Table/Laser Shifts

Shifts

Full Descriptions

Ex. "Move the table RIGHT 7.59cm (looking from foot of table.)

TrialList.Current.BeamList.Current.LaserDescr.X;
TrialList.Current.BeamList.Current.LaserDescr.Y;
TrialList.Current.BeamList.Current.LaserDescr.Z;

Shift Value only

Ex. "7.59"

//X, Y, Z coordinate shifts
TrialList.Current.BeamList.Current.IsoInLocalizerCoords.XCoord;
TrialList.Current.BeamList.Current.IsoInLocalizerCoords.YCoord;
TrialList.Current.BeamList.Current.IsoInLocalizerCoords.ZCoord;

Direction Value

Ex. "RIGHT"

//X, Y, Z coordinate shift directions
TrialList.Current.BeamList.Current.LaserLabel.X;
TrialList.Current.BeamList.Current.LaserLabel.Y;
TrialList.Current.BeamList.Current.LaserLabel.Z;

Laser Infomation

Ex. "Lap CT1"
—-Need to verify this is correct.

TrialList.Current.LaserLocalizer.ExportFormat;

Isocenter Shifts Reporting (Coordinate System POV)

Ex. "Table"

TrialList.Current.BeamList.Current.DisplayLaserMotion;

Examples

Determine shifts and directions for the current isocenter

PoiList.Current=TrialList.Current.IsocenterList.Current.Name;

//on the type of laser system. Weird.
