A Jaszczak phantom (Polish pronunciation: [ˈjaʂ.t͡ʂak] ⓘ) aka Data Spectrum ECT phantom [1] is an imaging phantom used for validating scanner geometry, 3D contrast, uniformity, resolution, attenuation and scatter correction or alignment tasks in nuclear medicine.
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).

An example of a video game that made extensive use of open playtesting is Minecraft, which was made available for purchase in its pre-alpha stages. This both helped to financially support the game and provide feedback and bug testing during its early stages.
The phantom has a 4D beating heart model which was derived from 4D tagged (MRI) data. The remaining organs in the torso of the phantom were designed based on the Visible Human Project CT data set and were composed of 3D NURBS surfaces. Respiratory motion was also incorporated into this phantom.
A phantom head was described by researchers in 2015. This head was developed at the U.S. Army Research Laboratory . [ 1 ] Reported intent for the engineering of this phantom head was to “accurately recreate real and imaginary scalp impedance, contain internal emitters to create dipoles, and be easily replicable across various labs and ...
The Advisory Committee on X-Ray and Radium Protection was established in 1929. [1] Initially, the organization was an informal collective of scientists seeking to proffer accurate information and appropriate recommendations for radiation protection.
