title: Development of a combined audiovisual and extremity dose monitoring software tool for use in nuclear medicine.
abstract: OBJECTIVE
  Conventional extremity dose monitoring in nuclear medicine, using thermoluminescent dosimeters, provides a convenient method of determining integral doses from a series of procedures. Although semiconductor extremity probes are able to add time information and allow doses from individual procedures to be determined, it can be difficult to relate individual operations to the dose-time curve. Solutions to this problem have been identified and developed.
  
  
  METHODS
  A novel software tool (Extremity Dose Information Package, EDIP) has been developed that uniquely combines and synchronizes two audiovisual and extremity probe data-streams. The value of this extra information was assessed by acquiring audiovisual and extremity dose information in nuclear medicine and radiopharmacy settings.
  
  
  RESULTS
  The ability of the software tool to synchronize audiovisual and dose data-streams was verified. Preliminary studies of handling techniques in radiopharmacy and radioiodine administrations using this tool showed areas in which techniques could be adapted to reduce extremity doses, which would have been difficult or impossible to identify using the dose-time information alone.
  
  
  CONCLUSIONS
  This low-cost multimedia extremity dose monitoring package can be used, for example, to aid staff training and pinpoint issues with current operating procedures within a clinical nuclear medicine department. Its unique ability to combine and synchronize audiovisual and dosimetry data is also likely to be of benefit to other industries handling unsealed radioactive materials.
