CTphantomen

CTphantomen are specialized objects used in medical imaging, specifically in computed tomography (CT), to test and calibrate CT scanners. These phantoms are designed to mimic the physical and material properties of human tissues. They are typically made of materials with known attenuation coefficients, such as plastics, water, or specialized tissue-equivalent materials. By scanning these phantoms, medical physicists and radiologists can assess various aspects of the CT scanner's performance. This includes evaluating image quality, ensuring accurate Hounsfield unit (HU) values, checking spatial resolution, and verifying slice thickness. Regular use of CTphantomen is crucial for maintaining diagnostic accuracy and ensuring patient safety by confirming that the scanner is functioning correctly and producing reliable images. Different types of phantoms exist, each designed to test specific parameters. For example, some phantoms are simple uniform cylinders, while others contain complex arrangements of holes, wires, or different materials to simulate anatomical structures and pathological conditions.
