- A unifying framework for partial volume segmentation of brain MR imagesKoen Van Leemput
Medical Image Computing Radiology ESAT PSI, Faculty of Medicine, University Hospital Gasthuisberg, Leuven, Belgium
IEEE Trans Med Imaging 22:105-19. 2003..We conclude that general robust PV segmentation of MR brain images requires statistical models that describe the spatial distribution of brain tissues more accurately than currently available models...

- Probabilistic brain atlas encoding using Bayesian inferenceKoen Van Leemput
Helsinki Medical Imaging Center, Helsinki University Central Hospital, Finland
Med Image Comput Comput Assist Interv 9:704-11. 2006..We believe extracting optimal prior probability distributions from training data is crucial in light of the central role priors play in many automated brain MRI analysis techniques...
- A dosimetric study on the use of bolus materials for treatment of superficial tumors with BNCTTiina Seppälä
Boneca Corporation, P O B 700, FIN 00029 HUS, Helsinki, Finland
Appl Radiat Isot 61:787-91. 2004..A 5 mm paraffin bolus increases the surface dose approximately 50%, and its use may be advantageous for treatment of superficial tumors where the planning target volume (PTV) reaches to 6 cm or less in tissue depth...
