Repeated CT for an anthropomorphic phantom with different nasal cavity fillings

Anthropomorphic head-and-neck phantom, developed at Paul Scherrer Institute in collaboration with CIRS (Computerized Imaging Reference Systems, Inc., Norfolk, USA) and made from a material equivalent to human tissue. To simulate different anatomical changes, the nasal cavities can be filled with a material equivalent to mucus, and a layer of fat can be applied to the neck to simulate weight gain/loss. The phantom has been first introduced here: DOI 10.1088/1361-6560/ac2b84 In this repository, we include 26 different CTs presenting anatomical and/or positioning variations with respect to the reference CT. A readme file provides more information regarding the different CT images included in this dataset.
