Table 2.
Comparison of time spent on PSQA procedures per patient plan for various treatment sites with manual and automated workflow components. The number of fields for each site determined from PSQA log of 890 patient fields previously receiving QA. The preparation and analysis time reduction per plan achieved with automation is shown across all disease sites. Measurement time using manual methods was not recorded for this study, so only current measurement times using the DigiPhant assembly are reported here. Consequently, overall PSQA time savings are reported assuming no improvement was made to measurement time
