![]() The limitations of perceptions were emphasized by Minski and Papert (1969). In 1962, Windrow introduced a device called the Adaptive Linear Neuron (ADALINE) by implementing their designs in hardware. In 1958, Frank Rosenblatt’s landmark paper defined the structure of the neural network called the perceptron for the binary classification task. In 1949, a book titled “Organization of Behavior” was the first to describe the process of upgrading synaptic weights which is now referred to as the Hebbian Learning Rule. A neurophysiologist, Warren McCulloch, and a mathematician Walter Pitts developed a primitive neural network based on what has been known as a biological structure in the early 1940s. The study of artificial neural networks and deep learning derives from the ability to create a computer system that simulates the human brain. Deep learning (DL) applications in medical images are visualized in Fig. CNN is an artificial visual neural network structure used for medical image pattern recognition based on convolution operation. When DLA is applied to medical images, Convolutional Neural Networks (CNN) are ideally suited for classification, segmentation, object detection, registration, and other tasks. DLA is generally applicable for detecting an abnormality and classify a specific type of disease. In medical image analysis, unsupervised learning algorithms have also been studied These include Deep Belief Networks (DBNs), Restricted Boltzmann Machines (RBMs), Autoencoders, and Generative Adversarial Networks (GANs). Recurrent Neural Networks (RNNs) and convolutional neural networks are examples of supervised DL algorithms. ĭifferent forms of DLA were borrowed from the field of computer vision and applied to specific medical image analysis. A large number of recent review papers have highlighted the capabilities of advanced DLA in the medical field MRI, Radiology, Cardiology, and Neurology. In general, DL has two properties: (1) multiple processing layers that can learn distinct features of data through multiple levels of abstraction, and (2) unsupervised or supervised learning of feature presentations on each layer. The concept of DL algorithms was introduced from cognitive and information theories. DL is one part of ML, and DL can automatically extract essential features from raw input data. Deep learning (DL) techniques solve the problem of feature selection. The ML techniques include the extraction of features and the selection of suitable features for a specific problem requires a domain expert. ML uses three learning approaches, namely, supervised learning, unsupervised learning, and semi-supervised learning. Machine Learning (ML) is an application of AI that can be able to function without being specifically programmed, that learn from data and make predictions or decisions based on past data. Besides, medical images can often be challenging to analyze and time-consuming process due to the shortage of radiologists.Īrtificial Intelligence (AI) can address these problems. Radiography, endoscopy, Computed Tomography (CT), Mammography Images (MG), Ultrasound images, Magnetic Resonance Imaging (MRI), Magnetic Resonance Angiography (MRA), Nuclear medicine imaging, Positron Emission Tomography (PET) and pathological tests. In the health care system, there has been a dramatic increase in demand for medical image services, e.g. This review guides the researchers to think of appropriate changes in medical image analysis based on DLA. ![]() It provides a systematic review of the articles for classification, detection, and segmentation of medical images based on DLA. Most of the DLA implementations concentrate on the X-ray images, computerized tomography, mammography images, and digital histopathology images. This paper presents the development of artificial neural networks, comprehensive analysis of DLA, which delivers promising medical imaging applications. DLA has been widely used in medical imaging to detect the presence or absence of the disease. Deep Learning Approach (DLA) in medical image analysis emerges as a fast-growing research field. Basicsof the principles and implementations of artificial neural networks and deep learning are essential for understanding medical image analysis in computer vision. Medical imaging plays a significant role in different clinical applications such as medical procedures used for early detection, monitoring, diagnosis, and treatment evaluation of various medical conditions. ![]()
