3D scanning is all about capturing real-world data and converting it into a 3D model. Until recently, 3D scanners were mainly used for industrial applications. 3D printing is becoming more common, especially for hobbyists, and the demand for 3D scanning devices that can transform real objects into 3D printable models [...]
Phil Butler – a physicist at the University of Canterbury – along with his son, Anthony – a radiologist at the Universities of Otago and Canterbury – invented a revolutionary 3D color medical scanner known as the MARS spectral X-ray scanner. For the first time, researchers have captured 3D images [...]
From the early days of CT scanners and mammography devices, medical imaging has come a long way. With 3D medical imaging, healthcare professionals can now access new resolutions, angles, and details to help them gain a better understanding of their patient, all while cutting back on the dosage of radiation [...]
There’s a day looming on the horizon where machines powered by artificial intelligence (AI) will interpret even the most complex clinical images as accurately as today’s most experienced radiologists. […]
Imagine a microscopic machine that could unclog an artery to prevent a heart attack, or swim through one’s blood vessels to carry medicine to a cancerous tumor. Or, perhaps perform delicate vision-saving surgery from the inside of the eye. While these feats aren’t possible yet, researchers are designing miniature robots, [...]
With each new year, 3D print technology in the medical field offers greater promise across a wide range of disciplines. While the ultimate goal of printing whole, complex organs for transplants may still be decades away, 3D printing is helping to save and improve lives in ways and places never [...]
Cone-beam imaging CT (CBCT) scanners offer the advantages of being compact in size, less costly, and more portable than multidetector CT systems. Image quality, however, is often impacted by artifacts such as streaking or shading, associated with cone-beam effects and/or nonuniformity in image quality near the ends of the field-of-view [...]
With the advancements in surgical procedures, more operating rooms are performing ‘minimally invasive’ surgeries. What that means is, instead of operating on patients through large incisions, miniaturized surgical instruments are being used to fit through small, sometimes as small as quarter-inch, incisions. The surgical precision lenses in these instruments contain [...]
Sometimes known as photo eyes, photoelectric sensors emit a beam of light that is used to detect the presence or absence of items and equipment, or changes in surface conditions. When the emitted light is interrupted or reflected back by the object, the change in light patterns is measured by [...]
A photonic chip that allows a conventional microscope to work at nanoscale resolution has been developed by a team of physicists in Germany and Norway. The researchers claim that as well as opening up nanoscopy to many more people, the mass-producible optical chip also offers a much larger field of [...]
