Models

You can select a model from the left panel to display its characteristics.

The first models considered in the OpenDose project are the adult reference computational phantoms defined by the ICRP in the publication 110 [1]. These two voxel-based models represent the average anatomy of male and female humans. They have been developed by the ICRP using medical image data of real people and adjusted to the adult reference male and female data [2]. These reference phantoms are used by the ICRP to establish radiation protection guidance.

These models comprise 141 segmented regions and 53 different media. The adult female is described by 299 x 137 x 348 voxels of size 1.775 x 1.775 x 4.84 mm, corresponding to a height of 1.63 m and a mass of 60 kg. The adult male is described by 254 x 127 x 222 voxels of size 2.137 x 2.137 x 8.0 mm, corresponding to a height of 1.76 m and a mass of 73 kg.

In addition to the original 141 individual regions of the models, 31 compound regions have been added to regroup parts of an organ (ex. kidneys being composed out of regions 89 to 94). These additional regions are the same as the target compound regions and “Total body except organ contents” defined in Table D.1 and C.1 of ICRP publication 110, respectively [1].

This section allows to display information on models considered for OpenDose. A table displays general information alongside with an image of the selected model in a density equivalent representation. A table at the bottom of the page indicates the volume and mass of all regions of the selected model:
