QRM products

The QRM Electron Density Phantom, model D100 (QRM-90110), is designed for the precise calibration of Hounsfield Units (HU) versus electron density in CT and CBCT radiotherapy treatment plans. This device includes five interchangeable tissue-equivalent material inserts that mimic real human tissues in terms of physical and electron density, consistent with ICRU Report 44 and 46. These properties are vital for accurate radiation oncology treatment planning. The phantom ensures an accuracy of ± 5 HU from the specified values, providing a reliable standard for the calibration processes necessary in medical imaging and therapy planning systems.
