Ultrasonic inspection principles

Ultrasound is a technology that uses high-frequency sound waves to examine conditions inside the body. When the ultrasonic waves emitted by the ultrasonic instrument are transmitted through the skin to body organs or tissues, varying degrees of reflection will occur. By analyzing the return signal through the ultrasonic receiver, an image of the detection range can be drawn.

Application

Ultrasound is widely used in diagnosing, guiding medical procedures, and treating, and is often used to

• Prenatal care during pregnancy: Ultrasound can be used to monitor fetal development, confirm fetal gender, and confirm multiple pregnancies
• Diagnosis of diseases: Ultrasound can scan the thyroid, heart, liver, gallbladder, bladder, kidneys, blood vessels, reproductive organs and other body parts to assist in the diagnosis and treatment of various types of diseases.
• Guided treatment: Ultrasound can also guide needle biopsy or guide injection treatment.

Safety instructions

Ultrasound is a very safe diagnostic imaging method. A small number of patients may feel slight discomfort when medical staff place the probe on their body.

Check process

Preparation before inspection
