The problem addressed in this PhD thesis is how to offer an effective and efficient VR means of training in laparoscopic surgery. The question is to determine what makes it a useful didactic tool. This work is conceived to be a bridge between surgical tra

Doctoral Thesis / Dissertation from the year 2014 in the subject Medicine - Biomedical Engineering, grade: Excellent "cum laude", , language: English, abstract: Minimally invasive surgery (MIS) has become in many surgical specialties and procedures the gold-standard choice due to its efficiency and benefits towards patient safety. However, the introduction of laparoscopic surgery has led to the need of developing new surgical skills different to those required for open surgery, with a significant learning curve to perform a safe laparoscopic surgery. Traditional subjective assessment methods of trainees are no longer adequate for surgical training. Reduced working hours as well as demands from surgeons and associations mean that more objective assessment tools that can accredit surgeons as technically competent are required. Evidence exists to validate motion analysis for laparoscopic technical skills assessment. Motion analysis of the laparoscopic instruments seeks to determine aspects that indicate the difference between surgeon's level of surgical dexterity. However, at the moment there is not an extended method to be used with current available training systems used in training laboratories as well as for the OR. The purpose of this book is to present the design, development and validation of three novel motion analysis methods focused on the use of real laparoscopic instruments during laparoscopic performance. These methods are based on computer vision techniques attempting to not interfere with the surgical practice. They are introduced in an evolutionary way from methods for exclusive use in a box trainer to solutions with the potential of being used in actual OR setting. Overall, this work corroborates the research hypothesis regarding the use of three different video-based tracking technologies for motion analysis of laparoscopic instruments, the use of instrument motion analysis for MIS technical skills assessment and the relationship between motion-related assessment metrics and quality of technical performance in laparoscopic training. These presented methods provide a tool to objectively assess MIS technical performance and a support to train novice surgeons in MIS techniques. The findings of this work encourage us to continue researching in improving these methods to be introduced as part of an actual laparoscopic training program, both inside and outside the OR.

Technological advancement in graphics and other human motion tracking hardware has promoted pushing "virtual reality" closer to "reality" and thus usage of virtual reality has been extended to various fields. The most typical fields for the application of virtual reality are medicine and engineering. The reviews in this book describe the latest virtual reality-related knowledge in these two fields such as: advanced human-computer interaction and virtual reality technologies, evaluation tools for cognition and behavior, medical and surgical treatment, neuroscience and neuro-rehabilitation, assistant tools for overcoming mental illnesses, educational and industrial uses. In addition, the considerations for virtual worlds in human society are discussed. This book will serve as a state-of-the-art resource for researchers who are interested in developing a beneficial technology for human society.

The field of minimally invasive surgery (MIS) has now taken centre stage in modern clinical practice. With ever changing technologies in the field of MIS, such as robotics, there is now the need to train the surgeon to the next degree. Training by simulation, whether virtual, hybrid, or real, allows the surgeon to rehearse, learn, improve or maintain their skills in a safe and stress free environment. Simulation Training in Laparoscopy and Robotic Surgery gives a true insight into the latest educational and learning techniques for new technologies in surgery. Written by an international team of experts, this illustrated text provides advice on specialised team training, non technical skills and simulation. Simulation Training in Laparoscopy and Robotic Surgery is an important training aide for surgeons and residents interested in developing skills in this field.

This book provides a broad overview on training in Minimal Access Surgery, with expert opinions from leaders in the field clarifying the definitions and terminology related to competence and accreditation. It also provides expert advice on how to set up a training unit and explores the role and impact of all types of simulations on training including virtual reality simulation. How to design a competency-based training curriculum in advanced laparoscopic surgery is also explored along with in depth examination of the role of assessment and competency based accreditation. Training in Minimal Access Surgery is a valuable resource for all health care professionals who are involved in training and education in Minimal Access Surgery including trainers and supervisors. ​There is well established and robust evidence to support the benefits of laparoscopic surgery in terms of better pain control, fewer complications and shorter length of stay with an earlier return to work. Hence, there is now widespread adoption of laparoscopic techniques in many surgical specialties including colorectal and morbid obesity surgery across the world.

This book presents a comprehensive state-of the-art approach to digital health technologies and practices within the broad confines of healthcare practices. It provides a canvas to discuss emerging digital health solutions, propelled by the ubiquitous availability of miniaturized, personalized devices and affordable, easy to use wearable sensors, and innovative technologies like 3D printing, virtual and augmented reality and driverless robots and vehicles including drones. One of the most significant promises the digital health solutions hold is to keep us healthier for longer, even with limited resources, while truly scaling the delivery of healthcare. Digital Health: Scaling Healthcare to the World addresses the emerging trends and enabling technologies contributing to technological advances in healthcare practice in the 21st Century. These areas include generic topics such as mobile health and telemedicine, as well as specific concepts such as social media for health, wearables and quantified-self trends. Also covered are the psychological models leveraged in design of solutions to persuade us to follow some recommended actions, then the design and educational facets of the proposed innovations, as well as ethics, privacy, security, and liability aspects influencing its acceptance. Furthermore, sections on economic aspects of the proposed innovations are included, analyzing the potential business models and entrepreneurship opportunities in the domain.

tionship indicates how multimodal medical image processing can be unified to a large extent, e. g. multi-channel segmentation and image registration, and extend information theoretic registration to other features than image intensities. The framework is not at all restricted to medical images though and this is illustrated by applying it to multimedia sequences as well. In Chapter 4, the main results from the developments in plastic UIs and mul- modal UIs are brought together using a theoretic and conceptual perspective as a unifying approach. It is aimed at defining models useful to support UI plasticity by relying on multimodality, at introducing and discussing basic principles that can drive the development of such UIs, and at describing some techniques as proof-of-concept of the aforementioned models and principles. In Chapter 4, the authors introduce running examples that serve as illustration throughout the d- cussion of the use of multimodality to support plasticity.

Laparoscopic surgery has been established as a safe, effective approach in the management of colorectal disease. Compared with open surgery, laparoscopy is associated with decreased postoperative analgesia requirements, faster return of bowel function and resumption of oral intake, shorter hospital stay, and better cosmetic repair. Now in its second edition, this book gives surgeons the learning tools they need to understand and successfully incorporate laparoscopic colorectal surgery into their practice.
