Thyroid Segmentation and Volume Estimation Using CT Images

ABSTRACT: Pathology of thyroid gland is determined by physicians with its volume as a significant indicator.For this thyroid area segmentation and volume estimation are necessary steps. Most physicians use CT images even if the volume of thyroid gland is determined using Ultrasound images, for precise evaluation of volume of thyroid gland. In this paper a Linear Vector Quantization neural network (LVQNN) with a pre-processing procedure and initial segmentation using cellular automata(CA) is proposed for thyroid segmentation and volume estimation using computerized tomography (CT) images
