Researchers developed a new scanning method that combines light and ultrasound to non-invasively monitor cerebrovascular changes in the early stages of an ischemic stroke in real time.
Stiffness in tissues can be a valuable indicator of cancer formation. Now, researchers have developed a microscopic probe to perform histology at the single cell level inside the human body.
Using AI and optoacoustic imaging, researchers have developed a new method to assess microvascular changes in the skin – and thus the severity of diabetes in the patient.
Researchers and clinicians at Washington University in St. Louis found a way to improve diagnostic accuracy of potentially cancerous lesions in the ovaries and adnexal regions, or the fallopian tubes.
Engineers have developed an electronic patch that can give medical professionals unprecedented access to crucial information that could help spot life-threatening conditions.
Recently, a Korean research team has developed a 3D foot imaging technique that vividly captures peripheral blood vessels, even thinner than 1 mm. It combines photoacoustic and ultrasound images.
Researchers at Helmholtz Zentrum München and the Technical University of Munich (TUM) have developed the world’s smallest ultrasound detector. It is based on miniaturized photonic circuits on top of a silicon chip. With a size 100 times smaller than an average human hair, the new detector can visualize features that are much smaller than previously possible, leading to what is known as…
A new, portable breast imaging system under development in Buffalo has the potential to better identify breast cancer in women with dense breast tissue. That is among the findings of a study published in the journal IEEE Transactions on Biomedical Engineering. The study was led by University at Buffalo researchers in collaboration with Roswell Park Comprehensive Cancer Center and Windsong…
Cancer treatment could be dramatically improved by an invention at the University of Waterloo to precisely locate the edges of tumors during surgery to remove them.
Targeting medical treatment to an ailing body part is a practice as old as medicine itself. A Band-Aid is placed on a skinned knee. Drops go into itchy eyes. A broken arm goes into a cast. But often what ails us is inside the body and is not so easy to reach. In such cases, a treatment like surgery or chemotherapy might be called for. A pair of researchers in Caltech's Division of Engineering and…
Determining where breast cancer ends and healthy tissue begins is a critical part of breast cancer surgery. Surgeons are used to working closely during surgery with anatomic pathologists who generate pathology reports that specify the surgical or tumor margin, an area of healthy tissue surrounding a tumor that also must be excised to ensure none of the tumor is left behind. This helps prevent the…
Automation continues to conquer healthcare, including diagnostic imaging. Christian Kollmann, Assistant Professor at the Centre for Medical Physics and Biomedical Technology, Medical University Vienna, Austria, highlights innovative software, fast hardware and artificial intelligence in ultrasound – today and in the future. Automated analyses are already supporting the diagnostic work-up. In…
Of the quarter-million women diagnosed with breast cancer every year in the United States, about 180,000 undergo surgery to remove the cancerous tissue while preserving as much healthy breast tissue as possible. However, there’s no accurate method to tell during surgery whether all of the cancerous tissue has been successfully removed.
While active surveillance is often recommended for patients with nonaggressive prostate cancer to reduce unnecessary treatment, the challenge for clinicians is to monitor and distinguish early-stage tumors from advanced cancers. A team of scientists led by researchers from Roswell Park Cancer Institute have demonstrated that photoacoustic imaging (PAI) may be an effective tool for more accurately…
For the examination of coronary blood vessels, intravascular methods with imaging technologies are already state-of-the-art. However, ultrasonic methods, which are used to gather information about the tissue, can only be used externally, up to now. The piezo electronical components necessary for this have not been sufficiently miniaturized to be inserted into the blood vessels.
An organic dye that can light up cancer cells for two powerful imaging techniques providing complementary diagnostic information has been developed and successfully tested in mice by A*STAR researchers.
The view across the Atlantic – it fills Professor Fabian Kiessling, Chair of Experimental Molecular Imaging at the RWTH Aachen (Rhine-Westphalia Institute of Technology Aachen), with optimism. The USA offers more opportunities for molecular imaging. Only recently, new tracers for Alzheimer’s were accepted as reimbursable in some centres, whilst the development of new diagnostics in Europe…
Photoacoustics offers an additional contrast mechanism that makes the technology far more sensitive for the presence of blood.
Mammography is the common way to detect breast cancer. But it's not perfect: it struggles to image dense glandular tissue or early-stage tumours. Magnetic resonance imaging (MRI) offers best sensivity but it is expensiv and not always specific enough. Now researchers have come up with another option: a scanner that integrates thermoacoustic and photoacoustic tomography to achieve dual-contrast…
