Healthcare Built Environment and Telemedicine Practice for Social and Environmental Sustainability

The practice of telemedicine started at the beginning of the 20th century but has never been widely implemented, even though it is significantly sustainable compared to traveling to healthcare However, the ongoing COVID-19 pandemic pushed organisations and patients to accept this technology. During the pandemic, telemedicine consultations took place in ad hoc environments without much preparation and planning. As a result, there is a knowledge gap in the field between telemedicine’s clinical care services and healthcare built environment, in terms of design. This research focused on addressing the quality of service and experience of telemedicine in primary healthcare settings and how this could be influenced by the digital infrastructure. Our aim was to understand the correlations between telemedicine and healthcare built environment and whether the latter could have a significant impact on telemedicine practice. The methodology included interviews with professionals involved in healthcare planning, architecture and ethnography, and end user research involving telemedicine sessions. The interviews highlighted that professionals involved in the design of healthcare environments demonstrated limited consideration of telemedicine environments. Yet, the ethnographic, end-user research identified areas where the telemedicine environment could affect user experience and should be taken into consideration in the design of such spaces

Digital watermarking in medical images

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 05/12/2005.This thesis addresses authenticity and integrity of medical images using watermarking. Hospital Information Systems (HIS), Radiology Information Systems (RIS) and Picture Archiving and Communication Systems (P ACS) now form the information infrastructure for today's healthcare as these provide new ways to store, access and distribute medical data that also involve some security risk. Watermarking can be seen as an additional tool for security measures. As the medical tradition is very strict with the quality of biomedical images, the watermarking method must be reversible or if not, region of Interest (ROI) needs to be defined and left intact. Watermarking should also serve as an integrity control and should be able to authenticate the medical image. Three watermarking techniques were proposed. First, Strict Authentication Watermarking (SAW) embeds the digital signature of the image in the ROI and the image can be reverted back to its original value bit by bit if required. Second, Strict Authentication Watermarking with JPEG Compression (SAW-JPEG) uses the same principal as SAW, but is able to survive some degree of JPEG compression. Third, Authentication Watermarking with Tamper Detection and Recovery (AW-TDR) is able to localise tampering, whilst simultaneously reconstructing the original image

Innovative ICT solutions in telemedicine to support clinical practice and research in hospitals

2010/2011The scope of this study was to examine ICT telemedicine innovations and potentialities in web-portals, intranet services and tele-radiology topics respectively, in order to design, develop and, possibly, realize apposite telemedicine systems and solutions for healthcare and in particular for the hospitals. ICT techniques and technologies are nowadays applied in every area of our common living from work places to our homes, our free-time, schools, universities and so on. The healthcare services offered by hospitals are heavily supported by technologies and, behind them, by a wide research both in ICT and biomedical sciences. Thanks to these advances telemedicine is now becoming a fundamental part of services offered by hospitals and healthcare structures. The healthcare management, the doctors and the common people are now experimenting how telemedicine is an added value to all the services offered in terms of the quality of care, the patient follow up, the early diagnose and treatment of pathologies and diseases. In this research is presented an all-inclusive approach to telemedicine problems and challenges in particular studying, developing and proposing ICT methods and technologies in the above mentioned three areas of interest: •innovative healthcare and telemedicine-ready hospital website or portal design and development; •analysis and study of models for the realization of intranet healthcare services to enhance both quality of care and the management of healthcare personnel evaluation; •tele-radiology and some of its actual new perspectives as the study and the evaluation of the “mobile” tele-radiology approach using commercial tablets (and what it could mean).For the first topic the results may be summarized in the development of a more interactive and “social” hospital web-portal offering original solutions and services to all the categories of users (audience, professionals, researchers), allowing them – through the use of advanced tools - to configure and select their own pages and interests. The originality of this approach consists in a good cost/effective result in the respect of the last and worldwide accepted Internet regulations and policies too. A similar approach regarded the intranet services and the design of web interfaces for the clinical practice and the executive evaluation. These kind of innovative systems regard a limited and selected number of more skilled users, typically belonging to a corporation or to specific offices. As above the approach is important: interactive services, innovative tools and affordable instruments are the keywords of the systems designed or proposed to solve specific problems or needs. The last research topic concerned the proposal of a protocol for the assessment of medical images on commercial displays, interesting the stakeholders and the groups involved in medical images treatment, visualization and communication. The potentialities of the mobile tablet devices improve day after day and new devices are marketed every week and the innovation is round the corner. These potentialities must encounter the medical diagnostics world and meet the standards and the regulations the international community established. It will be difficult for a commercial tablet to obtain the medical device CE mark not only for commercial reasons, but the technical limits may be reached and even surpassed adopting objective measures and evaluations. This study demonstrates that commercial tablets may be used in clinical practice for the correct visualization and diagnose of medical images. The measures of some display characteristics may be considered acceptable for mobile interpretation (even report?) of medical images, but if and only if the ambient lighting conditions are under objective control and integrated automated systems in tablets warns physicians about bad or borderline technical and ambient restrictions or bonds.XXIII Ciclo197

