Abstract

Tumor volume is an import diagnostic and prognostic factor for tongue carcinoma (TC). Currently, tumor volume of TC is estimated by measuring the maximal diameter or depth of tumor, or by summing the areas which are manually traced by a radiologist, from the surgical resections or multi-images of CT and MRI [1-2]. However, these methods are not accurate and in addition, not objective. In this study, a semi-automated region deformation (RD)-based algorithm was introduced to segment TC from MR images and volumes of 10 TC cases were measured.
