The settings of all Manual motions are displayed according to IEC61217 (refer to
"Supported Coordinate Systems" on page 7-3).
Manual Motions in a GTR
This section features a list of the Manual motions available in the different types of
treatment rooms when using Manual mode.
Note: For further information on how to perform Manual motions using the wireless
hand-pendant, refer to Chapter 9. For further information on how to perform Manual
motions using the remote positioning controls, refer to Chapter 11.

a. The Horizontal Table Top Coordinate System (HTTCS) is equivalent to the
IEC 61217 patient support coordinate system and as its name indicates, it
always remains horizontal. In the Proton Therapy System, it is used instead
of the TTCS for the execution of Manual PPS motions. This enables lateral
(X) and longitudinal (Y) motions to be horizontal displacements of the table
top even if there is a pitch or roll of the table. If the TTCS was used instead,
as it is stationary with respect to the table, lateral (X) motions would be ex-
ecuted on the plane of the current roll angle and longitudinal (Y) motions on
the plane of the current pitch angle.
