Pro-RT AlignCube


A versatile and easy-to-use tool for regular quality control of the geometric accuracy of the patient positioning systems.  It enables the assessment of the alignment between the isocentre of the imaging system (CBCT, 2D kV, 2D MV) and the LINAC isocentre. 

Pro-RT Align-Cube phantom contains radiographic markers in an arrangement that allows evaluation of the translation and rotation of the phantom relative to the reference position. The marker material has been selected to ensure good visibility while avoiding artefacts which could compromise image registration. The position of the markers is clearly labelled on the phantom surface. 

Due to the additional markings of the offset positionon the phantom surface, it is possible to quickly evaluate the accuracy of the automatic couch shift adjustment.

It can be used to test:

  • imaging systems (CBCT, 2D kV, 2D MV) and LINAC isocentre alignment
  • automatic couch shift adjustment
  • laser to isocentre coincidence
  • SGRT systems  
  • optical distance indicator accuracy
