title: Acoustic properties of polyvinyl chloride gelatin for use in ultrasonography.
abstract: Visualization of superficial structures with conventional rapid scanners has been difficult. A solid flexible polyvinyl chloride (PVC) gelatin slab used as a stand-off material can provide a constant scan distance and thus overcome the problem of poor near field resolution. PVC gelatin expands the capability of the 3-4 MHz transducer to delineate superficial structures. We report on the acoustic properties of the PCV gelatin, including the values of velocity and attenuation as a function of both frequency and temperature, and the comparison of data with published values of velocity and attenuation for water, soft tissue, and a phantom material.
