In-vivo, Percutaneous, Needle Based, Optical Coherence Tomography of Renal Masses
Optical coherence tomography (OCT) is an imaging technique, based on the backscattering of near infrared light. Within OCT images the attenuation coefficient (µOCT) can be calculated, expressing the loss of signal per millimeter of tissue penetration. During carcinogenesis cellular changes take place that alter tissue scattering properties. We hypothesize that the µOCT is higher in malignant versus benign tumours, providing the means for tumour differentiation. The aim of this study is developing OCT into an instant and accurate technique for tumour differentiation.
