Digital images have several benefits, such as faster and inexpensive processing cost, easy storage and communication, immediate quality assessment, multiple copying while preserving quality, swift and economical reproduction, and adaptable manipulation. Digital medical images play a vital role in everyday life. Medical imaging is the process of producing visible images of inner structures of the body for scientific and medical study and treatment as well as a view of the function of interior tissues. This process pursues disorder identification and management. Medical imaging in 2D and 3D includes many techniques and operations such as image gaining, storage, presentation, and communication. The 2D and 3D images can be processed in multiple dimensions. Depending on the requirement of a specific problem, one must identify various features of 2D or 3D images while applying suitable algorithms. These image processing techniques began in the 1960s and were used in such fields as space, clinical purposes, the arts, and television image improvement. In the 1970s, with the development of computer systems, the cost of image processing was reduced and processes became faster. In the 2000s, image processing became quicker, inexpensive, and simpler. In the 2020s, image processing has become a more accurate, more efficient, and self-learning technology. This book highlights the framework of the robust and novel methods for medical image processing techniques in 2D and 3D. The chapters explore existing and emerging image challenges and opportunities in the medical field using various medical image processing techniques. The book discusses real-time applications for artificial intelligence and machine learning in medical image processing. The authors also discuss implementation strategies and future research directions for the design and application requirements of these systems. This book will benefit researchers in the medical image processing field as well as those looking to promote the mutual understanding of researchers within different disciplines that incorporate AI and machine learning. FEATURES Highlights the framework of robust and novel methods for medical image processing techniques Discusses implementation strategies and future research directions for the design and application requirements of medical imaging Examines real-time application needs Explores existing and emerging image challenges and opportunities in the medical field

This textbook introduces the essential concepts of tomography in the field of medical imaging. The medical imaging modalities include x-ray CT (computed tomography), PET (positron emission tomography), SPECT (single photon emission tomography) and MRI. In these modalities, the measurements are not in the image domain and the conversion from the measurements to the images is referred to as the image reconstruction. The work covers various image reconstruction methods, ranging from the classic analytical inversion methods to the optimization-based iterative image reconstruction methods. As machine learning methods have lately exhibited astonishing potentials in various areas including medical imaging the author devotes one chapter to applications of machine learning in image reconstruction. Based on college level in mathematics, physics, and engineering the textbook supports students in understanding the concepts. It is an essential reference for graduate students and engineers with electrical engineering and biomedical background due to its didactical structure and the balanced combination of methodologies and applications,

The purpose of tomography is to reconstruct a volume from its projections. In Computed Tomography (CT), X-rays are transmitted to a patient and attenuated by their tissues: the projections are obtained from the measured attenuation. For Positron Emission Tomography (PET), a radionuclide injected inside a patient emits a positron that generates two gamma photons in opposite directions. The projections correspond to the set of lines of response between each pair of simultaneously detected photons. Tomographic reconstruction for PET or CT amounts to solving an inverse problem. Analytical methods are fast but their efficiency is limited when data are under-sampled or noisy. Iterative methods are efficient for noise and artefacts removal, but the computation time represents a major drawback for practical use. Deep learning based methods have the potential to overcome those limits. The first objective of this thesis is to study the impact of the training loss on medical diagnosis-oriented evaluation metrics. We perform this study on bone microarchitecture CT imaging and show that in this case L1 loss should be used regarding all the considered metrics. Networks trained with perceptual losses show better transcription of structural features, at the cost of a deteriorated resolution. Adversarial losses improve the accuracy of the reconstruction in terms of density distribution. We then focus on Time of Flight (TOF) PET data for intraoperative surgical applications; our aim is to design a reconstruction method to improve the detectability of small tumors in the context of breast cancer. We propose a neural network called PAVENET that simultaneously retrieves the image and the image-dependent point-spread function (PSF) from a poor-quality initial reconstruction. We present in this thesis the proof of concept for PAVENET with experiments on Monte-Carlo simulations reproducing acquisitions from an innovative detector studied in the Radiation Physics Instrumentation Laboratory (RPIL) in Boston.