TELMA: Technology enhanced learning environment for minimally invasive surgery

Background: Cognitive skills training for minimally invasive surgery has traditionally relied upon diverse tools, such as seminars or lectures. Web technologies for e-learning have been adopted to provide ubiquitous training and serve as structured repositories for the vast amount of laparoscopic video sources available. However, these technologies fail to offer such features as formative and summative evaluation, guided learning, or collaborative interaction between users. Methodology: The "TELMA" environment is presented as a new technology-enhanced learning platform that increases the user's experience using a four-pillared architecture: (1) an authoring tool for the creation of didactic contents; (2) a learning content and knowledge management system that incorporates a modular and scalable system to capture, catalogue, search, and retrieve multimedia content; (3) an evaluation module that provides learning feedback to users; and (4) a professional network for collaborative learning between users. Face validation of the environment and the authoring tool are presented. Results: Face validation of TELMA reveals the positive perception of surgeons regarding the implementation of TELMA and their willingness to use it as a cognitive skills training tool. Preliminary validation data also reflect the importance of providing an easy-to-use, functional authoring tool to create didactic content. Conclusion: The TELMA environment is currently installed and used at the Jesús Usón Minimally Invasive Surgery Centre and several other Spanish hospitals. Face validation results ascertain the acceptance and usefulness of this new minimally invasive surgery training environment

Digital Video Concepts, Methods, and Metrics: Quality, Compression, Performance, and Power Trade-off Analysis

Digital Video Concepts, Methods, and Metrics: Quality, Compression, Performance, and Power Trade-off Analysis is a concise reference for professionals in a wide range of applications and vocations. It focuses on giving the reader mastery over the concepts, methods and metrics of digital video coding, so that readers have sufficient understanding to choose and tune coding parameters for optimum results that would suit their particular needs for quality, compression, speed and power. The practical aspects are many: Uploading video to the Internet is only the beginning of a trend where a consumer controls video quality and speed by trading off various other factors. Open source and proprietary applications such as video e-mail, private party content generation, editing and archiving, and cloud asset management would give further control to the end-user. Digital video is frequently compressed and coded for easier storage and transmission. This process involves visual quality loss due to typical data compression techniques and requires use of high performance computing systems. A careful balance between the amount of compression, the visual quality loss and the coding speed is necessary to keep the total system cost down, while delivering a good user experience for various video applications. At the same time, power consumption optimizations are also essential to get the job done on inexpensive consumer platforms. Trade-offs can be made among these factors, and relevant considerations are particularly important in resource-constrained low power devices. To better understand the trade-offs this book discusses a comprehensive set of engineering principles, strategies, methods and metrics. It also exposes readers to approaches on how to differentiate and rank video coding solutions
