Autodrive is an open source, .NET framework component for automating medical physics beam measurements. It includes APIs for interacting with standard equipment including electrometers, scanning systems and even a linac (currently limited to Varian C Series linacs).
- PTW Unidose
- Standard Imaging Max 4000 and Max 4000 Plus
- PTW TBA Electrometer (with MP3 scanning system)
- PTW Tandem TBA Controller
- Standard Imaging DoseView1D
- Varian Medical Systems C-Series Linacs
Linac control is perfomed using a keyboard emulator through the service mode console. The API has a map of the Varian Service Mode console and executes as if a user was entering keys. It can be thought of as a very sophisticated macro with fine grained control. The API has the method that looks like:
MachineState ms = MachineState.InitNew();
ms.X1 = 10;
ms.MU = 200;
ms.GantryAngle = 270;
Linac l = new CSeriesLinac();
l.Initalize("COM3"); //Uses RS232 to keyboard P/S2 interface
l.SetMachineState(ms); // Modes up whatever you put in
l.BeamOn();Warning: Controlling a radiation device and large mechanical components via a robotic software system should be done with extreme care. Please use with caution and at your own risk.
