High intensity focused ultrasound (HIFU) is rapidly gaining clinical acceptance as a
technique capable of providing non-invasive heating and ablation for a wide range of …

Numerical modeling of medical ultrasound has advanced tremendously in the past two
decades. This opens up a great number of opportunities for medical ultrasound and …

Piezoelectric ultrasonic transducers have shown great potential in biomedical applications
due to their high acoustic-to-electric conversion efficiency and large power capacity. The …

A real-time dual-mode ultrasound array (DMUA) system for imaging and therapy is
described. The system utilizes a concave (40-mm radius of curvature) 3.5 MHz, 32 element …

A series-diode linearizer scheme is developed, which can possibly generate higher voltage
signals. To verify our proposed concept, ultrasonic power amplifiers with and without the …

Purpose: Light sources such as laser and light emitting diode or ultrasound devices have
been widely used for cancer therapy and regenerative medicines, since they are more cost …

This paper describes the design and the evaluation for a simulation model for the dual
curvature ultrasound phased array. The main goal of this simulation is to enhance the usage …

A parametric study was performed to design a device capable of treating small targeted
regions within the prostate using high intensity focused ultrasound, while sparing the …

When the solid axle is detected by the conventional ultrasonic probes, the inspecting
coverage of axle is very limited, especially for the press-fit part of axle where the signal-to …

Considering the damage to normal tissues during the high-intensity focused ultrasound
ablation of the tumor is important. The purpose of this work was to design the annular array …
