Describes innovative software for catheter localization and 3D reconstruction in stepping-source brachytherapy applications. The patient information is a set of computed tomography (CT) slices, scanned during the implantation of brachytherapy catheters. Catheter geometry and patient anatomy are exported for use with dose calculation software modules. The(More)
We developed a mobile teleconsultation system based on third-generation mobile phone links. The system comprised a laptop computer and a digital camcorder. It was installed inside an ambulance to allow video-conferencing between the moving vehicle and a doctor at a base station. In addition to video and voice, high-quality still images could also be(More)
Laparoscopy is an established method for the treatment of numerous surgical conditions. Natural orifice transluminal endoscopic surgery (NOTES) is a novel surgical technique that uses the natural orifices of the human body as entrances to the abdominal cavity. An alternative concept of minimally invasive approach to the abdominal cavity is to insert all the(More)
One of the main problems in public key infrastructures (PKI) is currently the lack of interoperability at international level, which is greatly dependent on the automation of the cross-certification procedure using certificate policies (CP). This paper addresses the aforementioned need by presenting a method for the automated development and comparison of(More)
Minimising the time required for a patient to receive primary care has always been the concern of the Accidents and Emergency units. Ambulances are usually the first to arrive on the scene and to administer first aid. However, as the time that it takes to transfer the patient to the hospital increases, so does the fatality rate. In this paper, a mobile(More)

in business domains requiring high level of customiza-tion and high level of portability like in the health domain. The approach discussed has been successfully used for the development of a large (in terms of complexity) client application in the financial domain. We are transferring the proposed approach to the health domain, having already developed an(More)
Multisensor image fusion is a process of combining information from multiple sensors. A newly non-invasive neurosurgical method that requires image fusion is the Gamma Knife. In this paper we present and evaluate advanced image fusion algorithms for Matlab platform and DICOM images helping efficiently the innovative Gamma Knife treatment planning. This(More)
Aim. Modular mini-robots can be used in novel minimally invasive surgery techniques like natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single site (LESS) surgery. The control of these miniature assistants is complicated. The aim of this study is the in silico investigation of a remote controlling interface for modular(More)
