👉 A micrograph is a small, high-definition image that captures only a fraction of an object's total surface area. It is often used in medical imaging to show the structure and function of tissues or organs in a patient's body. Micrographs can be created using various techniques such as electron microscopy (EM), scanning tunneling microscope (STM), or confocal microscopy, among others. They are particularly useful for diagnosing diseases by observing small changes in tissue structures that might not be visible with the naked
