Available in PDF, EPUB and Kindle. Book excerpt: Computer-aided minimally invasive surgery (MIS) has progressed significantly in the last decade and it has great potential in surgical planning and operations. To limit the damage to nearby healthy tissue, accurate modeling is required of the mechanical behavior of a target soft tissue subject to surgical manipulations. Therefore, the study of soft tissue deformations is important for computer-aided (MIS) in surgical planning and operation, or in developing surgical simulation tools or systems. The image acquisition facilities are also important for prediction accuracy. This dissertation addresses partial differential and integral equations (PDIE) based biomechanical modeling of soft tissue deformations incorporating the specific material properties to characterize the soft tissue responses for certain human interface behaviors. To achieve accurate simulation of real tissue deformations, several biomechanical finite element (FE) models are proposed to characterize liver tissue. The contribution of this work is in theoretical and practical aspects of tissue modeling. High resolution imaging techniques of Micro Computed Tomography (Micro-CT) and Cone Beam Computed Tomography (CBCT) imaging are first proposed to study soft tissue deformation in this dissertation. These high resolution imaging techniques can detect the tissue deformation details in the contact region between the tissue and the probe for small force loads which would be applied to a surgical probe used. Traditional imaging techniques in clinics can only achieve low image resolutions. Very small force loads seen in these procedures can only yield tissue deformation on the few millimeters to sub-millimeter scale. Small variations are hardly to detect. Furthermore, if a model is validated using high resolution images, it implies that the model is true in using the same model for low resolution imaging facilities. The reverse cannot be true since the small variations at the sub-millimeter level cannot be detected. In this dissertation, liver tissue deformations, surface morphological changes, and volume variations are explored and compared from simulations and experiments. The contributions of the dissertation are as follows. For liver tissue, for small force loads (5 grams to tens of grams), the linear elastic model and the neo-Hooke's hyperelastic model are applied and shown to yield some discrepancies among them in simulations and discrepancies between simulations and experiments. The proposed finite element models are verified for liver tissue. A general FE modeling validation system is proposed to verify the applicability of FE models to the soft tissue deformation study. The validation of some FE models is performed visually and quantitatively in several ways in comparison with the actual experimental results. Comparisons among these models are also performed to show their advantages and disadvantages. The method or verification system can be applied for other soft tissues for the finite element analysis of the soft tissue deformation. For brain tissue, an elasticity based model was proposed previously employing local elasticity and Poisson's ratio. It is validated by intraoperative images to show more accurate prediction of brain deformation than the linear elastic model. FE analysis of brain ventricle shape changes was also performed to capture the dynamic variation of the ventricles in author's other works. There, for the safety reasons, the images for brain deformation modeling were from Magnetic Resonance Imaging (MRI) scanning which have been used for brain scanning. The measurement process of material properties involves the tissue desiccation, machine limits, human operation errors, and time factors. The acquired material parameters from measurement devices may have some difference from the tissue used in real state of experiments. Therefore, an experimental and simulation based method to inversely evaluate the material parameters is proposed and compared with the material parameters measured by devices. As known, the finite element method (FEM) is a comprehensive and accurate method used to solve the PDIE characterizing the soft tissue deformation in the three dimensional tissue domain, but the computational task is very large in implementation. To achieve near real time simulation and still a close solution of soft tissue deformation, region-of-interest (ROI) based sub-modeling is proposed and the accuracy of the simulated deformations are explored over concentric regions of interest. Such a ROI based FE modeling is compared to the FE modeling over the whole tissue and its efficiency is shown and as well as its influence in practical applications such as endoscopic surgical simulation.

This book was released on 2012-04-27 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the biomechanical modeling of biological tissues in the context of Computer Assisted Surgery (CAS). More specifically, deformable soft tissues are addressed since they are the subject of the most recent developments in this field. The pioneering works on this CAS topic date from the 1980's, with applications in orthopaedics and biomechanical models of bones. More recently, however, biomechanical models of soft tissues have been proposed since most of the human body is made of soft organs that can be deformed by the surgical gesture. Such models are much more complicated to handle since the tissues can be subject to large deformations (non-linear geometrical framework) as well as complex stress/strain relationships (non-linear mechanical framework). Part 1 of the volume presents biomechanical models that have been developed in a CAS context and used during surgery. This is particularly new since most of the soft tissues models already proposed concern Computer Assisted Planning, with a pre-operative use of the models. Then, the volume addresses the two key issues raised for an intra-operative use of soft tissues models, namely (Part 2) “how to estimate the in vivo mechanical behavior of the tissues?” (i.e. what are the values of the mechanical parameters that can deliver realistic patient-specific behavior?) and (Part 3) “how to build a modeling platform that provides generic real-time (or at least interactive-time) numerical simulations?”

