👉 An ultrasonogram is a diagnostic imaging technique used to visualize internal structures in the body, such as bones, muscles, and organs. It uses high-frequency sound waves to create a three-dimensional image of the structure being imaged. The ultrasonic waves are generated by an ultrasound machine that emits sound waves at various frequencies, which can be tuned to detect specific structures or changes in tissue density. Ultrasonograms can be used to diagnose conditions such as bone fractures, heart disease, and cancer, among
