Researchers at the University of Connecticut have developed a lensless microscope that allows an observer to enjoy an enormous field of view. Instead of a lens, the system relies on a diffuser that lies between the object being imaged and the camera sensor. This novel technology could greatly help clinicians to assess diagnostic tissue samples [&he (Read more...)

Smart Jumpsuit Tracks Infant Movements to Spot Neurodevelopmental Disorders
Researchers at the University of Helsinki have developed a smart jumpsuit for children as young as five months, that tracks body movement in great detail. The system may allow clinicians to identify neurodevelopmental disorders in children more easily, potentially allowing for earlier intervention and support for such children. At present, assessin (Read more...)
QyScore Analyzes MRIs for Biomarkers of Brain Diseases
Qynapse, a firm headquartered in Paris, France, won FDA clearance for its QyScore software that analyzes brain MRIs for biomarkers of central nervous system diseases. It’s intended to help diagnose and monitor diseases such as Alzheimer’s, Parkinson’s, and multiple sclerosis, though it doesn’t do it on its own. The technolog (Read more...)
Smartphone With Laser and Thermal Cameras to Screen Passersby for Fever
The current coronavirus infecting thousands of people in China (COVID-19) is making public health authorities around the world responsible for screening millions of people going through airports, returning from cruises, and crossing borders by land. The number one tool is the thermometer and checking is usually done by placing it against the forehe (Read more...)
First AI-Guided Ultrasound Gets Green Light from FDA
Caption Health, a company based outside of San Francisco, CA, won the first authorization from the FDA for an ultrasound software that guides clinicians at capturing images of the heart. The Caption Guidance software should work with any number of ultrasound system from different manufacturers, but currently it can only be used with a diagnostic [& (Read more...)
BioSticker FDA Cleared for Month-Long Vitals Monitoring
BioIntelliSense, a Silicon Valley firm, won FDA clearance for its BioSticker wearable sensor and the company is also releasing its Data-as-a-Service platform. The BioSticker can track heart rate, respiratory rate, skin temperature, body position, sleep status, and activity levels, as well as provide a high-resolution gait analysis, fall detection, (Read more...)
Credit Card Sized Diagnostic Lab Plugs into Smartphone
Researchers at the University of Cincinnati have developed a tiny portable diagnostic device that can detect the presence of specific pathogens in a saliva sample, and relay the results to a doctor when plugged into a smartphone. The device can potentially diagnose a wide array of diseases, including malaria, HIV and Lyme disease, and could [&helli (Read more...)
Plasma Protein Levitation Technique Could Provide New Diagnostic Tool
Researchers at Michigan State University have developed a technique to levitate plasma proteins using a magnetic field. The technique provides very accurate information on the density of the proteins, and could reveal signatures of disease, potentially allowing clinicians to diagnose various conditions, such as multiple sclerosis, more easily. The (Read more...)
Portable Nanoplasmonic Imager Detects Sepsis Biomarkers
Sepsis is an incredibly dangerous condition, typically occurring within hospitals. According to a recent study nearly 20% of all deaths worldwide are caused by sepsis, as it is a disease that quickly gets out of control if not treated early and properly. At present, there is no easy way for clinicians to quickly provide a […]
Magnetized Particles Show Live Metabolic Activity of Breast Cancer
Current imaging methods that are used to spot tumors don’t provide much information about the rate of activity of the cells making up the diseased tissues. Breast cancer tumors, for example, are mostly classified into a few categories based on hormone receptor and HER2 expression. Researchers at Cancer Research UK Cambridge Institute and the (Read more...)
Smartphone Camera Test for Urinary Tract Infections
Researchers at the University of Bath have developed a simple point-of-care test for urinary tract infections that uses a smartphone camera. The system can rapidly detect the presence of E. coli in urine samples and could guide doctors in their decision to prescribe antibiotics, ensuring appropriate patient care and avoiding the overuse of antimicr (Read more...)
Body Sensors Made of Magical Self-Healing Threads
A team of scientists in South Korea has developed a remarkable new body sensor technology that consists of flexible threads that can heal on their own. The fabric-like threads, which are made of carbon fiber electrodes coated with a citric acid-based polymer, can measure electrolyte concentrations within sweat. The team used their material, which a (Read more...)
Laser Ultrasound System Images People’s Insides from a Distance
Clinical non-invasive ultrasounds require their transducers to make contact with the skin, as that allows high frequency vibrations to travel through the body. Many patients, including children, people with burns, and those with sensitive skin would rather be scanned using a contact-free system. Researchers at MIT have now shown that it is indeed p (Read more...)
Sensor Chip Screens Urine for Cancer Biomarker
Researchers from a multi-institutional group have developed a label-free chip-based sensor to detect very low levels of a cancer biomarker in urine. This exciting development may one day help catch cancer earlier, perhaps during regular screenings, leading to better outcomes. Current methods of cancer biomarker detection are often expensive and cha (Read more...)
Canon Unveils Aquilion ONE / PRISM Edition Spectral CT Scanner
At the RSNA 2019 conference in Chicago, Canon Medical showed off its brand new Aquilion ONE / PRISM Edition spectral CT scanner, a system that takes advantage of artificial intelligence technologies. The device relies on Canon’s Advanced intelligent Clear IQ Engine (AiCE) along with its Deep Learning Spectral Reconstruction imaging algorithms (Read more...)
DNA Nanoarchitecture Used to Construct Dengue Fever Virus Traps
Dengue fever is spread by mosquitoes that carry the Dengue virus. Early detection of an infection is important, but currently it is difficult to achieve in the field. Moreover, treatment options are limited and blood transfusions are required to save many patients. Researchers at Rensselaer Polytechnic Institute have now employed “DNA nanoarc (Read more...)
Optical Coherence Tomography Finally Used to Measure Cartilage Health
Optical coherence tomography (OCT) is an imaging modality that provides a micron-level look at the tissues being examined. It is used in ophthalmology to assess the eyes and for imaging the interior of arteries to help with atherectomies. Although OCT has significant potential to help clinicians evaluate the health of tissues, it has proven difficu (Read more...)
AI Diagnoses Leukemia from Blood Samples as Well as Human Cytologists
A good deal of clinical diagnostics are effectively performed by cytologists who examine cells through a microscope for signs of disease. This is an imperfect, slow process that depends on the training, focus, and attention to detail of the cytologist. Now, researchers at Helmholtz Zentrum München and the University Hospital of LMU Munich in G (Read more...)
Novel Coating Makes Affinity-Based Sensors Practical for Medicine
Affinity-based sensors are electrochemical devices that can detect a large variety of disease biomarkers. They typically have enzyme-coated electrodes onto which chemical biomarkers can stick, in the process changing the electrical characteristics of the device, something that can be accurately measured. Although they’re extremely sensitive, (Read more...)
