In 2011, IT’IS published the first version of its tissue properties database to provide the computational life sciences community with values for electromagnetic, thermal, fluid, acoustic, and magnetic resonance properties of biological tissues in a free, easily accessible, and dynamically evolving manner. The database includes a wide collection of physical material properties that is updated and extended for a large range of biological tissues on a regular basis. Today, we are proud to announce the release of V4.0 of the database, which now includes the elemental composition. The elemental composition of a tissue represents the percentage of a specific element found in the tissue and is commonly used to approximate the tissue attenuation coefficient of photons in the higher electromagnetic spectrum, such as x-ray or gamma radiation. The release also includes thermal and dielectric properties for several new tissues in the eye: choroid, retina, iris, aqueous humor, and ciliary body.
The new database including the elemental composition can be found here.
