Abstract

A phantom consisting of a 2.5 cm diameter aluminum rod, a balloon filled with castor oil and a balloon filled with a phenylated silicone fluid were imaged in water with ultrasound transaxial tomography of attenuation by reconstruction (UTTAR). This phantom was chosen to investigate the feasibility of detecting small changes in the ultrasound attenuation coefficient of soft tissues in planes containing bones. Opposed transmitting and receiving transducers were scanned on either side of the phantom just as an x-ray tube and detector are scanned in the EMI x-ray computerized axial tomography system for brain imaging.© (1976) COPYRIGHT SPIE--The International Society for Optical Engineering.
