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.

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.

 

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.

 

Imaging System Helps Surgeons Remove Tiny Ovarian Tumors

  • Magazine Article
  • TBMG-34569
Published 2019-06-01 by Tech Briefs Media Group in United States

Ovarian cancer is usually diagnosed only after it has reached an advanced stage, with many tumors spread throughout the abdomen. Most patients undergo surgery to remove as many of these tumors as possible, but because some are so small and widespread, it is difficult to eradicate all of them.

 

Full-Spectrum Infrasonic Stethoscope for Screening Heart, Carotid Artery, and Lung-Related Diseases

  • Magazine Article
  • TBMG-34619
Published 2019-06-01 by Tech Briefs Media Group in United States

Microphones and stethoscopes are regularly used by physicians to detect sounds when monitoring physiological conditions. These monitors are coupled directly to a person's body and measure in certain bandwidths either by listening or by recording the signals. The physiological processes, such as respiration and cardiac activity, are reflected in a different frequency bandwidth from 0.01 Hz to 500 Hz.

 

UCI Biomedical Engineers Develop Wearable Respiration Monitor with Children’s Toy

  • Magazine Article
  • TBMG-34583
Published 2019-06-01 by Tech Briefs Media Group in United States

Researchers at the University of California, Irvine have developed a wearable, disposable respiration monitor that provides high-fidelity readings on a continuous basis. It’s designed to help children with asthma and cystic fibrosis and others with chronic pulmonary conditions.

 

Force-Sensitive Innovations: Addressing Cerebral Palsy Challenges with Electronic Medical Training Devices

  • Magazine Article
  • TBMG-34559
Published 2019-06-01 by Tech Briefs Media Group in United States

Nine years ago, Julian Gunderson was born three months prematurely and weighed just 1 kg (2.2 lb). After a year's worth of injections, medications, transfusions, and other treatments, doctors diagnosed Julian with cerebral palsy.
