|Part XI - Patient Positioning and Alignment Calculating Corrections Using adaPT insight |
After completing the registration, images are “locked” to enable you to cross check
the result but not modify it.
Correction Feedback
After Image Registration and calculation of the correction, it is necessary to apply
these corrections to the Patient Positioning Devices.
How to Interpret adaPT insight Corrections
The correction is expressed as a transformation from the IEC-Fix to the IEC-TTCS
coordinate system according to the IEC 61217 standard, which defines the order of
the translation and rotation calculations. It represents the shift to apply to the PPS in
order to properly align the patient to the prescribed position.
Six different corrections are supplied:
 The X, Y, and Z corrections are expressed in cm.
 The Rot, Pitch, and Roll corrections are expressed in degrees.
If a value N/A (not applicable) appears, this means that the value cannot be computed
due to insufficient input data, e.g., if only one DR has been taken.
