Anatomica: Engineering an Anatomical Model

Abstract

Precision Phantoms addresses the gap in medical device calibration and validation for processing as well as in preclinical trials by creating biomimetic phantoms using composite solid gels as the foundational material that simulate the electrical, thermal and anatomical properties of human tissues. These phantoms aid accurate testing and calibration of energy-based medical devices for diagnostic and therapeutic purposes.

The market for anatomical phantoms is vast with gaps in clinical, educational and most importantly research applications within the physical medicine and device manufacturing industry. Device manufacturers are constantly seeking realistic models to alleviate the reliance on living models and for better calibration of their new devices. Existing phantoms in the market are limited due to being unable to offer both anatomical structure as well as the desired electrical properties.

The core concept consists of a layered model that mimics different tissues such as skin, muscle and bone. This concept utilizes agar agar solid gels in which the dielectric properties can be tuned by incorporating additives such as sodium chloride, and glycine. The solid gel design will also allow for the hosting of probes and sensors for mapping of the electromagnetic fields at all points inside and outside the phantom. The design is reliable and easily replicable making use of inexpensive and readily available materials and standard lab equipment. The fabrication process is straightforward and can be integrated into existing lab workflows. The manufacturing process is designed to keep overall expenses minimal.
