Background. Long span is seen in many clinical situations. Treatmentplanning options of these cases are difficult and may require FPD, RPD or ISP. Each option has its own disadvantages, including mechanical problems, patient comfort and cost. This article will evaluate the stress distribution of a different treatment option, which consists of adding a single sup-porting implant to the FPD by us...

CHEN-RUI CHOU: REGRESSION LEARNING FOR 2D/3D IMAGE REGISTRATION. (Under the direction of Stephen M. Pizer.) Image registration is a common technique in medical image analysis. The goal of image registration is to discover the underlying geometric transformation of target objects or regions appearing in two images. This dissertation investigates image registration methods for lung Image-Guided R...

PURPOSE The increasing complexities of the geometry of 3D radiation treatment plans possess challengesto the monitor unit (MU) and dose verification in clinical routine. In this work, the commissioningof the DIAMOND software (PTW-Freiburg Germany) for two Siemens linear accelerators(Primus & Artiste) along with the evaluation of its performance is described. METHODS DIAMOND employs the modifi...

OBJECTIVE The objective of this study was to evaluate the facial attractiveness in 30 black individuals, according to the Subjective Facial Analysis criteria. METHODS Frontal and profile view photographs of 30 black individuals were evaluated for facial attractiveness and classified as esthetically unpleasant, acceptable, or pleasant by 50 evaluators: the 30 individuals from the sample, 10 or...

Introduction: This study was aimed to investigate the beneficial effects of functional magnetic resonance imaging (fMRI) data in treatment planning for patients with CNS tumors in order to decrease the injury of functional regions of the brain followed by increase in life quality and survival of patients. This study pursues a novel approach in planning for the treatment of brai...

Boron neutron capture therapy (BNCT) is a biologically targeted radiotherapy modality. So far, 249 cancer patients have received BNCT at the Finnish Research Reactor 1 (FiR 1) in Finland. The effectiveness and safety of radiotherapy are dependent on the radiation dose delivered to the tumor and healthy tissues, and on the accuracy of the doses. At FiR 1, patient dose calculations are performed ...

Dental Implant Cone Beam Scans of Older Individuals Often Reveal Potentially Life-Threatening Atherosclerotic Disease T use of cone beam computed tomography (CBCT) by dentists has enhanced the treatmentplanning process for selecting optimal sites within the mandible and maxilla for successful implant placement. Large field of view CBCT units do, however, image anatomical structures beyond the j...
