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).
It is used for accreditation by clinical and academic facilities for the American College of Radiology. [2] [3] The phantom was developed by Ronald J. Jaszczak [4] of Duke University, [5] and was filed for a patent in 1982. [6] It is a cylinder containing fillable inserts that is often used with a radionuclide such as Technetium-99m [7] or ...
Some playtests also try to evaluate the game's appeal to players with different levels of experience by selecting players with varying exposure to the game's genre. 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 ...
ACR Education Center – located in Reston, VA, offers specialized mini-fellowships in more than a dozen clinical areas. [3]American Institute for Radiologic Pathology (AIRP) – The AIRP conducts five courses for radiology residents and fellows, and seven categorical courses for practicing radiologists and other physicians each year in Silver Spring, MD.
Game testing, also called quality assurance (QA) testing within the video game industry, is a software testing process for quality control of video games. [ 1 ] [ 2 ] [ 3 ] The primary function of game testing is the discovery and documentation of software defects .
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.

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 research groups.” [7] The scientists used an inverse 3D printed mold that was reproduced an anonymized MRI image.
