August 2, 2011 – The American Society of Echocardiography (ASE) has developed iASE, a tool that provides clear, concise summaries of the ASE’s most popular guidelines as applications for mobile devices. This highly portable tool allows physicians to access guidelines and calculators for echocardiography in one place, combining many steps traditionally taken by practitioners into one easy step, according to Chi-Ming Chow, M.D., associate professor of medicine at the University of Toronto and staff cardiologist at St. Michael’s Hospital, Toronto, Ontario. Chow, part of the team that created the application for ASE’s Information Technology (IT) Committee, noted that while ASE’s posters and pocket guides to the guidelines for cardiovascular ultrasound are wonderful in traditional settings, the mobile application can be used by practitioners anywhere: at the patient’s bedside, while teaching residents how to take measurements or when sharing calculations with sonographers, making it an ideal teaching and reference tool.

July 27, 2011 – As the number of interventional procedures to diagnose and treat patients increases worldwide, and the procedures grow in complexity and length, exposure to radiation is a growing concern for both clinicians and patients. Interventional fluoroscopy is the third largest source of radiation from medical procedures, accounting for about 7 percent of the total radiation exposure of Americans in a year, according to a study by the National Council on Radiation Protection. GE’s Innova imaging systems help clinicians reduce radiation exposure without compromising the image quality they need to make confident decisions during interventional procedures.
