Breast cancer has surpassed lung cancer as the leading cause of global cancer incidence in 2020. Traditional handheld 2D ultrasound imaging is one of the major imaging tools for breast cancer screening in China. Compared with the traditional method, ultrasound tomography (UST) provides three-dimensional reproducible images of higher quality, simplifying and standardizing the image acquisition...

To emit short broadband pulses, piezoelectric transducers require a high acoustic impedance, highly attenuating backing material that reduces backside reflections. The current generation of Transducer Array Systems (TAS 3.0) for the KIT 3D USCT III device uses a polyurethane-tungsten composite backing. Although this backing exhibits significant acoustic attenuation, some drawbacks are its...

field of medical imaging, particularly through the application of ultrasound localization
microscopy (ULM). However, ULM's requires sparse microbubble distributions, which in
turn, imposes prolonged acquisition times to adequately image the full
microvasculature. We introduce a novel super-resolution methodology... -

Motivation
The KIT 3D ultrasound computertomography project is kickstarting the build up of a second machine of the 3D USCT III device generation, called v3.2. Extensive experience with their successfully commissioned device v3.1 regarding mechanical and handling properties were aquired over the last month and years: integration, maintainance, updates, transport tasks, many test...

All medical electrical equipment generates electromagnetic radiated disturbances, and the emission levels should comply with the limits required by relevant standards to protect the public radio services in the electromagnetic environment where they are located. Existing international standards only provide general methods and basic principles for measuring radiated emission. For ultrasound...

Photoacoustic tomography (PAT) is a biomedical imaging technique utilising the photoacoustic effect that can be induced by an external light pulse. The aim in PAT is to reconstruct an initial pressure distribution that has been generated in the target by illumination of light. This is carried out by measuring the propagating pressure waves on the boundary of the target, and performing a...

Full-waveform inversion (FWI) is a powerful reconstruction technique to generate high-resolution models of tissue and bone structure using non-invasive ultrasonic measurements. Sound-speed and reflectivity distributions within the tissue are reconstructed via an iterative data-fitting procedure that models the non-linear relationship between the ultrasonic wavefield and the model parameters....

Background
Go to contribution page
In brain ultrasound imaging, the high impedance barrier presented by the skull is a significant challenge, as it impedes the transmission of acoustic waves into the skull interior. To address this issue, the utilization of a Fabry-Perot resonance-tailoring panel (RTP) placed in front of the skull can be employed to enhance sound wave transmission through the skull by...
