Quantitative Ultrasound Characterization of Cancer Radiotherapy Effects In Vitro

PURPOSE: Currently, no routinely used imaging modality is available to assess tumor responses to cancer treatment within hours to days after radiotherapy. In this study, we demonstrate the preclinical application of quantitative ultrasound methods to characterize the cellular responses to cancer radiotherapy in vitro. METHODS AND MATERIALS: Three different cell lines were exposed to radiation doses of 2-8 Gy. Data were collected with an …
