Description
Adult Knee for X-Ray CT, US, MRI
Product Description
The Adult Knee phantom is designed based on the anatomy of an average adult human male knee. It is a multi-modality tool compatible with X-Ray/CT, Ultrasound, and MRI imaging. The phantom utilizes patented synthetic bone material and realistic urethane-based tissue-mimicking materials for soft tissues, tendons, ligaments, and cartilage. It serves as an essential tool for medical imaging research, radiology training, and orthopedic studies.
The internal structure replicates the complex biomechanical properties of a real human knee, allowing for high-fidelity testing and calibration. For MRI, the phantom provides realistic T2 relaxation time values (50 ms). This phantom can be customized with specific pathologies or alternative internal features upon request.
Note: By default, the phantom comes in a translucent amber appearance. A skin finish can be included upon request. The model is available in two versions: "Ligaments/Tendons" or "Bones Only".
