## Abstract ## Purpose. To explore the feasability of imaging lung masses with a novel endobronchial linearβarray transducer. ## Method. We used a linearβarray transducer of 7 F (2.3 mm in diameter) operating at a center frequency of 10 MHz for endobronchial imaging. We used the probe in 20 subj

β¦ Synopsis
Continuous observation of fetal movement patterns is a novel and useful capability of new high-speed ultrasound imaging systems. Confirmatory documentation of human fetal breathing as a component of these movement patterns has been achieved using a phased-array real time ultrasound sector scanning system. This system permits direct visualization of fetal breathing movements. Permanent recordings can be made on videotape. Recordings can also be made as a time-motion echocardiograms during continuous observation of the full sector. Fetal breathing movements were seen in five patients. The earliest period of gestation at which fetal breathing was seen was 20 weeks.

We prospectively compared standard resolution and high resolution breath-hold T1-and T2-weighted images of the upper abdomen with use of a body phased-array multicoil in 30 patients. The image quality of high resolution T1-weighted FLASH sequence was equal to that of standard resolution sequence, wh
The aim of this study was to test a prototype MRI-compatible focused ultrasound phased array system for trans-skull brain tissue ablation. Rabbit thigh muscle and brain were sonicated with a prototype, hemispherical 500-element ultrasound phased array operating at frequencies of 700-800 kHz. An ex v
