Tissue harmonic synthetic aperture ultrasound imaging.
Synthetic aperture sequential beamforming (SASB) and tissue harmonic imaging (THI) are combined to improve the image quality of medical ultrasound imaging. The technique is evaluated in a comparative study against dynamic receive focusing (DRF). The objective is to investigate if SASB combined with THI improves the image quality compared to DRF-THI. The major benefit of SASB is a reduced bandwi...
متن کاملbetter visualization of vermiform appendix with tissue harmonic imaging compared to conventional sonography
conclusions thi visualizes appendix better than conventional us. it is a simple and time saving method that may eliminate further diagnostic imaging, and it may decrease negative appendectomy rates and related complications. patients and methods the study was performed on 185 patients who applied for routine us examinations in whom clinical findings of appendicitis were detected in 25. we searc...
متن کاملUltrasound guidance improves a continuous popliteal sciatic nerve block when compared with nerve stimulation.
BACKGROUND AND OBJECTIVES Continuous sciatic nerve blockade at the popliteal level effectively alleviates postoperative pain after major foot and ankle surgery. No randomized controlled trials have previously compared the success rate of continuous sciatic nerve sensory blockade between ultrasound and nerve stimulation guidance. In the current study, we tested the hypothesis that ultrasound-gui...
متن کاملCoded Excitation Methods for Ultrasound Harmonic Imaging
Coded excitation methods offer the potential for improving the SNR without increasing the peak transmitted power and without sacrificing resolution. Our study examines the potential application of coded waveforms, specifically FM chirps, in harmonic imaging. Such a system, in which nonlinear echoes from tissue are used to form the image, requires the extraction and compression of the second har...
متن کاملHarmonic imaging of the human brain. Visualization of brain perfusion with ultrasound.
BACKGROUND AND PURPOSE Through harmonic gray-scale imaging, it is possible to analyze brain tissue perfusion with different ultrasound methods. METHODS In 12 healthy volunteers, 2 doses (0.5 and 1.5 mL) of Optison, a perfluoropropane-containing contrast agent, were injected intravenously and produced a strong increase of brightness in the brain parenchyma. We used harmonic imaging for quantif...
