2. The Problem

Isocenter coordinates from the TumorLoc application & Philips Big Bore CT scanner are not automatically transferred to our Gammex lasers and need to be manually inserted.

3. Key Use Case

How it works now:

- The User marks an isocenter in the TumorLoc software application

- The User reads the isocenter co-ordinates on the screen

- The User manually enters the isocenter co-ordinates into the laser control computer

- The User then manually moves the CT couch to the desired couch position.

How it should be:

- The User marks an isocenter in the TumorLoc application

- The application automatically transfers the co-ordinates to the laser control computer

- The application automatically transfers the couch position to the couch control system

- The User moves the couch by pressing the couch release button.

4. Standards & Systems

DICOM RT objects.
