Cardiac ultrasound imaging goes to handheld
Cardiac ultrasound imaging, also known as echocardiography, has been recently challenged by several new imaging methods. view more (2008-09-02)
Thermal imaging shatters arousal gender gap myth
A new McGill University study that used thermal imaging technology for the first time ever to measure sexual arousal rates has turned the conventional wisdom that women become aroused more slowly than men on its head. view more (2006-10-02)
Cancer cells forming blood vessels send their copper to the edge
New information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies has been discovered by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago, using a beamline at the Advanced Photon Source. view more (2007-02-28)
MR imaging helps predict recurrence in prostate cancer patients
MR images taken of prostate cancer patients prior to treatment that show that the cancer has spread outside the prostate gland capsule help predict whether the cancer will return. view more (2007-05-07)
Patients with PTSD experience less pain sensitivity — may be related to altered processing
Patients with posttraumatic stress disorder show reduced pain sensitivity, a pattern that may be related to altered pain processing in the brain. view more (2007-01-02)
Imaging technique may prevent injury during ablation for atrial fibrillation
A new imaging procedure may reduce the risk of esophageal injury in patients undergoing catheter ablation for atrial fibrillation (AF), according to a study published in the September 2006 edition of Heart Rhythm. view more (2006-08-23)
New MRI technique quickly builds 3-D images of knees
A faster magnetic resonance imaging (MRI) data-acquisition technique will cut the time many patients spend in a cramped magnetic resonance scanner, yet deliver more precise 3-D images of their bodies. view more (2006-07-27)
Image processing for applications in artificial vision
For a robot to identify objects in a particular image, it is first necessary that it can "see" them. With this aim, in artificial vision, edge detectors are normally used, i.e. computer programmes that delimit the objects in an image and define the limits between them and the background, and between the different objects themselves. view more (2006-01-17)
CT and ultrasound equally valuable in diagnosing pelvic pain in women
CT and ultrasound are both valuable first-line cross-sectional imaging tools to detect the cause of acute pelvic pain in non-pregnant women and the need for surgery in these patients, according to a new study by researchers from the University of Washington Harborview Medical Center in Seattle, WA. view more (2006-05-01)
SMART-1 uses new imaging technique in lunar orbit
ESA's SMART-1 spacecraft has been surveying the Moon's surface in visible and near-infrared light using a new technique, never before tried in lunar orbit. view more (2005-12-27)
NASA's Cassini images reveal spectacular evidence of an active moon
Jets of fine, icy particles streaming from Saturn's moon Enceladus were captured in recent images from NASA's Cassini spacecraft. The images provide unambiguous visual evidence the moon is geologically active. view more (2005-12-07)
Rein for pain lays mainly in the brain, Stanford researchers find
Chronic pain sufferers may be able to reduce pain levels by studying their own live brain images, researchers at the Stanford University School of Medicine report in a new study. view more (2005-12-13)
NIST math technique opens clearer window on universe
A fast, efficient image enhancement technique developed at the National Institute of Standards and Technology (NIST) and originally applied to improving monochrome microscope images has proved itself equally effective at the other end of the scale- sharpening details on color images of distant galaxies produced by the Hubble Space Telescope. view more (2006-12-11)
New research explores limits of non-invasive coronary imaging tests
If multi-slice computed tomography (MSCT) shows that a patient has plaque build-up in the artery walls, does it also mean that there is actual reduced blood flow in the artery\\\ view more (2006-12-12)
New sonofusion experiment produces results without external neutron source
A team of researchers from Rensselaer Polytechnic Institute, Purdue University, and the Russian Academy of Sciences has used sound waves to induce nuclear fusion without the need for an external neutron source. view more (2006-01-30)
New quantum dot transistor counts individual photons
A transistor containing quantum dots that can count individual photons (the smallest particles of light) has been designed and demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-10-12)
18F-DG PET/CT can highly increase the detection of colorectal cancer
Combined positron emission tomography and computed tomography (PET/CT) is currently widely used in the clinical diagnosis of cancer to provide functional and morphological imaging. view more (2007-10-11)
Whole-body scans may provide option for diagnosing colorectal cancer
Preliminary research suggests that whole-body PET and CT scans could provide a suitable method for diagnosing the stage of colorectal cancer, according to a study in the December 6 issue of JAMA. view more (2006-12-06)
New study finds PET imaging value in tracking diabetes progression
"Diabetes is the only major disease with a death rate that continues to be on the upswing," proclaimed a front-page New York Times story this week. view more (2006-05-19)
PET accurately identifies esophageal cancer patients' positive responses to chemotherapy
Early metabolic imaging with positron emission tomography (PET) accurately identifies patients responding to chemotherapy for esophageal cancer, noted German researchers at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals. view more (2007-06-04)
