Software development for imaging workstations needs improvement. Analyzing computed tomography (CT) interpretation workflows reveals bottlenecks, highlighting the need for better workstation design to enhance efficiency and reduce interruptions.

Area of Science:

  • Medical Imaging
  • Radiology Workflow Analysis
  • Human-Computer Interaction

Background:

  • Imaging workstation software development lags behind hardware advancements.
  • Understanding cognitive and physical processes in cross-sectional imaging interpretation is crucial for optimizing workflows.

Purpose of the Study:

  • To analyze the workflow of body computed tomography (CT) interpretation.
  • To identify bottlenecks in the interpretation process.
  • To guide the development of improved imaging workstations.

Main Methods:

  • Direct observation of performance and interpretation of body CT scans.
  • Workflow analysis using bottleneck identification.
  • Recording of events during the interpretation process.

Main Results:

  • Comparison with prior scans occurred in 44% of cases.
  • Extensive use of non-soft tissue windows (87%) and review of previous levels (85%) were noted.
  • Bottlenecks identified: film retrieval for film-based reading and the CT examination itself for PACS reading.

Conclusions:

  • CT interpretation workstations should enhance navigation, comparison with prior studies, and lesion measurement.
  • Future workstation design should optimize inter-session time, minimize interruptions, and automate physician-intensive functions.
