BACKGROUND Intensity-modulated radiotherapy (IMRT) may allow improvement in plan quality for treatment of liver cancer, however increasing radiation modulation complexity can lead to increased uncertainties and requirements for quality assurance. This study assesses whether target coverage and normal tissue avoidance can be maintained in liver cancer intensity-modulated radiotherapy (IMRT) plan...

A primary issue in the design of interactive art guides is the effort to build them as a synthesis of several cultures and skills concerning content editing, multimedia production, application structuring and interaction design. The communication between the actors of the development process can be boosted by involving the cultural domain experts in the whole life cycle, providing them with pro...

Context-awareness is an important capability needed in devices in a ubiquitous computing environment. Ubiquitous computing devices use different types of sensors along with the user’s interaction history in order to collect and store data. This data is then used to adapt the user’s behavior to suit the current environment. In addition to the explicit modifications by user control, the behavior ...

Introduction: Hypothyroidism is one of the frequent side effects of radiotherapy of head and neck cancers, breast cancer, and Hodgkin's lymphoma. It is recommended to estimate the normal tissue complication probability of thyroid gland using radiobiological modeling during treatment planning. Moreover, the use of artificial neural network is also proposed as a new method for t...

The main purposes of this study were to 1) investigate the dosimetric quality of uniform scanning proton therapy planning (USPT) for prostate cancer patients with a metal hip prosthesis, and 2) compare the dosimetric results of USPT with that of volumetric-modulated arc therapy (VMAT). Proton plans for prostate cancer (four cases) were generated in XiO treatment planning system (TPS). The beam ...

Purpose/Objective(s) Symptomatic postoperative radiotherapy-induced esophagitis (RE) (Grade≥2) develops in up to 31% of patients undergoing thoracic radiotherapy, lowering the quality life and sometimes leading treatment interruption, which negatively affects overall survival. We adopted common omics convolutional neural network (CNN) methods extract dosiomics features predict RE with ...

The position paper reports on our experiences with building an Eclipse based BSCW client called BSCWeasel. The client opens new opportunities for using the BSCW system, which was developed as a web-based groupware solution providing coordination support concepts like Shared Workspaces, Awareness Support, Community Support, etc. (see http://www.bscw.de/). It is an important goal of the BSCW appr...

To analyze the magnitude of setup errors corrected by helical tomotherapy megavoltage computed tomography (MVCT) on a daily or weekly basis and the impact of those corrections on the delivered dose to the tumor and organs at risk (OARs), we retrospectively analyzed the setup errors for 6 nasal cavity and 4 nasopharyngeal cancer patients treated with helical tomotherapy for 25 – 33 fractions. Ea...
