle region, including processes. automatically detected boundaries analyzed compute their periphery, area, shape factor, fractal dimension. These measures compared rabbit eye periodicities related successive RESULTS. allowed radial arrangement All biometric significantly different showed consistent CONCLUSIONS. methods described this report are sensitive state techniques be value measurement changes associated disease, medical therapy, aging.
