Optical coherence tomography as a simple and non invasive tool for the diagnosis of oral disease: a case report
2015
Introduction. Optical Coherence Tomography (OCT) is a new biomedical imaging modality that provides high reso- lution cross-sectional images of tissue. Conceptually, it has been compared with ultrasound scanning but it uses in- frared light and records reflections below the surface to produce a cross-sectional architectural image of the tissue. OCT has been applied in ophthalmology and recently in dermatology; several studies have shown the validity of the use of OCT in ex vivo oral lesions but, to date, it does not exist a bank of normative and pathological OCT data of the oral tissues to consent identification of cellular structures of normal and pathological processes. We report a case o…
Implementation to Back-Projection Techniques of Resistivity Data
2005
In order to obtain well contrasted images by back-projection of resistivity data some modifications to the back-projection algorithm as well as the use of filtering techniques for the sensitivity matrix were proposed (Kotre 1994; Cosentino et al. 1998). To further improve the back-projection algorithm a new implementation is here suggested. Besides a subsequent filtering algorithm of the sensitivity coefficient matrix is proposed. It is aimed to increase resistivity contrasts and to reduce smoothness in tomographic final representation. Finally the proposed technique is tested on synthetic data.
