Imaging phantom

For instance, phantoms made for 2D radiography may hold various quantities of x-ray contrast agents with similar x-ray absorbing properties (such as the attenuation coefficient) to normal tissue to tune the contrast of the imaging device or modulate the patient's exposure to radiation.

In such a case, the radiography phantom would not necessarily need to have similar textures and mechanical properties since these are not relevant in x-ray imaging modalities.

[2] The term "phantom" describes an object that is designed to resemble human tissue and can be evaluated, analyzed or manipulated to study the performance of a medical device.

Phantoms are created using a digital file that is rendered through magnetic resonance imaging (MRI) or computer-aided design (CAD).

The 3D printer will create the product in successive layers using polymeric materials.
