This thesis presents a multimodal three-dimensional harp for interactive musical experiences for use in therapy for individuals with disabilities. A preliminary harp model in OpenGL with user interaction being a mouse and keyboard tested on special education children lead the Virtual Harp program on a new design approach to provide more interaction and stimuli. This system provides individuals ...

introduction: in diagnostic and therapeutic procedures, dosimetric studies are performed on the dosimetric systems in order to comply the radiation safety standards. monte carlo methods are used due to the high complexity and cost of patient-specific phantom construction. the high complexity of the digitized phantoms greatly increases the time and computational task of the monte carlo calculati...

Based on a distributed architecture for real-time collection and broadcast of haptic information to multiple participants, heterogeneous haptic devices (the PHANToM and the CyberGrasp) were used in an experiment to test the performance accuracy and sense of presence of participants engaged in a task involving mutual touch. In the experiment, the hands of CyberGrasp users were modeled for the co...

background: in nuclear medicine application often it is required to use computational methods for evaluation of organ absorbed dose. monte carlo simulation and phantoms have been used in many works before. the shape, size and volume in organs are varied, and this variation will produce error in dose calculation if no correction is applied. materials and methods: a computational framework for co...

In this paper, an efficient wearable glasses system is proposed for the application of preoperative spinal surgery. The technology is essential to generate a virtual space with a 3D model of the patient from CT images while marker attached [7]. The 3D model is then used to fit the poses of the phantom during surgery by using the PnP method. The patient’s preoperative 3-D image model is register...

The latest version of Leksell GammaPlan (LGP) is equipped with Digital Imaging and Communication in Medicine (DICOM) image-processing functions including image co-registration. Diagnostic magnetic resonance imaging (MRI) taken prior to Gamma Knife treatment is available for virtual treatment pre-planning. On the treatment day, actual dose planning is completed on stereotactic MRI or computed to...

This paper describes a new technique for allowing multiple users to haptically interact with a set of deformable slowly-simulated objects in a stable manner. Stability has been approached in the past by various researchers using passivity theory in order to avoid having to model the human operator closing the haptic loop. None of these solutions however can work well without the use of high upd...
