The ASRT recently released the following important position statements:
Digital Imaging Cropping or Masking in Radiography
It is the position of the American Society of Radiologic Technologists that a digital image should not be cropped or masked such that it eliminates areas of exposure from the image that are presented for interpretation. Pre-exposure collimation of the x-ray beam is necessary to comply with the principle of as low as reasonably achievable (ALARA). To determine that exposed anatomy on an image is not significant or of diagnostic value is a medical decision and is therefore outside of the scope of practice for a radiologic technologist.
Adopted, Main Motion, C-14.10, 2014
Digital Image Post-Processing in Radiography
It is the position of the American Society of Radiologic Technologists that an image obtained for a prescribed projection in a digital imaging system or series be assigned only to that specific projection and not be altered by post-processing in order to be represented as another projection.
Adopted, Main Motion, C-14.07, 2014
Monitoring Patient Exposure During Utilization of Digital Radiography Systems
It is the position of the American Society of Radiologic Technologists that health care facilities using digital radiography systems monitor patient exposure. Exposure indicator data should be included in the Digital Imaging Communication in Medicine (DICOM) header for images sent to picture archiving and communication systems (PACS) or in the patient demographics field for all imaging studies and should be part of the permanent patient record. The exposure indicator should not be altered to modify image appearance and should accurately record the exposure or exposure factors used in producing the image. Health care facilities should collect patient exposure range distributions and reject analyses as part of the quality assurance program. This exposure data should be reviewed routinely by the health care facility.
Adopted, Motion 14.15, 2014
