    Exploring optical coherence tomography imaging depth to differentiate tissues at surgical margins

    Optical coherence tomography (OCT) is an imaging modality that provides real-time visualization of tissue microstructure. The goals of this study were to assess OCT image tissue depths (TD) with image processing, and other objective characteristics of tissue types at surgical margins in canine soft tissue sarcoma (STS). In this study, a single observer reviewed 248 images of four tissue types (sarcoma, skeletal muscle, adipose and fascia) collected from 24 dogs with STS. The observer evaluated for tissue characteristics and measured TDs utilizing ImageJ software. Images were evaluated in normal, Threshold and Binary conditions. Measurements were repeated one week later to ...
