QRM -Spectral CT Phantom for Dual-Energy and Photon-Counting CT Modalities
The Spectral CT Phantom by QRM is a specialized tool designed for testing various CT modalities including dual-energy, multi-energy, and photon-counting setups. This phantom is housed in a 100 mm cylinder with eight 20 mm diameter holes to accommodate different solid rods and fillable tubes. It supports the evaluation with water or contrast media. The set of solid rods available includes materials with varying concentrations of Iodine and Ca-Hydroxyapatite (CaHA), as well as equivalents for various tissues such as water, adipose, muscle, bone, and lung, following specifications in ICRU Report 44 and 46. Key technical parameters include mass density, electron density, and effective atomic number for all materials. The device maintains accuracy within ±5 HU of specified values, though nominal values may vary based on manufacturing methods and the imaging device used. This makes it an ideal choice for precise calibration and testing of CT imaging systems.
- D100 compatible
- Test the accuracy and consistency of spectral CT
- Test the Scanner performance
- Perform a material characterization and quantification of tissue-equivalent materials
- Decompose Iodine and CaHA levels
- Test the post-processing techniques of spectral CT
The Spectral CT Phantom can be used to test different types of CT modalities with dual-energy, multi-energy or photon-counting setups.
The 100 mm cylinder contains 8 holes (QRM-10147) with 20 mm diameter to house different solid rods and fillable tubes that can be used with water or contrast media.
The set of solid rods includes different concentrations of Iodine and Ca-Hydroxyapatite (CaHA) as well as water- and soft tissue-equivalents (adipose, muscle, bone, and lung according to ICRU Report 44 and 46). Mass density, electron density and effective atomic number are provided for all materials.
