Small animals such as rodents are indispensable models for preclinical and basic science research. Seeing inside their entire bodies with high spatial and time resolution could provide insights into biological processes, advancing studies of human disease and drug development.In a recent study, researchers describe a new deep tissue imaging technique called Single-impulse photoacoustic computed tomography (SIP-PACT) that can peer inside small animals with unprecedented detail.Read more about the improved imaging technique at Bioengineering Today: New Imaging Technique Yields Detailed, Whole-Body Videos of a Rat's Insides.
