The Focused Assessment of Sonography for Trauma (FAST) is a rapid point-of-care ultrasound exam performed on blunt and penetrating trauma patients who are too critically injured to be transported to a CT scanner. In performing this exam, time to acquisition of adequate images is crucial to clinical decision-making as patients undergoing this exam have a high probability of deteriorating if not intervened on appropriately.~Low-frequency ultrasound is used to image the abdominal cavity and pericardium in these patients, using either a curvilinear transducer or a phased-array transducer. Both of these transducers are capable of acquiring the images necessary to interpret a FAST exam, but it has not been well studied whether using one transducer instead of the other improves time to image acquisition or image quality.~In this study, physician ultrasound operators are asked to perform FAST exams on healthy non-injured volunteers for the purpose of determining if there is a difference in the time to acquisition or quality of images between phased-array and curvilinear transducers.
