Patient Positioning Devices
The Patient Positioning Devices in the treatment room allow you to position the
patient for treatment. You may control them using the wireless hand-pendant or the
remote positioning controls.
Note: For details on how to move the PPDs with Manual and Auto motions using
the wireless hand-pendant, refer to Chapter 9. For details on how to move the PPDs
with Manual and Auto motions using the remote positioning controls, refer to
Chapter 11.
The Patient Positioning Devices in the GTR are:
 Patient Positioning System (PPS): the PPS is the mechanical arm that serves to
position the patient laying on the couch.
 Dedicated Nozzle Snout Holder (DNSH): the DNSH is the device that holds the
accessory drawer and is capable of bringing it closer or further from the patient
skin for treatment.
 Accessory Drawer: the device capable of putting the accessory fully in or out of
the beam path depending on whether or not the accessory is used in the
prescription.
 Gantry: the device capable of rotating the nozzle to deliver the proton beam from
different angles.
Patient Positioning System (PPS)
Note: For information on how to manually operate the PPS (in case of emergency),
refer to Chapter 16, “Operating the Patient Positioning System Manually (Emergency
Release Mode)”.
The Patient Positioning System (PPS) has six axes of movement that can be
controlled using the hand-pendant or the remote positioning controls.
Note: PPS positions are always displayed according to the TTCS in the FRS.
Note: Auto PPS motions are managed in such a way that movement along all
involved axes is synchronized. As such, the PPS trajectory is not defined in TTCS
terms.
Note: PPS Manual movements follow the TTCS for translations along the X, Y and
Z axes as well as for top rotation.
