DATA ACQUISITION AND STORAGE Sample Clauses

DATA ACQUISITION AND STORAGE. All portable radiographs were single view radiographs of the chest or abdomen performed in standard fashion with the technologist confirming patient identity verbally or by wristband information. Immediately prior to obtaining the radiograph, a single photograph of the patient’s face and chest was obtained by placing a camera immediately adjacent to the properly positioned radiographic equipment. All photographs were obtained by a single individual with a 5-megapixel camera on an Apple iPhone 4 (Apple Inc., Cupertino, CA), with the use of a flash. Photographs were initially stored in Joint Picture Experts Group (JPEG) format. Prior to patient photograph acquisition, a photograph of the paper requisition form was also obtained to ensure that no errors were made in the matching of the radiographic study with the patient photograph. On occasion, studies were added to the worklist and the technologist was paged with the request when he/she was already on the floor; thus radiographs were obtained without the aid of the requisition form. For any study for which an acquisition number was unavailable at the time of the examination, acquisition numbers were acquired from the Picture Archiving and Communications Systems (PACS) using other patient identifiers, including name, date of birth, medical record number, and date and time the study was performed. All photographs and patient information were stored on a research computer with password encryption to ensure protection of patient information.
