Abstract
Several oncological surgery scenarios, such as suspected lesion finding, lesion differentiation or tumour margin clarification will benefit from real-time and quantitative imaging. Optical Coherence Tomography (OCT) systems interfaced with needle based or endoscopic catheters are developed to address these scenarios. Additional light-tissue based quantification of the acquired data also allows for tissue stratification, such as the assessment of tumour grade (aggressiveness) and stage (invasiveness). We will present the latest results of quantitative OCT in urology during minimal invasive surgery of urothelial cancer and percutaneous (through the skin using small needles) diagnosis of kidney cancer.
