Final answer:
An echogram or sonograph, a graphic representation of echo-sounding data, is used in medical imaging for visualizing body structures, in oceanography for studying underwater features, and in the fishing industry for identifying schools of fish.
Step-by-step explanation:
An echogram or sonograph is a graphic representation of echo-sounding data. It is commonly used in the following three areas:
- Medical Imaging: Sonography, also known as ultrasound imaging, is a widely used diagnostic tool in medicine. It helps visualize subcutaneous body structures such as tendons, muscles, joints, vessels and internal organs.
- Oceanography: Echograms are used to study the underwater features of oceans and seas. The data collected can help identify underwater mountains, trenches, and other geological formations.
- Fishing Industry: Fishing vessels often use echo-soundings or sonographs to identify schools of fish. This helps in sustainable fishing practices by avoiding overfishing in a particular area.
