Phantoms are objects designed to mimic the properties of human tissue and are used to study and develop new medical imaging and treatment options. The development of phantoms that accurately and reliably mimic the properties of human tissue is extremely important in the field of MRgFUS. Phantoms are used in quality assurance and validation of new imaging and treatment techniques. A variety of commercial phantoms for use with ultrasound or MR are available, however we believe that fabricating phantoms with custom shapes and tissue properties is essential to our research process. We have developed a methodology for fabricating gelatin phantoms that successfully mimic many of the acoustic, thermal and mechanical properties of human tissue. These phantoms are relatively simple to make and easily modifiable which allows them to be used for a variety of experiments.
