Book Description
The ability to negate tissue motion without complex physical constraints would greatly benefit beating heart surgery, procedures where respiration causes tissue movement, and in the case of physically unstable operating environments such as a battlefield, moving vehicle, or space station. Using a calibrated stereo camera, it is possible to measure the 3D position of an object with relation to any known frame, and subsequently its motion. A method has been developed and implemented with the RAVEN TM1 surgical research robot for tracking and compensating for tissue motion with the goal of uncovering future research directions which will lead to real-time implementation of this technology. Results reveal insights regarding algorithm optimization, robot hardware limits, and the likelihood that the methods used are capable of operating in real-time with adequate computer hardware utilization.

Book Description
In minimally invasive heart bypass surgery, the surgeon performs tasks while he/she is seated at the console and can see inside the body via an image provided by the camera. In this type of surgery, heart beating is an important issue. Consequently, the idea of developing a motion compensation robotic system in which the robot synchronizes the surgical tool with heart motion, giving the surgeon the impression of a virtually stable tissue, is promising. However, developing an appropriate heart surface tracking algorithm remains a challenging task. To track heart motion a vision-based approach used in this work that track motion of some natural features on the heart surface. However the question arises: which features should be tracked? So far in the majority of the proposed methods, feature selection is accomplished by manually selecting some features. However in practice, it is highly possible that selected features by a surgeon could not be capable of being tracked for a reasonable amount of time. To overcome this problem, this work presents an algorithm for automatic tracking of features on the human heart. The key contributions of the proposed algorithm are uniform distribution of the features and sustained tolerable tracking error. We selected a data-driven detection stage, which works based on the feedback from tracking results from Lucas-Kanade algorithm. To ensure a uniform spatial distribution of the total detected features, a cost function is employed using the simulated annealing optimizer, which prevents the newly-detected points from accumulating near the previously-located points or stagnant regions. The results of implementing the proposed algorithm on a real human heart data set show the presented algorithm yields more robust tracking and improved motion reconstruction. Furthermore, to predict the motion of features for handling short-term occlusions a state space model is utilized, and Thin-Plate Spline interpolation was also employed to estimate motion of any arbitrary point on the heart surface. Finally, a Model Reference Adaptive Control, based on Neural Network, is implemented on a three translational manipulator and motion of the robot synchronized with motion of the heart surface to achieve a motion compensation robotic system.

Book Description
A predictive tracking approach and a novel method for visual motion compensation are introduced, which accurately reconstruct and compensate the deformation of the elastic object, even in the case of complete measurement information loss. The core of the methods involves a probabilistic physical model of the object, from which all other mathematical models are systematically derived. Due to flexible adaptation of the models, the balance between their complexity and their accuracy is achieved.

Book Description
The first generation of surgical robots are already being installed in a number of operating rooms around the world. Robotics is being introduced to medicine because it allows for unprecedented control and precision of surgical instruments in minimally invasive procedures. So far, robots have been used to position an endoscope, perform gallbladder surgery and correct gastroesophogeal reflux and heartburn. The ultimate goal of the robotic surgery field is to design a robot that can be used to perform closed-chest, beating-heart surgery. The use of robotics in surgery will expand over the next decades without any doubt. Minimally Invasive Surgery (MIS) is a revolutionary approach in surgery. In MIS, the operation is performed with instruments and viewing equipment inserted into the body through small incisions created by the surgeon, in contrast to open surgery with large incisions. This minimizes surgical trauma and damage to healthy tissue, resulting in shorter patient recovery time. The aim of this book is to provide an overview of the state-of-art, to present new ideas, original results and practical experiences in this expanding area. Nevertheless, many chapters in the book concern advanced research on this growing area. The book provides critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies. This book is certainly a small sample of the research activity on Medical Robotics going on around the globe as you read it, but it surely covers a good deal of what has been done in the field recently, and as such it works as a valuable source for researchers interested in the involved subjects, whether they are currently “medical roboticists” or not.

Book Description
Compensating for Quasi-periodic Motion in Robotic Radiosurgery outlines the techniques needed to accurately track and compensate for respiratory and pulsatory motion during robotic radiosurgery. The algorithms presented within the book aid in the treatment of tumors that move during respiration. In Chapters 1 and 2, the book introduces the concept of stereotactic body radiation therapy, motion compensation strategies and the clinical state-of-the-art. In Chapters 3 through 5, the author describes and evaluates new methods for motion prediction, for correlating external motion to internal organ motion, and for the evaluation of these algorithms’ output based on an unprecedented amount of real clinical data. Finally, Chapter 6 provides a brief introduction into currently investigated, open questions and further fields of research. Compensating for Quasi-periodic Motion in Robotic Radiosurgery targets researchers working in the related fields of surgical oncology, artificial intelligence, robotics and more. Advanced-level students will also find this book valuable.

Book Description
An important obstacle in Minimally Invasive Surgery (MIS) is the significant degradation of haptic feedback (sensation of touch) to the surgeon about surgical instrument's interaction with tissue. This monograph is concerned with devices and methods required for incorporating haptic feedback in master-slave robotic MIS systems. In terms of devices, novel mechanisms are designed including a surgical end-effector (slave) with full force sensing capabilities and a surgeon-robot interface (master) with full force feedback capabilities. Using the master-slave system, various haptic teleoperation control schemes are compared in terms of stability and performance, and passivity-based time delay compensation for haptic teleoperation over a long distance is investigated. The monograph also compares haptic feedback with visual feedback and with substitution for haptic feedback by other sensory cues in terms of surgical task performance.

Book Description
In robotic beating heart surgery, a remote-controlled robot can be used to carry out the operation while automatically canceling out the heart motion. The surgeon controlling the robot is shown a stabilized view of the heart. First, we consider the use of directional statistics for estimation of the phase of the heartbeat. Second, we deal with reconstruction of a moving and deformable surface. Third, we address the question of obtaining a stabilized image of the heart.
