INTRODUCTION

This Amendment 2 extends the rotation of the patient support devices around the Z-axis in the

IEC fixed coordinate system to two additional rotations – rolling around the patient’s

longitudinal axis and pitching around the patient’s transversal axis.

The use of the two new additional degrees of freedom (pitch and roll) generalizes the

coordinate systems to include systematically 3 rotations and 3 translations, therefore

supporting 6 degrees of freedom in a systematic way. Modern patient support devices with 6

degrees of freedom can use a combined translation and rotation to get the same result as the

eccentric table top rotation. When changing table position data using the new IEC systems,

the definition of isocentric rotations is sufficient to transfer all treatment-related information.

The eccentric table top coordinate system is however maintained for backward compatibility.

NOTE It is quite common in proton therapy to use a treatment chair, where the patient can be rotated and tilted,

while the beam line has a fixed direction.
