Download or read book Patient specific Interactive Ultrasound Image Simulation with Soft tissue Deformation written by Kresimir Petrinec and published by . This book was released on 2013 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasound imaging systems provide a low-cost, real-time, noninvasive and safe way to examine soft tissues inside the human body. Yet the ability of medical practitioners to understand and mentally register two-dimensional (2D) ultrasound image slices within the three-dimensional (3D) anatomy is a difficult task, so training is needed. Current ultrasound training methods are expensive, inefficient, and pose a major obstacle to the wide deployment of ultrasound imaging systems in routine clinical practice. In this thesis, we present a new approach to ultrasound training, where complex and expensive phantoms are replaced by a 3D virtual patient model, which represents the anatomy of any desired body part or organ and is simulated on a standard laptop computer. The advantage of our system is not only its cost effectiveness, but also its ability to emulate different disease states or conditions in different virtual patients and to visualize the underlying body structures of interest through different examination procedures with a virtual ultrasound probe. Conventional 3D models of the human body are purely geometric and do not model soft-tissue mechanics and deformation, which is an important factor in the practice of clinical ultrasound imaging. To address this limitation, we introduce real-time interactive soft tissue simulation in our 3D patient model. For this purpose, we adapt and evaluate two well-known deformable model simulation methods: mass-spring-damper systems (MSDS) and the finite element method (FEM) with a quasistatic solution of isotropic linear elastic materials with Cauchy strain. We apply these methods to the simulation of ultrasound in soft tissues. The soft tissue model in its undeformed state is determined by static real-patient data captured by applying a linear ultrasound probe on the neck and on the left upper arm. A visual tracking system is used to control the virtual probe. We achieve real-time interactive simulation rates by carefully adapting the code to run efficiently on multicore personal computers. Our real-time, interactive simulation of a 3D virtual patient with deformable soft tissues enables cheaper, more efficient, and more effective ultrasound training. Our ultrasound training system promises to facilitate the broader use of ultrasound in healthcare and reduce the number of medical procedure complications.
Download or read book Point of Care Ultrasound for the Field written by Saju Joseph and published by Nova Biomedical Books. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past few decades, point of care ultrasound (POCUS) has become standard in most emergency rooms and trauma bays. The use of POCUS has been shown to reduce mortality and morbidity while improving triage in critically ill patients. POCUS has also seen an increased use in hospitals as well. Anesthesiologists are using POCUS for line placement, regional blocks and now for endotracheal tube placement. In the ICU, POCUS is being used for most invasive procedures and in the diagnostic work up of patients. In the operating room, surgeons are using ultrasound to guide them during surgical procedures. Nursing staff have also incorporated ultrasound into their physical assessment of patients. POCUS allows visualization of internal structures and identification of pathology in real time with no deleterious effects for the patient. Recently, numerous medical schools including Harvard have developed dedicated curriculum for training medical students solely in the use of POCUS for physical exams. While this revolutionary training has not become the norm, the early data suggests that medical students trained in POCUS are better clinicians than their conventional counterparts. Will POCUS replace the stethoscope in the doctors handbag? The early data says yes. Until recently, the cost and training required to use POCUS has inhibited its expansion into the field. The cost for handheld units has decreased significantly in recent years and smartphones allow everyone the ability to carry a computer at all times. While training remains a hurdle, advances in technology and the overwhelming benefit it provides seems to have overcome this issue. Over the next decade, the editor predicts POCUS will become ubiquitous in all hospital areas and will see exponential growth in the prehospital setting. Currently, ultrasound guidance is standard for line placement and is increasingly being used for other bedside procedures. Furthermore, early trauma, sepsis, stroke and cardiac interventions have shown dramatic reduction in mortality and morbidity for all patients. Ultrasound imaging in the field allows for early triage, better use of limited resources, and better patient outcomes. These results will be the driver for POCUS use in the prehospital setting. This book is a hands-on field manual on the basic techniques of POCUS and the technical details that are required to incorporate POCUS for established first responders. The book also reviews the anatomy and physiology of many emergency situations while highlighting the role of POCUS in the treatment of the emergent patients. The authors include world experts in POCUS and have extensive experience in the development and use of POCUS in the field. In many situations, the authors provide tidbits from years of experience that may assist first responders in their job. Finally, the authors highlight many of the new techniques and technologies that continue to evolve that will change how POCUS is used in the future. We strongly recommend this book for all first responders and any person who is involved in patients in the prehospital setting or the emergency room. It is an excellent primer for anyone interested in learning how to perform ultrasounds or wanting to improve the outcomes for their patients.

