The p- posaltohostMICCAI2004wasstronglyencouragedandsupportedbyIRISA, Rennes. IRISA is a publicly funded national research laboratory with a sta? of 370,including150full-timeresearchscientistsorteachingresearchscientistsand 115 postgraduate students. INRIA, the CNRS, and the University of Rennes 1 are all partners in this mixed research unit, and all three organizations were helpful in supporting MICCAI. MICCAI has become a premier international conference with in-depth - pers on the multidisciplinary ?elds of medical image computing, comput- assisted intervention and medical robotics. The conference brings together cl- icians, biological scientists, computer scientists, engineers, physicists and other researchers and o?ers them a forum to exchange ideas in these exciting and rapidly growing ?elds. The impact of MICCAI increases each year and the quality and quantity of submitted papers this year was very impressive. We received a record 516 full submissions (8 pages in length) and 101 short communications (2 pages) from 36 di?erent countries and 5 continents (see ?gures below). All submissions were reviewed by up to 4 external reviewers from the Scienti?c Review C- mittee and a primary reviewer from the Program Committee. All reviews were then considered by the MICCAI 2004 Program Committee, resulting in the acceptance of 235 full papers and 33 short communications.

DOWNLOAD EBOOKThis monograph brings forth biomechanical research methods and outcomes on human tissue experiments such as those of the brain and the heart under a single umbrella. Different mechanical characterization techniques employed in human tissue property estimation are presented in detail. The contents also focus on a hyperelastic constitutive model (e.g., Mooney-Rivlin, Ogden) for both isotropic and anisotropic tissue characterization. It also discusses energy dissipation in soft tissues and associated viscoelasticity. Human tissues, including skin, muscles, connective tissues, and tissues in all functional organs are listed and their mechanical properties are presented in detail. These tissue properties are indispensable for computational modeling of biological systems, validation of biomechanical tissue testing, medical simulation through development of artificial phantoms and surrogates, and testing of medical devices and interventions. This book will serve as a key reference forresearch in tissue engineering & biomedical engineering, medical simulation, biomechanics, finite element modeling of biological systems, biomaterials, biotechnology, implant and medical device development, and healthcare wearables.

DOWNLOAD EBOOK"Tissue characterization is a major step in tissue mechanobiological studies. By characterization methods, tissue quality i.e. the combination of tissue structural, compositional and mechanical properties, is determined. This research focuses on mechanical characterization methods. Among all mechanical characterization methods, we propose those ones which are: 1) Non-destructive, (i.e. that reserves the capability of doing other characterization tests at the end of mechanical test; and, 2) In-line, (that enables tissue progression observation during experiment, and without transferring the specimen from one apparatus to another). However, in-line characterization raises the question of whether conducting tissue observation methods during experimentation modifies tissue progression over time. Therefore, the purpose of this study was to deepen our knowledge about the parameters which could affect tissue quality during mechanical testing. This requires a better understanding of viscoelasticity and viscoplasticity, two key behaviors of tissue, affecting the impact of these parameters (e.g. tissue quality, stimulation parameters) on the response of live tissue to biophysical stimuli. Thus, the objectives of this study were: 1. To review the literature to find information about two mechanical behaviors of tissue i.e. viscoelasticity and viscoplasticity, and the way they affect tissue properties 2. To investigate whether diagnostic tests, as mechanical characterization tests to observe tissue properties, affect tissue progression We explain that viscoelasticity and viscoplasticity of tissue originate from structure and components of the extracellular matrix. We also describe the way they affect tissue dynamic competition between repair, enzymatic degradation and mechanical degradation of the extracellular matrix. Moreover, we specify some tissue stimulation parameters, such as stimulation control type or stimulus history, which could affect tissue progression in response to biophysical stimuli because of viscoelasticity and viscoplasticity. Moreover, by conducting a series of 3-day experiments on freshly extracted tendons, we investigated whether applying "stress relaxation" tests at physiological amplitudes affects tissue response. We divided the tendons into two groups based on the characterization protocol (24 and 0 stress relaxation tests each day), and compared the progression of these groups over time. The stress relaxation tests at physiological amplitude modified tissue response to mechanical stimuli in vitro . In general, the modulus increased for 0 stress relaxation tests, while it first decreased and then increased slightly for 24 stress relaxation tests each day. The difference of mechanical properties between the two groups was significant. Therefore, applying stress relaxation tests at physiological amplitude during the rest periods between mechanical stimuli can affect live tissue progression over time. Therefore, it is essential to take into account the viscoelasticity and viscoplasticity of tissue while developing a stimulation protocol for bioreactor studies or clinical applications."

DOWNLOAD EBOOKTo capture the transient, nonlinear and time-dependent characteristics of the mechanical and material properties of biomaterials and biological tissue constructs, we developed a real-time based evaluation method. This method measures the paired transient stress and strain as a function of time for a given material, and calculates instantaneously its complex modulus measurements as a function of frequency. Because the measured complex moduli contain not only the mechanical properties (magnitude of the modulus curves) but also the material characteristics (shape of the modulus curves), this method allows us to link directly the mechanical properties to the material characteristics in a real-time and in-situ manner. The significance of this capability is that the changes in both mechanical property and material structure can be correlated repeatedly during the growing or aggregating processes of the biological tissues or constructs.

DOWNLOAD EBOOKThe motivation for writing aseries ofbooks on biomechanics is to bring this rapidly developing subject to students of bioengineering, physiology, and mechanics. In the last decade biomechanics has become a recognized disci pline offered in virtually all universities. Yet there is no adequate textbook for instruction; neither is there a treatise with sufficiently broad coverage. A few books bearing the title of biomechanics are too elementary, others are too specialized. I have long feIt a need for a set of books that will inform students of the physiological and medical applications of biomechanics, and at the same time develop their training in mechanics. We cannot assume that all students come to biomechanics already fully trained in fluid and solid mechanics; their knowledge in these subjects has to be developed as the course proceeds. The scheme adopted in the present series is as follows. First, some basic training in mechanics, to a level about equivalent to the first seven chapters of the author's A First Course in Continuum Mechanics (Prentice-Hall,lnc. 1977), is assumed. We then present some essential parts of biomechanics from the point of view of bioengineering, physiology, and medical applications. In the meantime, mechanics is developed through a sequence of problems and examples. The main text reads like physiology, while the exercises are planned like a mechanics textbook. The instructor may fil1 a dual role: teaching an essential branch of life science, and gradually developing the student's knowledge in mechanics.
