Personalized radiotherapy treatment planning based on functional imaging

Functional imaging for radiotherapy treatment planning: current status and future directions—a review

In recent years, radiotherapy (RT) has been subject to a number of technological innovations. Today, RT is extremely flexible, allowing irradiation of tumours with high doses, whilst also sparing normal tissues from doses. To make use of these additional degrees of freedom, integration of functional image information may play a key role (i) for better staging and tumour detection, (ii) for more...

Towards Personalized Imaging in Image-guided Radiotherapy

Recently, with the advent of linear accelerators equipped with on-board x-ray images and advanced imaging technologies, image-guided radiotherapy (IGRT) has gained worldwide momentum in the radio therapeutic management of cancers in terms of volumetric information-based accurate tumor localization, real-time patient setup and margin reduction [1,2]. The involved technologies include digital rad...

Radiotherapy treatment planning

In radical radiotherapy treatment we aim to accurately deliver a lethal dose of radiation to tumour cells while sparing any surrounding normal tissues. Radiotherapy treatment planning is the process undertaken to determine the most appropriate way to deliver the radiation in order to meet the clinical prescription. Rapid advances in technology and computing, particularly in relation to imaging,...

PETCT in radiotherapy treatment planning

Partial differential equations-based segmentation for radiotherapy treatment planning.

The purpose of this study is to develop automatic algorithms for the segmentation phase of radiotherapy treatment planning. We develop new image processing techniques that are based on solving a partial diferential equation for the evolution of the curve that identifies the segmented organ. The velocity function is based on the piecewise Mumford-Shah functional. Our method incorporates informat...
