Tiny lensless endoscope captures 3D images of objects smaller than a cell: Self-calibrating technology opens new opportunities for medicine and research

Researchers have developed a new self-calibrating endoscope that produces 3D images of objects smaller than a single cell. Without a lens or any optical, electrical or mechanical components, the tip of the endoscope measures just 200 microns across, about the width of a few human hairs twisted together. As a minimally invasive tool for imaging features inside living tissues, the […]

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, […]

Imaging technique finds differences between radiation-sensitive and resistant tumors: Pilot clinical trials begun

Researchers have started pilot clinical studies in head and neck cancer patients to determine if Raman spectroscopy, a noninvasive imaging technique, can effectively spare some patients of the toxic side effects of ineffective radiation therapy. Researchers at the University of Arkansas, Johns Hopkins University and the University of Arkansas for Medical Sciences (UAMS) used the imaging technique and discovered differences […]

Improving IVF success rates

Faster, cheaper and less damaging to DNA, a microchip device that pits sperm racing against one another is being developed by Afrouz Ataei from Florida Atlantic University and may help to improve IVF success rates in the future. Ataei is presenting the fitness stats on the sperm sorted by her device this week at the American Physical Society March Meeting […]

Going for an MRI scan with tattoos? First prospective study on risk assessment

According to Weiskopf, Director at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig (MPI CBS), .” ..the most important questions for us were: Can we conduct our studies with tattooed subjects without hesitation? What restrictions may exist? At the Wellcome Centre for Human Neuroimaging, part of Queen Square Institute of Neurology at University College in London, […]
