Advanced Image Processing in Support of THz Imaging for Early Detection of Gastric Cancer

Abstract

Gastric tumors are still late diagnosed and represent min. 17% of cases leading to metastasis. The ability to visualize the mucosa of the gastrointestinal tract in detail is a requisite for early detection of dysplasia and cancer. Although techniques such as chromoendoscopy, high resolution and magnification endoscopy, narrow band imaging, auto-fluorescence imaging improve the visualization and detection of mucosal lesions, biopsy of the targeted lesion must still be performed for a formal histological diagnosis of cellular and architectural atypical.
