Sonography 101

Ultrasound Examination

• High-frequency sound waves are used to assess organs, tissues, and blood flow inside the body in a medical investigation called ultrasound.
• A sonographer uses a probe, also known as a transducer, during an ultrasound examination.
• The probe emits high-frequency sound waves during an ultrasound examination.
• The ultrasound machine determines the distance and speed of the sound waves by recording echoes from the sound waves.
• Ultrasound exams provide doctors with information about a patient's internal organs, tissues, and blood flow, helping diagnose and monitor medical conditions.
• The instrument used by a sonographer to assess the body is the probe, which emits high-frequency sound waves.
• The ultrasound machine determines the location, size, shape, and consistency of internal organs and tissues by recording echoes from the sound waves.
• The main purpose of an ultrasound exam is to produce images of internal organs and tissues to help diagnose and monitor medical conditions.
• Diagnostic ultrasound, as defined by Sonography Canada, is a non-invasive medical imaging modality that uses high-frequency sound waves to produce images of the internal organs and tissues.
• When the probe emits high-frequency sound waves during an ultrasound examination, the sound waves bounce off internal organs and tissues, and the echoes are recorded by the ultrasound machine to produce images.
