Machine learning is a branch of AI that focuses on developing algorithms that can learn from data and make predictions or decisions without explicit programming. In medical imaging, machine learning algorithms can be trained on large datasets of labeled medical images to recognize patterns and make accurate diagnoses.

3.2 Deep Learning

Deep learning is a subset of machine learning that uses artificial neural networks with multiple layers to analyze and extract complex features from data. Deep learning has shown remarkable success in medical imag tasks, achieving human-level performance in some cases. Convolutional neural networks (CNNs), a type of deep learning architecture, have been particularly effective in image classification and segmentation tasks.

3.3 Convolutional Neural Networks (CNNs)

CNNs are deep learning models specifically designed for analyzing visual data, such as images. These networks consist of multiple layers of interconnected nodes, which learn to extract relevant features from images through a process of convolution and pooling. CNNs have been widely used in medical imag for tasks such as tumor detection, organ segmentation, and disease classification.

3.4 Image Segmentation

Image segmentation is a crucial task in medical imaging, as it involves identifying and delineating specific structures or regions of interest within an image. AI algorithms, particularly deep learning-based approaches, have demonstrated impressive performance in image segmentation tasks. Accurate segmentation can aid in the diagnosis and treatment planning of various medical conditions.
