Abstract

The initial steps in fabricating a multimodality imaging phantom for combined diffuse optical tomography and ultrasound tomography (DOT-UST) are completed. Phantoms are intended to mimic the optical and acoustic properties of breast tissue for near infrared light and ultrasound in the vicinity of 2 MHz. So far, a prototype ultrasound tomography system has been designed and the acoustic attenuation coefficient of glass beads has been characterized. Furthermore, 8 cm diameter homogeneous cylindrical phantoms have been successfully constructed and it has been shown that an inclusion with object to background contrast of three can be comfortably detected with the prototype system.
