Head and neck phantom with realistic anatomy. This highly realistic head and neck phantom was designed to simulate clinical imaging and dose exposure in computed tomography including dual energy CT, X-ray imaging and radiation therapy. The model provides a realistic simulation of all tissues and realistic attenuation values. This phantom provides a detailed simulation of patient exposure and provides new opportunities for testing and optimizing image quality and dose, dose verification at low and high energy exposure and for training of medical and technical staff. The phantom is manufactured based on a real CT data set and includes anatomic details for all tissues. The model is a handmade unique piece, which can differ slightly in size and design. The phantom can be provided as one-piece anthropomorphic phantom or in a sectional design and it can include openings for dosimeters. Pathologic features (e.g., masses, vascular pathologies) can be included upon request into the phantom.
