IV. DATASETS USED FOR TRAINING THE AI MODEL

Machine learning algorithms in radiology are trained and validated using a variety of medical imaging datasets. For tasks like picture classification, object detection, segmentation, and disease diagnosis, these datasets are essential for creating and testing AI models. In the study and development of AI radiology, the following datasets are frequently used are The Cancer Imaging Archive (TCIA) which is a comprehensive repository for cancer imaging data, comprising datasets from several imaging modalities like CT, MRI, and PET scans. It has data from a variety of cancer types and National Lung Screening Trial (NLST) is a crucial tool for the early diagnosis and study of lung cancer since it collects CT scans from people who are at high risk for the disease. The Digital Database for Screening Mammography (DDSM) is a dataset made up of mammograms and the ground truth labels that go with them. It is primarily used to identify breast cancer. ImageNet is a sizable dataset used for convolutional neural networks (CNNs) training, despite not being specifically related to radiology. On ImageNet, researchers may train CNNs in advance and then fine-tune them for radiological tasks. OpenI is a collection of open-access chest X-rays and the radiology reports that go with them is known as OpenI. It is frequently employed in radiology research pertaining to text-based image retrieval and NLP. ChestX-ray14 is a dataset, which contains more than 100,000 chest X-ray images labeled for a variety of thoracic disorders, is valuable for creating AI models for analysing chest X-rays. Lung Image Database Consortium and Image Database Resource Initiative (LICD-IDRI) is a useful tool for identifying and characterizing lung nodules is LIDC-IDRI, which has lung CT scans annotated for nodules. Brain MRI Datasets contains a number of brain MRI scan datasets are available for activities including detecting brain tumours, segmenting them, and classifying diseases. The Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset is one example. Prostate MRI Datasets is a ProstateX dataset is a famous example of a dataset of prostate MRI images used for the detection and diagnosis of prostate cancer. Retinal imaging datasets are one example of a dataset with retinal images is the Kaggle Diabetic Retinopathy Detection dataset, which is used to identify diabetic retinopathy. Datasets of cardiac pictures, such as echocardiograms and cardiac MRI scans, are utilized for activities linked to the diagnosis and evaluation of heart illness. Pediatric Imaging Datasets are the NIH Pediatric MRI Data Repository is one of the datasets utilized in pediatric radiology research that includes medical pictures of children. Mammography Images are the dataset help with breast cancer detection.

MRI Brain Images is used to understand issues like Alzheimer's disease. CT Scans are detailed images used for finding things like lung nodules or problems in the liver and kidneys. Histopathology Images are the Pictures of tissue samples help in cancer detection. For the purpose of advancing radiology AI research, these datasets are frequently annotated and maintained. It is critical to remember that while working with medical imaging data, researchers must adhere to data usage and privacy restrictions and that access to some of these datasets may be restricted. In addition, developing fresh, customized datasets can be required for certain research aims and therapeutic applications.

V. ALGORITHM USED TO READ THE DATASET TO TRAIN THE AI MODEL

Convolutional Neural Networks (CNNs) go through a number of processes to read and process datasets for training AI models, notably for image-related applications. The dataset must first be loaded into memory. This entails accessing the dataset files and getting them ready for input using programming libraries and tools. For picture datasets, this can entail reading image files along with any labels or annotations they may have. To make raw data appropriate for training, preparation is frequently                                  necessary. Common preprocessing are resizing, normalization, OneHot Encoding. Images can be downsized to a standard resolution to maintain uniform dimensions. In order to stabilize training and boost convergence, pixel values are scaled to have a mean of 0 and a standard deviation of 1. Labels are frequently one-hot encoded when classification is the task, converting categorical labels into a binary vector format. Convolutional layers are the main constituents of CNNs. These layers run the incoming data through a series of trainable filters (kernels). Slided over the input, these filters compute dot products and generate feature maps that identify regional patterns or characteristics. Pooling layers are frequently used after convolutional layers to decrease computational complexity and spatial dimensions while preserving crucial features. Max-pooling and average-pooling are two common pooling techniques. Lattening is a one-dimensional vector is created using the feature maps that the convolutional and pooling layers have produced. The information is now ready to be entered into a fully linked neural network. Layers that are fully connected link every neuron in one layer to every neuron in the one above. To make final predictions, fully connected layers are often used toward the conclusion of the CNN design. They may have several submerged layers. For classification tasks, the output layer typically has the same number of neurons as the classes in the dataset. It might just have one neuron for regression tasks. To add non-linearity to the network, activation functions like ReLU (Rectified Linear Unit), Sigmoid, or Softmax are applied at each layer. In Loss Function CNNs measure the error between the predicted outputs and the ground truth labels using a loss function (for example, cross-entropy for classification). Optimization is to update the weights of the network and minimize the loss function, gradient descent optimization methods are utilized (e.g., Adam, SGD). During training, preprocessed input data are fed into the CNN in batches, and backpropagation is used to update the weights. The model is trained for a predetermined number of epochs or until it reaches an acceptable performance level. Validation is to keep track of the model's generalizability and prevent overfitting, its performance is periodically assessed on a different validation dataset. Testing is to evaluate the model's performance in the real world, a test dataset is used after training is finished and the model has demonstrated success on the validation set. In deployment the learned CNN model may be used to make predictions on fresh, unforeseen data following successful training and testing.

VI. BEFORE AND AFTER THE AI IN RADIOLOGY
