CK COLLI

Software Module (Quality control of Iris collimator and cones)

Quote

Connected to the QUALIMAGIQ platform, it takes only 2 mouse clicks for the CK-COLLI module to analyse the many DICOM images acquired with the high-energy portable imager from QUALIFORMED, CK-IMAGER, in the context of quality control of an « iris » type collimator and « cone » type collimators.

 

AUTOMATIC ANALYSIS OF THE CONTROL OF THE PERFORMANCES OF THE IRIS COLLIMATOR AND CONES USED TO DELINEATE THE RADIATION BEAMS ON A CYBERKNIFE DEVICE  

 

For each image, these automated 2D* and 1D* analyses are carried out on:

  • The size of the radiation field, its penumbrae, its circularity, its shift relative to the centre of the field;
  • The size of the homogeneous zone, its homogeneity, its symmetry and its maximum deviation;
  • The Collimator « Output Factor » associated with the analysed field.

​

For all of the images associated with each type of « iris » or « cone » collimation, QUALIMAGIQ also automates the analysis of the constancy of the Output Factor).

 

(*): The 2D analysis covers the entire surface of the image while 1D analysis consists of analysing a profile obtained by averaging the signal measured on 4 different profiles oriented respectively at 0°, 15°, 90 ° and 105°. The 1D analysis is less complete than the 2D analysis but it is equivalent to that recommended by ACCURAY.

 

Necessary measuring equipment: CK-IMAGER from QUALIFORMED, its accessories and test-objects CK-COVER-TRUE, CK-COVER-DUMMY and CK-SLAB-FIDU..
