Radiation therapy is one of the most effective options used in the treatment of about half of
all people with cancer. A critical goal in radiation therapy is to deliver optimal radiation …

Radiation therapy plays an important and effective role in the treatment of cancer. A main
goal in radiation therapy is to deliver high radiation doses to the perceived tumors while …

Segmentation is a crucial precursor to most medical image analysis applications. This paper
presents a new three-dimensional adaptive region growing algorithm for the automatic …

This paper presents a new method for shape based segmentation of 3D medical images. 3D
geometric information is calculated for each voxel by computing the partial derivatives of the …

This is a practical contouring method combining region growing, gradient edge detection,
and prior shape constraints to compute contours throughout a three dimensional, computed …

Segmentation for lung areas from CT images is an important task on understanding tissue
construction, computing and extracting abnormal areas. Many segmentation methods based …

A novel method for the automatic segmentation of the lung in X-ray computed tomography
(CT) images is presented. In this paper, a maximum a posteriori (MAP) estimation …

Computed tomography (CT) stands out among the exams used by computer-aided
diagnosis in medical imaging as it provides the visualization of internal organs such as the …

Segmentation of thoracic computed tomography (CT) images is an important step in many
medical imaging applications. This paper presents an automatic scheme for identifying the …
