Imaging systems are technologies used to create visual representations or pictures of objects, tissues, or structures within the body. These systems are used in various fields such as medical imaging, remote sensing, surveillance, and industrial inspection. They can utilize different imaging modalities such as X-ray, MRI, ultrasound, CT scans, and optical imaging to capture images and provide valuable information for diagnosis, monitoring, and analysis. Imaging systems play a crucial role in improving our understanding of the world around us and are constantly evolving with advancements in technology.
