Model-based Segmentation and Image Fusion of 3D Computed Tomography and 3D Ultrasound of the Eye for Radiotherapy Planning

Jean-Philippe Thiran, Meritxell Bach Cuadra, Subrahmanyam Venkata Ravi Mohana Sai Gorthi, Alessia Pica

For radiotherapy treatment planning of retinoblastoma in childhood, Computed Tomography (CT) represents the standard method for tumor volume delineation, despite some inherent limitations. CT scan is very useful in providing information on physical density ...

An Approach to Multimodal Image Segmentation

Dominique Zosso

Radiotherapy treatment planning requires exact delineation of tumors in acquired images. Further, motion and deformation of a tumor due to respiratory movements must be known in order to better target and dose the treatment radiation. Here we present and i ...

A Cross Validation Study of STN targeting on MRI: from Stereotactic Procedures and Automatic Registration Algorithms to direct identification

Jean-Philippe Thiran, Reto Meuli, Francisco Javier Sanchez Castro

Subthalamic nucleus (STN) Deep brain stimulation (DBS) has demonstrated its efficacy in the treatment of Parkinson´s disease. Accurate targeting of the STN is a crucial step for the success of DBS surgery. MRI has shown to be reliable and allows direct tar ...

Automatic Subthalamic Nucleus Targeting for Deep Brain Stimulation. A Validation Study

Jean-Philippe Thiran, Francisco Javier Sanchez Castro

In functional stereotactic neurosurgery, one of the cornerstones upon which the success and the operating time depends is an accurate targeting. The subthalamic nucleus (STN) is the usual target involved when applying Deep Brain Stimulation (DBS) for the P ...

Automatic Segmentation of Brain Structures for Radiation Therapy Planning

Valérie Duay, Benoît Macq

Delineation of structures to irradiate (the tumors) as well as structures to be spared (e.g., optic nerve, brainstem, or eyes) is required for advanced radiotherapy techniques. Due to a lack of time and the number of patients to be treated these cannot alw ...

Assessment of MR image deformation for stereotactic neurosurgery using a tagging sequence

David Lyndon Emsley

A tagging sequence is used to assess MR image deformations before a stereotactic neurosurgical procedure, in a test model and in two patients. This pulse sequence superimposes narrow parallel orthogonal tag lines on an image, which can be used as an intern ...

Comparison of CaF2 and LiF measurements of energy deposition rates in materials irradiated in a large 60Co facility

Rakesh Chawla

Energy deposition rates in various materials irradiated in a large 60Co facility have been measured using both CaF2 and LiF TLDs. Since the relationship between energy deposited in the TLD and that deposited in the surrounding medium (1/f factor) was diffe ...
