"If it's not easy, if it's not accurate, no one is going to use it," says Kuhls-Gilcrist, who is the AAPM Junior Investigator Winner.
The procedure takes about ten minutes. A radiologic technologist pushes the button on the X-ray equipment to acquire a few "blank" images. Then a computer program automatically analyzes the noise in these images and calculates a range of quantitative measurements such as the detective quantum efficiency, which indicates how effectively a scanner uses each dose of radiation. Other measurements of instrument noise check for problems that could affect the image quality of low-dose procedures such as fluoroscopy.
This method of quality assurance procedure has proven to be just as accurate as tests used by scientists in the laboratory, in which expensive, precisely-fabricated objects with near-perfect straight edges are imaged.
The presentation, "A New Simple, Accurate, and Quantitative Approach for Routine Quality Assurance in Digital Radiography" by A Kuhls-Gilcrist, D Bednarek, and S Rudin will be at 4:00 p.m. on Monday, July 19, 2010 in Room 204B of the Pennsylvania Convention Center.
8) Time Out Procedures Reduce Error Rates
PHILADELPHIA, PA (July 22, 2010) -- Imagine the following announcement: "Our patient is Ken Chu. We are amputating his left arm. Does everybody agree?"
Welcome to a hypothetical "Time Out" (TO) statement and question set, a standard operating room procedure among surgeons to reduce errors by assuring the patient receives the correct treatment.
And now Ken Chu, PhDwho happily has both arms and is Chief Medical Physicist at Marquette General Hospital in Michiganhas conducted a study whose data argue fo
