Portable wireless DR beats CR for some clinical tasks
Wednesday, November 28 | 11:20 a.m.-11:30 a.m. | SSK03-06 | Room S404CDThe incorporation of wireless digital radiography (DR) detectors into portable x-ray systems has brought major workflow advantages to radiology departments compared to computed radiography (CR). But does wireless portable DR also have an image quality advantage?

Technique estimates pediatric dose for DR studies
Monday, November 26 | 12:15 p.m.-12:45 p.m. | LL-PDS-MO2A | Lakeside Learning CenterHeightened concern over radiation dose has led to the development of new methods for calculating and reporting dose delivered to patients during imaging exams. Most of the attention has focused on CT -- but what about digital radiography (DR)?
