Pseudo-CT generation from multiple MR images for small animal irradiation

Gutierrez Diaz S., Van Holen R., Descamps B., Vanhove C.

Introduction. Computed tomography (CT) is the standard imaging modality for radiation therapy treatment planning (RTTP) because of its ability to provide information on electron density. However, magnetic resonance (MR) imaging provides superior soft tissue [...]

A novel atlas-selection approach for multi-atlas based segmentation using the correlation of inter-atlas similarities

Raudaschl P., Fritscher K., Zaffino P., Sharp G., Spadea M., Schubert R.

Automated segmentation is a frequently applied task in the course of medical imaging. Furthermore, it is a substantial component of image-guided radiotherapy. Atlas based segmentation is one of the most frequently used approach for automated segmentation. [...]

Multimodal Analysis of Vasogenic Edema in Glioblastoma Patients for Radiotherapy Planning

Lê M., Delingette H., Kalpathy-Cramer J., Gerstner E., Shih H., Batchelor T., Unkelbach J., Ayache N.

Glioblastoma (GBM) is the most common type of primary brain tumor, which is characterized by an infiltrative growth pattern. In current practice, radiotherapy planning is primarily based upon T2 FLAIR MRI despite its known lack of specificity in the detection [...]

Validation of real-time intensity based 2D/3D registration for image guided radiotherapy

Furtado H., Underwood T., Depuydt T., Stock M., Georg D., Birkfellner W.

Patient motion during radiotherapy or intra-fractional motion, is one of the major sources of uncertainty in dose application. 2D/3D registration is an intensity based method used successfully to track tumor motion with the potential to reduce uncertainty. [...]

Deformable Registration with Discontinuity Preservation using Multi-Scale MRF

Seo D., Van Baar J.

Deformable (2D or 3D) medical image registration is a challenging problem. Existing approaches assume that the underlying deformation is smooth. This smoothness assumption allows for solving the deformable registration at a coarse resolution and interpolate [...]

Improvements in SlicerRT, the radiation therapy research toolkit for 3D Slicer

Pinter C., Lasso A., Wang A., Sharp G.C., Jaffray D., Fichtinger G.

Purpose: Recent years have seen growing interest in adaptive radiation therapy (RT), but the existing software tools are not ideal for research use, as they are either expensive and closed proprietary applications or free open-source packages with limited [...]

Gauss-Newton Method for Segmentation assisted Deformable Registration

Jurisic M., Fechter T., Hauler F., Furtado H., Nestle U., Birkfellner W.

In this work, we try to develop a fast converging method for segmentation assisted deformable registration. The segmentation step consists of a piece-wise constant Mumford-Shah energy model while reg- istration is driven by the sum of squared distances of [...]

Visualization of 4D-PET/CT, Target Volumes and Dose Distribution: Applications in Radiotherapy Planning

Schlachter M., Fechter T., Nestle U., Bühler K.

In radiation treatment (RT) planning medical doctors need to consider a variety of information sources for anatomical and functional target volume delineation. The validation and inspection of the defined target volumes and the resulting RT plan is a complex [...]

Automatic accuracy measurement for multi-modal rigid registration using feature descriptors

Hauler F., Jurisic M., Furtado H., Sabatini U., Laprie A., Nestle U., Birkfellner W.

In radiotherapy (RT) for tumor delineation and diagnostics, complementary information of multi-modal images is used. Using high ionizing radiation, the accuracy of registered volume data is crucial; therefore a reliable and robust evaluation method for [...]
