In this chapter, we introduce a near-field coded aperture imaging technique and 3D image reconstruction methods for high sensitivity and high resolution single photon emission computerized tomography (SPECT). For tomographic data acquisition, the optoacoustically generated waves are detected on a surface surrounding the imaged region. The nonlinear support vector classifier (SVC) achieved slightly higher classification accuracy (88.4%) than the other classifiers. A phase-based geodesic active contour (GAC) is implemented to refine the boundaries in finer pyramid levels. The experimental results have demonstrated the feasibility of the 3D reconstruction algorithm in coded aperture imaging for high sensitivity and high resolution SPECT systems.

We quantitate the inherent ambiguities in the measured phase, for a given acquisition strategy. It is very time consuming and sometimes infeasible to re-construct the shape dictionary every time new training shapes appear. However, they require significant changes in the algorithmic designing compared to traditional programming paradigms. The framework is based on active contours and exploits both local intensity and local phase features to deal with degradations of ultrasound images such as low signal-to-noise, intensity inhomogeneity and speckle noise. Our in vivo results demonstrate substantially improved performance as compared to existing techniques. We compared the performance of seven classical and state-of-the-art classifiers. This chapter reviews a selection of minimally invasive imaging and sensing technologies used in the treatment of patients with coronary artery and valvular heart diseases. Model-based image-reconstruction techniques represent an alternative approach to solving the inverse problem that can significantly reduce image artifacts associated with approximated analytical formulae and significantly enhance image quality in non-ideal imaging scenarios.

Presently, 4.7B individuals around the globe don’t access to this fundamental innovation. 4 0 obj The accurate segmentation of subcortical brain structures in magnetic resonance (MR) images is of crucial importance in the interdisciplinary field of medical imaging. The duration of the scan affects image quality and patient throughput but, perhaps more importantly, faster data acquisition also enables novel MRI applications which are infeasible under current data acquisition rates. Vision-Based Robotic Learning of Language Research done by UW CSE student Aaron Shon Robot learns names for new objects through gaze following . It … The proposed direct frame interpolation (DFI) method creates additional intermediate image frames by directly interpolating between two or more adjacent image frames of the series of high resolution ultrasound B-mode image frames (an image series). Our results show that this is a promising approach to achieving fully automated segmentation with accuracy comparable to manual segmentation. This theme attempts to address the improvement and new techniques on the analysis methods of medical image. Pathologists have practiced medicine in a relatively unchanged manner over the last century to render the diagnosis of disease. First, since SSC involves an iterative sparse optimization at run-time, the more shape instances contained in the repository, the less run-time efficiency SSC has. Loading … Therefore, a compact and informative shape dictionary is preferred to a large shape repository. However, such distribution measures are non-linear (higher-order) functionals, which can be difficult to optimize. Using the huge amount of ultrasound images to train the medical imaging application, computer-vision ultrasound system can show more comprehensive results with accuracy, that usually analyzed by the radiologists. endobj S. Monti et al. Therefore, image coregistration has become crucial both for qualitative visual assessment and for quantitative multiparametric analysis in research applications. And if such models are trained with more accurate data, it will significantly enhance the level of accuracy in medical imaging analysis through machine learning. In the model-based reconstruction, a linear forward model is constructed to accurately describe the experimental conditions of the imaging setup. Experiments performed on an 8-object structure defined in axial cross sectional MR brain images show that the new hierarchical segmentation significantly improves the accuracy of the segmentation, and while it exhibits a remarkable robustness with respect to the size of the training set. Next, we propose a solution which achieves robust estimates over large dynamic range of phase values, at very high spatial resolutions. The DFI method can be considered as a valuable alternative to conventional 3-D ultrasound reconstruction methods based on pixel or a voxel nearest neighbor approaches, offering better quality and competitive reconstruction time. The major progress in computer vision allows us to make extensive use of medical imaging data to provide us better diagnosis, treatment and predication of diseases. E(�1�I����B�ә�'A2d���͸�-eX�SG4,����i!���m�)�Oi��I��=����n��`%= g�B0f It has been investigated extensively in two-dimensional (2D) planar objects in the past, whereas little success has been achieved in three-dimensional (3D) object imaging using this technique. First, integration of multimodal information carried out from different diagnostic imaging techniques is essential for a comprehensive characterization of the region under examination. The chapter further discusses the usefulness of distribution-matching techniques in various medical image segmentation scenarios, and includes examples from cardiac, spine and brain imaging. It has been a challenge to use computer vision in medical imaging because of complexity in dealing with medical images. The final objective is to benefit the patients without adding to the already high medical costs. Instead of assuming any parametric model of shape statistics, SSC incorporates shape priors on-the-fly by approximating a shape instance (usually derived from appearance cues) by a sparse combination of shapes in a training repository. X-ray angiography and intracoronary imaging such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) document coronary anatomy from different perspectives. Its solutions depend on the best in class computer vision, deep learning and artificial intelligence innovation. Computer Vision means giving machines not only eyes, but the reasoning skills necessary to help medical professionals with their diagnoses. However, this strategy confronts two limitations in practice. Chapter 1: An Introduction to Computer Vision in Medical Imaging (415 KB),, In the recent years, graphics processing units (GPU) have become a new tool for computing, offering the processing power of yesterday's supercomputers. Intravascular Ultrasound (IVUS) has been established as a useful tool for diagnosis of coronary heart disease (CHD). <>/Metadata 73 0 R/ViewerPreferences 74 0 R>> ))N��S� $��a��d�)�|���p`�? Recent developments have opened the possibility of using IVUS to create a 3D map from which preventative prediction of CHD can be attempted. A common class of “spatial phase regularization” algorithms, such as phase unwrapping and de-noising, attempt to resolve these ambiguities. Medical imaging Image guided surgery Grimson et al., MIT 3D imaging MRI. However, the accuracy of the segmentation is still not adequate for clinical use. While most of the cases in clinical practice, the retinal images produced are quite clean and easily used by the ophthalmologists, there are many cases in which these images come out to be very blurred due to ocular opacities such as cataract, vitritis etc. Compared to traditional gradient-based GAC methods, the phase-based model is more suitable for ultrasound images with low contrast and weak boundaries. In addition, as speckle noise is greatly reduced in the coarsest pyramid level, the contours can avoid trapping in local minima during the evolution. <> stream The DFI method is based on a forward approach making use of a priori information about the position and shape of the B-mode image frames (e.g., masking information) to optimize the reconstruction procedure and to reduce computation times and memory requirements. In this chapter, a new technique is presented to enhance the blurred images obtained from retinal imaging; Fundus Photographs, and Fluorescein Angiograms. Inversion is performed numerically and may include regularization when the projection data is insufficient. Medical ultrasound systems require computation of complex algorithms for real-time digital signal processing. Coded aperture imaging was originally developed in X-ray astronomy. GPU's have recently emerged as a significantly more powerful computing platform, capable of several orders of magnitude faster computations compared to CPU based approaches. Multiangular coded aperture projections are acquired and a stack of 2D images is first decoded separately from each of the projections.
