Biological imaging is a technique used to visualize the structures and functions of living organisms at various scales, from cells to entire organisms. This field employs various methods, such as MRI (Magnetic Resonance Imaging), CT scans (Computed Tomography), and fluorescence microscopy, to capture detailed images. These images help scientists and doctors understand biological processes, diagnose diseases, and monitor treatment effects. One of the key benefits of biological imaging is its ability to provide real-time insights into living systems without causing harm. For example, PET scans (Positron Emission Tomography) can track metabolic activity in tissues, aiding in cancer detection. Overall, biological imaging plays a crucial role in advancing medical research and improving patient care.
