AI Spots Lung Cancer Before Radiologists

  • Magazine Article
  • TBMG-34813
Published 2019-07-01 by Tech Briefs Media Group in United States

Deep learning — a form of artificial intelligence — was able to detect malignant lung nodules on low-dose chest computed tomography (LDCT) scans with a performance meeting or exceeding that of expert radiologists.

 

Using Data-Centric Connectivity to Drive Innovation in Medical Imaging

  • Magazine Article
  • TBMG-34798
Published 2019-07-01 by Tech Briefs Media Group in United States

Today's imaging systems save lives by making the unseen visible to a degree never before possible. Medical professionals can now view systems within the human body in high resolution, enabling them to diagnose pathological changes while precisely targeting therapeutic procedures. From the operating room to telemedicine, these imaging technologies play a key role in the future of medical diagnostics and therapeutics.

 

3D Printed Device Detects Biomarkers of Preterm Birth

  • Magazine Article

Published 2019-07-01 by Tech Briefs Media Group in United States

Researchers have created a 3D printed microchip electrophoresis device that can sensitively detect three serum biomarkers of PTB.

 

New Technique Tests for Viral Infections

  • Magazine Article
  • TBMG-34756
Published 2019-07-01 by Tech Briefs Media Group in United States

Currently, most U.S. medical offices and hospitals use the ELISA (enzyme-linked immunosorbent assay) test to determine whether or not a person has a viral infection. It’s a common test but ELISA’s sensitivity is relatively low, so clinicians need a fairly high number of antibodies in a person’s blood to get a positive test result. It also often takes seven to 10 days after an infection for the test to register.

 

Q&A: 3D-Printed Hydrogel Blocks Can Aid Robotics and Diagnostics

  • Magazine Article
  • TBMG-34631
Published 2019-06-01 by Tech Briefs Media Group in United States

Ian Y. Wong, Ph.D., is Assistant Professor of Engineering, Molecular Pharmacology, Physiology and Biotechnology at Brown University in Providence, RI. He and colleagues have developed a new type of hydrogel blocks that can be assembled like LEGO®s.

 

Spotting Minute Amounts of Disease in the Bloodstream

  • Magazine Article
  • TBMG-34586
Published 2019-06-01 by Tech Briefs Media Group in United States

The difficulty in spotting minute amounts of disease circulating in the bloodstream has proven a stumbling block in the detection and treatment of cancers that advance stealthily with few symptoms. With a novel electrochemical biosensing device that identifies the tiniest signals these biomarkers emit, a pair of NJIT inventors are hoping to bridge this gap. There could therefore be a simple, inexpensive test performed at a regular patient visit in the absence of specific symptoms to screen for some of the more silent, deadly cancers — to have a nanotechnology-enhanced biochip to detect cancers, malaria, and viral diseases such as pneumonia early in their progression, with a pin prick blood test.

 

Materials Matter for Connected Health

  • Magazine Article
  • TBMG-34550
Published 2019-06-01 by Tech Briefs Media Group in United States

Technology has always played a central role in healthcare. From microscopes to medical imaging, and from pacemakers to prosthetics, technological breakthroughs throughout history have improved diagnosis, prevention, treatment, and rehabilitation.

 

Earlier Detection of Diabetic Retinopathy with Smartphone ArtificiaI Intelligence

  • Magazine Article
  • TBMG-34558
Published 2019-06-01 by Tech Briefs Media Group in United States

A novel pairing of two technologies may offer a solution for better screening for diabetic retinopathy, a condition that can lead to permanent vision loss if not caught early. Combining a smartphone-mounted device that takes high-quality retinal pictures with artificial intelligence software that reads them can determine in real time whether a patient should be referred to an ophthalmologist for follow up.

 

Modular Blocks Enable Plug-and-Play Diagnostic Devices

  • Magazine Article
  • TBMG-34604
Published 2019-06-01 by Tech Briefs Media Group in United States

Over the past decade, many researchers have been working on small, portable diagnostic devices based on chemical reactions that occur on paper strips. Many of these tests make use of lateral flow technology, which is the same approach used in home pregnancy tests.

 

Detect Ultra Rare Proteins in Blood Using a Cellphone Camera

  • Magazine Article
  • TBMG-34418
Published 2019-05-01 by Tech Briefs Media Group in United States

One of the frontiers of medical diagnostics is the race for more sensitive blood tests. The ability to detect extremely rare proteins could make a life-saving difference for many conditions, such as the early detection of certain cancers or the diagnosis of traumatic brain injury, where the relevant bio-markers only appear in vanishingly small quantities. Commercial approaches to ultrasensitive protein detection are starting to become available, but they are based on expensive optics and fluid handlers, which make them relatively bulky and expensive and constrain their use to laboratory settings.
