Due to improved portability and patient acceptability, a recently-developed hand-held ultrasound machine has been tested in various emerging clinical applications, e.g., ambulatory healthcare. For miniaturization, in a hand-held ultrasound machine, a

We demonstrate a jitter noise reduction technique for acoustic radiation force impulse microscopy via photoacoustic detection (PA-ARFI), which promises to be capable of measuring cell mechanics. To reduce the jitter noise induced by Q-switched pulsed

We report the multiple micro-particle trapping and manipulation by a single-beam acoustic tweezer using a high-frequency array transducer. A single acoustic beam generated by a 30 MHz ultrasonic linear array transducer can entrap and transport multip

Display pixel based focusing (DPBF) can improve spatial resolution and contrast in medical ultrasound imaging. However, it suffers from increased computational complexity compared to conventional beamforming techniques. Presented is a new DPBF method
