Ultrasound Computed Tomography (USCT) is a promising complement to traditional mammography for breast cancer detection. 3D USCT systems, which allow for good illumination of the breasts, are currently limited by the long data acquisition (DAQ) times. Conventionally, sources are activated sequentially, requiring the signal to dissipate before the next wavelet is emitted. These extended DAQ...

The tissue’s speed of sound (SoS) is a promising marker for a non-invasive diagnosis of diseases such as cancer or liver steatosis. In addition, knowledge of the spatial distribution of SoS allows for aberration correction which is key for high-resolution and high-contrast photoacoustic and echo ultrasound imaging. Computed ultrasound tomography in echo mode (CUTE) retrieves spatially...

Speed-of-sound (SoS) inhomogeneities in tissue induce aberrations that degrade the quality of conventional ultrasound images. These aberrations, however, can be exploited to map the SoS, the key parameter governing wave propagation and a promising biomarker for breast cancer detection. Inspired by seismic full-waveform inversion, we present a pulse-echo SoS tomography approach with three main...

Transcranial focused ultrasound (tFUS) is advancing as a non-surgical technique for neuromodulation and tissue ablation by transmitting ultrasound waves through the skull and focusing them inside the brain. Most studies characterize ultrasound waves passing through the skull at normal incidence and for focusing at deep brain targets, while focusing on shallow brain targets and application of...

Audioplethysmography (APG) enables cardiovascular monitoring through ear-worn devices by detecting cyclical changes to the acoustic properties of the ear canal. However, body-motion-induced artifacts significantly degrade signal quality in real-world applications. This paper investigates the impact of body motion on the accuracy of APG-derived heart-rate estimates and compares a digital signal...

Rapidly producing accurate 3D spatial maps of the radiation dose distribution delivered to patients during proton therapy treatment would reduce existing beam delivery uncertainties and improve patient outcomes. Current dosimetry methods that use ionisation chambers have low spatial resolution and long acquisition times. An alternative to this would be the use of ionacoustic imaging to produce...
