Data Overview

Use the Data area to manage measured, TPS, and reference beam data for a selected linear accelerator.

First-Time Path

If you are new to Quadrant, start here:

1. Read Create a Data Set so you know how data is organized.
2. Read Select a Data Set so you understand how Quadrant chooses the institution, linear accelerator, and data set used on Data pages.
3. Read Import Data before adding files.
4. Use View a Data Set and Scan Data Table to review what was imported.
5. Use Export Data only after the selected data set has been reviewed.

What a Data Set Is

A data set is a named collection of scan data for a linear accelerator. Each data set also has two labels that help identify how it should be used:

• Source describes where the data came from: Measured, TPS, or Other.
• Type describes how the data is used: Commissioning, Annual, Monthly, or Misc.

Data sets can also carry a Baseline label. See Baseline for what the badge means and how it relates to Reference Data.

Data Pages

Use the Data menu in the application sidebar:

Page	Use It When	What You Can Do
Scans	You want to inspect what is already in a data set.	Review scan and wedge factor tables, select scans for plots or details, check unavailable scans, export the table view, and delete selected items if you have write access.
Import	You have new measurements, TPS dose data, pasted scatter values, or detector output to add.	Choose the destination data set, pick the import method, review detected scan information, handle duplicate warnings, and add the data to the selected data set.
Export	You need files for another system or review workflow.	Choose an output format, set resampling or calibration options when needed, and download the generated export package.
Databook	You want a structured beam-data summary rather than the row-by-row scan table.	Review TG-51, PDD, scatter, OAR, cone factor, VSD, wedge factor, and Scp/Sc/Sp summaries; choose Databook settings; export Databook output.

Each page uses the same selection pattern. Choose an institution, then a linear accelerator, then a data set. The current selection appears in the page header.

Caution

If a page opens with a previous selection, confirm it before taking action.

For a walkthrough of the data set selector, see Select a Data Set.

Recommended Workflow

1. Open Data > Scans.
2. Select the institution and linear accelerator.
3. Create or select the data set you want to work with.
4. Open Data > Import and add the measurements.
5. Return to Data > Scans to review the imported data.
6. Use Data > Export when you need files for another system.

Caution

If the selected data set is wrong, stop and choose the correct one before importing or exporting. Imports and exports are tied to the selected data set.

Three Different Exports

Quadrant has more than one export path:

Export	Where It Is	Use It For
Table export	Data > Scans, in the scan table toolbar	Copying or downloading the current table view.
Data set export	Data > Export	Creating files for another system or review workflow.
Databook export	Data > Databook, in the Databook toolbar	Exporting the Databook-format summary from the Databook view.
