Ultrasound generate electricity inside the body

AoS. Ultrasound generate electricity inside the body.

Implantable medical devices (IMDs) are highly beneficial to patient health. Concerning rapidly evolving technologies for IMDs, sustainable and reliable powering methods for IMDs is truly essential. They are generally relying on primary batteries, which are subject to

Compressed ultrasound imaging: finding tumors with a few transducers

Compressed Ultrasound Imaging with Holey Cavities. AoS

Currently, ultrasound imaging is predominantly done by a probe that possesses many transducers, which are small devices that transmit, and then receive, acoustic waves. Decreasing the number of transducers, while maintaining image quality, is surely a desirable

Unknown sonochemistry

The chemical effects of ultrasound, named sonochemistry, are known since 1927.  Today, there is a consensus within the scientific community that sonochemistry arises from the violent collapse of microbubbles formed in liquids submitted to power ultrasonic waves.

Looking for liver disease in babies with intestinal failure on TPN: can ultrasound replace liver biopsy?

In order to get proper nutrition to grow, a person needs to be able to use their small bowel to absorb nutrients. Some babies and children have diseases that require removal of a significant length of their

Transmitted sound wave mammography

This study was designed to look at a new type of totally harmless breast imaging called whole-breast transmission ultrasound to see if it could do something mammography cannot do – that is to diagnose the presence of

Ultrasound can help small particles penetrate into biofilms using a new oscillatory diffusion mechanism

Biofilms form when microorganisms, such as bacteria or algae, attach to a surface and surround themselves with a matrix of extracellular polymeric substance (or EPS). Biofilms are ubiquitous in nature and in a vast array of industrial

Ultrasound effect on cancerous versus non-cancerous cells

Cancer research is one of the most researched topics over the past decade. The reason for that is obvious, in 2016 alone, 1,685,210 new cancer cases and 595,690 cancer deaths are projected to occur in the United

The use of multisite ultrasound in cardiac arrest – the SESAME-protocol

Cardiac arrest is the most critical emergency. The sudden interruption of oxygen supply damages the brain after some minutes. Finding a cause for efficiently fixing the problem is the main target of the frontline physician. Ultrasound is

Utrasound-guided core-needle biopsy in thyroid nodules: 676 cases with surgical correlation

Thyroid nodules are a frequent problem. Most are benign, but up to 15% of them are malignant tumours. Ultrasound is the indicated technique to explore thyroid and search for nodules. When a nodule is discovered and it

Ultrasounds for heart infections can be reduced by following simple rules

Staphylococcus aureus bacteria often cause severe bloodstream infections, called Staph aureus bacteremia (SAB). Once Staph aureus enters the bloodstream it can spread to the heart and cause an infection of the heart valves called infective endocarditis (IE).

Ultrasound in medical education

Ultrasound is a type of energy that can be used in medicine for both making diagnoses and treating patients.   Like the sound of a voice, a person uses air passing across the vocal cords to produce noises