Book excerpt: The 1999 international conference on Information Processing in Medical Imaging (IPMI ’99) was the sixteenth in the series of biennial meetings and followed the successful meeting in Poultney, Vermont, in 1997. This year, for the rst time, the conference was held in central Europe, in the historical Hungarian town of Visegr ad, one of the most beautiful spots not only on the Danube Bend but in all Hungary. The place has many historical connections, both national and international. The castle was once a royal palace of King Matthias. In the middle ages, the Hungarian, Czech, and Polish kings met here. Recently, after the summit meeting of reestablished democracies in the area, it became a symbol for the cooperation between central European countries as they approached the European Union. It was thus also symbolic to bring IPMI, in the year of the 30th anniversary of its foundation, to this place, and organize the meeting with the close cooperation of local and traditional western organizers. It also provided a good opportunity to summarize brie?y a history of IPMI for those who were new to the IPMI conference. This year we received 82 full paper submissions from all over the world. Of these, 24 were accepted as oral presentations. These were divided into 6 sessions. In spite of our e orts, it was found to be impossible to make these sessions fully balanced and homogeneous.

Book excerpt: Finite element analysis (FEA) can potentially be used to predict soft tissue motion for the purpose of elasticity reconstruction and data fusion applications. For a simple phantom that simulated a soft tissue, FEA accurately predicted motion for surface deformations on the order of 11%. A computer controlled Magnetic Resonance (MR) compatible compression apparatus provided precise, time varying compression to a phantom. The motion of the phantom was measured with MR by acquiring velocity images throughout the cycle of compression. The phantom geometry was modeled with a finite element mesh and the mechanical properties of the phantom material were measured and incorporated in the finite element model. A static deformation was applied to the finite element model of the phantom and the internal motion was calculated. The motion as calculated by the finite element analysis was compared to the motion measured with MR and there was good agreement.

Available in PDF, EPUB and Kindle. Book excerpt: The combination of readily available computing power and progress in numerical techniques has made nonlinear systems - the kind that only a few years ago were ignored as too complex - open to analysis for the first time. Now realistic models of living systems incorporating the nonlinear variation and anisotropic nature of physical properties can be solved numerically on modern computers to give realistically usable results. This has opened up new and exciting possibilities for the fusing of ideas from physiology and engineering in the burgeoning new field that is biomechanics. Computational Biomechanics presents pioneering work focusing on the areas of orthopedic and circulatory mechanics, using experimental results to confirm or improve the relevant mathematical models and parameters. Together with two companion volumes, Biomechanics: Functional Adaptation and Remodeling and the Data Book on Mechanical Properties of Living Cells, Tissues, and Organs, this monograph will prove invaluable to those working in fields ranging from medical science and clinical medicine to biomedical engineering and applied mechanics.

This book was released on 2009 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: The simulations of grasping and cutting were performed on three types of tubular segment: surface, hollow and solid. Triangular and quadrilateral elements were used to mesh the surface type, while tetrahedral and hexahedral elements were used to mesh the hollow and solid types. Three different integration methods within FEM were used to calculate the deformation of the segment. The three integration methods were the static implicit, dynamic implicit, and dynamic explicit methods. In the simulation of grapsing the segment, it was found that the visual response of grasping was acceptable using the three integration methods. However, the computational time of grasping the segment using the dynamic explicit method was lower than the computational time using the static and dynamic implicit methods. Therefore, the explicit method is the preferred choice for performing the analysis of soft tissue deformation, and was used to simulate segment cutting. Using the explicit method, three different approaches were used to perform cutting on the virtual anatomy segment. In the first approach, a defined level of logarithmic strain was used to define elements to be deleted during simulated cutting. In this approach, cutting was performed by deleting elements with an isotropic elastic material property with and without defined cutting area (DCA). In the second approach, the cutting was simulated by deleting elements with a traction elastic material property with DCA. The elements were deleted in this approach because as they deformed, they lost their stiffness and caused failure of the elements, leading to degradation of the elements. In the third approach, the cutting of the segment was based on splitting the segment into two parts without the deletion of elements. It was found that these approaches produce an effective simulation of cutting a virtual anatomy segment for most of the three types of the segment in terms of visual response and computational time. The modeling carried out in this research suggests that FEM has significant potential to add realism to the virtual reality laparoscopic simulation and thus to enable the development of instrument-tissue manipulation skills in surgeons in training. In the case of grasping, FEM can clearly show the visual effect of deformation on the tissue grasped and the surrounding tissue. In relation to cutting, FEM can clearly show what is cut and how the surrounding tissue is affected.

Book excerpt: Biomechanics of Living Organs: Hyperelastic Constitutive Laws for Finite Element Modeling is the first book to cover finite element biomechanical modeling of each organ in the human body. This collection of chapters from the leaders in the field focuses on the constitutive laws for each organ. Each author introduces the state-of-the-art concerning constitutive laws and then illustrates the implementation of such laws with Finite Element Modeling of these organs. The focus of each chapter is on instruction, careful derivation and presentation of formulae, and methods. When modeling tissues, this book will help users determine modeling parameters and the variability for particular populations. Chapters highlight important experimental techniques needed to inform, motivate, and validate the choice of strain energy function or the constitutive model. Remodeling, growth, and damage are all covered, as is the relationship of constitutive relationships of organs to tissue and molecular scale properties (as net organ behavior depends fundamentally on its sub components). This book is intended for professionals, academics, and students in tissue and continuum biomechanics. Covers hyper elastic frameworks for large tissue deformations Considers which strain energy functions are the most appropriate to model the passive and active states of living tissue Evaluates the physical meaning of proposed energy functions
