In arc therapy, a linear accelerator gantry moves in a continuous arc around the target while delivering radiation dose. Patients have been routinely treated with this technology since the 1980s, when it was put into use for stereotactic radiosurgery (SRS) of the brain. The advantage was that the low-dose region was spread out over a larger amount of healthy brain, reducing treatment toxicity.

Few imaging market segments have seen as much activity in the past six to nine months as digital radiography (DR) has. Comprising everything from retrofit kits to full suites — with a score of wireless options — the marketplace is filled with vendors improving old systems, introducing new ones and getting their products into more healthcare providers’ hands.

While computed tomography (CT) has revolutionized medical imaging, it has also required much higher doses of ionizing radiation than was previously used in traditional X-ray imaging. In recent years, vendors have turned their attention to developing technology to drastically reduce dose.

With the advent of handheld ultrasound systems, the idea of a doctor in the emergency department (ED) with an ultrasound clipped to his keyboard is not too far-fetched. We are not there yet, but competition is growing in the market. While there are signs the market has begun to mature, there also are signs it could expand into new territory.

AxoTrack sterile procedure kit

Soma Access Systems LLC received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its AxoTrack sterile procedure kit. Portable ultrasound maker Terason also recently received 510(k) clearance for the first ultrasound probe to be equipped with Soma’s patented AxoTrack virtual needle technology.


It seems a picture is worth more than a thousand words for people who see evidence of coronary artery disease, the most common type of heart disease in men and women. Simply seeing a build-up of calcium in the walls of arteries appears to prompt patients to better adhere to both statin therapy and recommendations for weight loss, according to research presented at the American College of Cardiology’s 61st Annual Scientific Session in Chicago.

Interventional radiology treatments re-establish blood flow in people with chronic deep vein thrombosis (DVT), reducing disabling symptoms and improving the quality of life for those afflicted with post-thrombotic syndrome—an under-recognized but frequent long-term complication of DVT. Researchers presented these findings during March's DVT Awareness Month at the Society of Interventional Radiology's (SIR) 37th Annual Scientific Meeting in San Francisco.
