    Intraoperative assessment of canine soft tissue sarcoma by deep learning enhanced optical coherence tomography

    Soft tissue sarcoma (STS) is a locally aggressive and infiltrative tumor in dogs. Surgical resection is the treatment of choice for local tumor control. Currently, post-operative pathology is performed for surgical margin assessment. Spectral-domain optical coherence tomography (OCT) has recently been evaluated for its value for surgical margin assessment in some tumor types in dogs. The purpose of this study was to develop an automatic diagnosis system that can assist clinicians in real-time for OCT image interpretation of tissues at surgical margins. We utilized a ResNet-50 network to classify healthy and cancerous tissues. A patch-based approach was adopted to achieve ...
