Late third trimester ultrasound may detect missed fetal abnormalities

In a study published in Ultrasound in Obstetrics & Gynecology that involved more than 50,000 pregnancies, a fetal anomaly was detected for the first time in the third trimester in one in 200 women who had undergone a first and/or second trimester ultrasound examination. Most of the fetal abnormalities (68%) seen at 35 to 37 weeks had already been diagnosed […]

Ultrasound-assisted optical imaging to replace endoscopy in breakthrough discovery

Carnegie Mellon University’s Assistant Professor of Electrical and Computer Engineering (ECE) Maysam Chamanzar and ECE Ph.D. student Matteo Giuseppe Scopelliti today published research that introduces a novel technique which uses ultrasound to noninvasively take optical images through a turbid medium such as biological tissue to image body’s organs. This new method has the potential to eliminate the need for invasive […]

A miniature robot that could check colons for early signs of disease

Engineers have shown it is technically possible to guide a tiny robotic capsule inside the colon to take micro-ultrasound images. Known as a Sonopill, the device could one day replace the need for patients to undergo an endoscopic examination, where a semi-rigid scope is passed into the bowel — an invasive procedure that can be painful. Micro-ultrasound images also have […]

New microscope captures large groups of neurons in living animals: Fast, detailed imaging across a wide field of view useful for deciphering brain functions

Researchers have developed a microscope specifically for imaging large groups of interacting cells in their natural environments. The instrument provides scientists with a new tool for imaging neurons in living animals and could provide an unprecedented view into how large networks of neurons interact during various behaviors. In Optica, The Optical Society’s journal for high-impact research, researchers from Boston University, […]

Diattenuation imaging: Promising imaging technique for brain research

A new imaging method provides structural information about brain tissue that was previously difficult to access. Diattenuation Imaging (DI), developed by scientists at Forschungszentrum Jülich and the University of Groningen, allows researchers to differentiate, e.g., regions with many thin nerve fibres from regions with few thick nerve fibres. With current imaging methods, these tissue types cannot easily be distinguished. The […]
