The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue. These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic and ultrasonic imaging technologies. "The ability to provide phantoms that are capable of mimicking desired properties of soft tissue is critical to advance the development of new, more-accurate imaging technologies," said Stanislav Emelianov of the University of Texas at Austin and co-author of a paper appearing in the Optical Society's (OSA) open-access journal Biomedical Optics Express that describes an improved method for fabricating tissue phantoms.
