These reports enable you to analyze fluoroscopy dose data using a variety of filters to obtain an overview of your performance and to delve into the details. You can identify outlier exams, highlight other patterns for further investigation, and find missing data and gaps in data transmissions.
Get started by selecting a Corporate Account, a corresponding Facility, or Facilities, and a timeframe of interest.
Exam Search: This tool enables you to query procedures using a variety of criteria. The sample screenshot below shows results associated with all adult procedures across all stations for a 30-day period.
The individual exam data appear on the left side of the table, with Total Fluoro Time (min.), Cumulative Air Kerma (mGy) and Kerma-Area Product (Gy*cm^2) provided on the table's right side. Also included in the table's right side are two derived indices: Average Reference Air Kerma Rate (mGy/min) and Average Field Size (cm^2). Reference Air Kerma Rate is an estimate of the exam’s average air kerma rate value, calculated by dividing the Cumulative Air Kerma by the Total Fluoro Time. Average Field Size is similarly calculated by dividing the Kerma-Area Product by the Cumulative Air Kerma. The bar chart to the right of the table summarizes the distribution of exams by Study Type using either the mapped ACR Common procedure names or a facility’s internal clinical procedure names (Study Description or Procedure Description) populated in the DICOM header. Selecting a bar in the chart will filter the report by the procedure.
Scatterplot: This feature helps you identify unusual patterns or outliers for DIR Fluoro dose indices. Use the report filters and parameters: Fluoroscopy Measure, Age Group, Body Area, and Study Type, to refine the data in the scatterplot. You also can hone in on facility performance by specific station and equipment manufacturer and model. The following screenshot illustrates several components of the scatterplot.
The report plots the value of each Cumulate Air Kerma (mGY) measure for 508 procedures by date for a 30-day period. The Station Statistics table summarizes the number of observations and minimum, maximum, and median measure values with red highlighted text indicating the largest values within each column. Hovering over a measure dot in the scatterplot provides exam details, and clicking a measure dot will add a link to the Index Comparisons report to view boxplots of all indices for all exams for that procedure.
Boxplot by Scanner: Filters allow you to assess dose index data between scanners for one or more facilities in a box-and-whisker format. In the example below, hovering the cursor over the shaded “box” area displays the Kerma-Area Product quartile data for abdominal procedures over a 30-day period with the black horizontal “whisker” lines denoting the cutoff for statistical outliers. Hovering over a single measure dot shows procedure details.
Changing the Station Detail parameter from Device to Model may provide a more useful comparison by aggregating data to the model level, as different stations may require different dose levels to obtain the same quality diagnostic image.
Boxplot by Procedure: These filters allow you to analyze dose indices by procedure for one or more facilities in a box-and-whisker format. In the example below, hovering the cursor over the shaded “box” area for Biliary displays the Kerma-Area Pro quartile data for abdominal procedures over a 30-day period with the black horizontal “whisker” lines denoting the cutoff for statistical outliers. Hovering over a single measure dot shows procedure details.
Index Comparisons: The screenshot below illustrates how charts of the dose indices can help to identify outliers across dose indices. Select one or two procedures at a time for the best report view. Clicking a measure dot in a chart highlights the same exam across all five boxplots.