Download or read book Enhancing PET Functionalities with Novel Geometries and Multimodal Imaging Techniques written by Suranjana Samanta and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positron emission tomography (PET) is a highly sensitive imaging modality that can provide in vivo quantitative information of biological processes at a biochemical level. The majority of PET systems have a ring geometry where the detectors fully encircle an axial section of a patient to provide whole-body imaging capability using multiple bed positions. However, these clinical whole-body PET systems are limited in terms of both image resolution and system sensitivity. To achieve a high resolution, customized geometries which trade global utility for application specific performance (breast, small animals etc.) imaging probes may be utilized. In some cases, an application-specific PET system can also significantly improve the system sensitivity, while in other cases new imaging capabilities are the main focus of a system design. Since these systems may have non-cylindrical geometries, they require a generalized reconstruction framework which is system geometry independent.To support the implementation of such PET systems with unconventional geometries, we have developed a fully 3D list-mode GPU based image reconstruction framework using maximum-likelihood expectation-maximization (ML-EM) algorithm. We have implemented correction procedures like normalization, attenuation correction and scatter correction for this image reconstruction framework to support arbitrary system geometry and interactive imaging using the PET/US system. We compare the performance of our framework with a clinical reconstruction framework. For all the systems investigated in our work, we have used this reconstruction framework. We also modified the framework to support continuous patient bed motion acquisition. Appropriate correction techniques (attenuation, scatter, normalization) for continuous bed motion need to be explored in future. We propose a high-performance dedicated breast PET imaging device concept which will scan both breasts simultaneously and have high sensitivity and resolution; fine temporal resolution; complete visualization of both breasts, mediastinum and axilla; and a modular design that can be inserted into a body MR scanner to provide dual-modality imaging (PET and MRI) allowing for MRI guided biopsy access. The volumetric geometry is illustrated along with GATE Monte Carlo simulations of various sized lesions (4-6mm) of differing lesion: background ratios (6:1 to 4:1) mimicking different biological uptake. We finally compare this dedicated breast PET imager to a state-of-the-art clinical PET/CT scanner. In another direction, we propose a novel PET/Ultrasound imaging system that will bring both these modalities to patient bedside to support point-of-care applications with near real-time interactive imaging capability. It consists of a movable hybrid imaging probe consisting of PET detector arrays and an ultrasound transducer. The PET detectors are in coincidence with a detector array behind a patient. The movable detectors make it possible for the operator to control the scanning trajectory freely to achieve optimal coverage and sensitivity for patient specific imaging tasks. The initial application is to detect vulnerable plaque in carotid artery using [64Cu]DOTA-ECL1i, a PET tracer targeting C-C chemokine receptor type 2 (CCR2) developed at Washington University which may identify high-risk plaques with inflammation. We present Monte Carlo simulation studies to test the feasibility of the system. We further optimize the system design, develop time-of-flight (TOF) PET detectors and develop a proof-of-concept POC PET/Ultrasound prototype. We perform phantom studies using this prototype and demonstrate the feasibility of this system to provide adequate anatomic, functional and molecular imaging information for carotid artery imaging. We also investigate another application of the POC PET technology to image lungs. Since, this is a stand-alone system targeted for imaging larger patient volumes, non-uniform tissue attenuation is a challenge. We implement a transmission-scan based attenuation correction and perform simulations to test this correction method with a known analytical æ-map based correction. We also report sensitivity and reconstructed phantom images as well as demonstrate an interactive scanning strategy. Finally, we discuss additional works needed to extend this list-mode reconstruction framework to support continuous-bed-motion acquisition in the future.

Download or read book Intraoperative Imaging and Image Guided Therapy written by Ferenc A. Jolesz and published by Springer Science & Business Media. This book was released on 2014-01-14 with total page 870 pages. Available in PDF, EPUB and Kindle. Book excerpt: Image-guided therapy (IGT) uses imaging to improve the localization and targeting of diseased tissue and to monitor and control treatments. During the past decade, image-guided surgeries and image-guided minimally invasive interventions have emerged as advances that can be used in place of traditional invasive approaches. Advanced imaging technologies such as magnetic resonance imaging (MRI), computed tomography (CT), and positron emission tomography (PET) entered into operating rooms and interventional suites to complement already-available routine imaging devices like X-ray and ultrasound. At the same time, navigational tools, computer-assisted surgery devices, and image-guided robots also became part of the revolution in interventional radiology suites and the operating room. Intraoperative Imaging and Image-Guided Therapy explores the fundamental, technical, and clinical aspects of state-of the-art image-guided therapies. It presents the basic concepts of image guidance, the technologies involved in therapy delivery, and the special requirements for the design and construction of image-guided operating rooms and interventional suites. It also covers future developments such as molecular imaging-guided surgeries and novel innovative therapies like MRI-guided focused ultrasound surgery. IGT is a multidisciplinary and multimodality field in which teams of physicians, physicists, engineers, and computer scientists collaborate in performing these interventions, an approach that is reflected in the organization of the book. Contributing authors include members of the National Center of Image-Guided Therapy program at Brigham and Women’s Hospital and international leaders in the field of IGT. The book includes coverage of these topics: - Imaging methods, guidance technologies, and the therapy delivery systems currently used or in development. - Clinical applications for IGT in various specialties such as neurosurgery, ear-nose-and-throat surgery, cardiovascular surgery, endoscopies, and orthopedic procedures. - Review and comparison of the clinical uses for IGT with conventional methods in terms of invasiveness, effectiveness, and outcome. - Requirements for the design and construction of image-guided operating rooms and interventional suites.
