Enhanced visualization processing (EVP) significantly speeds up digital radiography review by reducing radiologist image manipulation time. This digital imaging technique improves workflow efficiency in picture archiving and communication systems (PACS).

Area of Science:

  • Radiology
  • Medical Imaging
  • Health Informatics

Background:

  • Digital radiography offers image processing for enhanced visualization but can increase radiologist viewing time.
  • Enhanced visualization processing (EVP) was developed to improve image latitude without compromising contrast, aiming to reduce manual manipulation.
  • This study investigates the impact of EVP on radiologist workflow within a Picture Archiving and Communication System (PACS).

Purpose of the Study:

  • To evaluate the effect of Enhanced Visualization Processing (EVP) on radiologist workflow.
  • To determine if EVP reduces image manipulation and viewing time in digital radiography.

Main Methods:

  • Portable computed radiographic chest images were processed with and without EVP.
  • Four radiologists reviewed images on a PACS workstation during their routine schedule.

  • Viewing times and use of zoom/window/level manipulation were recorded via video analysis.

    • Main Results:

    • Viewing time was significantly shorter for EVP-processed images compared to non-EVP images across all readers.
    • The use of zoom and window/level manipulation was reduced with EVP.
    • Time spent on image manipulation tools was significantly less when using EVP.

    Conclusions:

    • EVP significantly improves radiologist workflow efficiency for chest images on PACS monitors.
    • EVP reduces the frequency and duration of image manipulation, such as zooming and window/level adjustments.
    • The findings suggest EVP is a valuable tool for optimizing digital radiography interpretation.
