Product model:

Brief description:The cone beam (CBCT) electron density model is an extended version of the CIRS 062M electron density model and is specially designed for cone beam CT imaging systems. Preliminary data suggest there may be differences between HU readings from diagnostic CT and cone beam CT. The geometry of cone beam CT requires additional materials and suggests that off-center axis measurements should be made.

cone beam (CBCT) electron density model is an extended version of the CIRS 062M electron density model, which is specially designed for cone beam CT imaging systems. Preliminary data suggest there may be differences between HU readings from diagnostic CT and cone beam CT. The geometry of cone beam CT requires additional materials and suggests that off-center axis measurements should be made.

The phantom is related toDesigned in collaboration with Dr. Peter H. Cossmann to provide a reliable tool for correcting electron density for CT numbers in volume imaging. Reliable CT calibration curves facilitate treatment plan adjustments directly based on cone beam CT data. Additionally, the phantom can accommodate any ion chamber for dose measurement and verification of heterogeneity correction based on corrected CT calibration curves.

ourThe dimensions of the Type 062MA CBCT electron density model cover imager geometries up to 40 cm x 40 cm. It is made from PlasticWater® and contains the same set of tissue-equivalent electron density inserts as the standard model 062. Other interchangeable plates allow electron density sections to be repositioned in 2.5 cm increments.

Note:The 062MA is just one of three configurations of the complete cone beam CT electron density & image quality phantom system.
