Parts of an Ultrasonography Machine

An ultrasonography machine, sometimes referred to as an ultrasound machine, is a non-invasive tool use by medical professionals such as doctors, ultrasound technicians, and radiology technologists. Different types of ultrasonography machines are useful for examining the condition of the uterus and fetus in pregnant women, for breast examinations, and for examining internal organs, such as the heart or liver. Although ultrasonography machines may be configured differently depending on the specific tasks they are used for, all ultrasonography machines have the same basic parts.

Central Processing Unit

• All ultrasonography machines have a central processing unit (CPU). The CPU is the brain of the machine and operates much like a home computer. The CPU provides electrical current to the other components of the machine. It regulates, amplifies, and manages the necessary electrical power. The CPU houses the microprocessor and the memory storage devices.

Transducer

• The transducer is the part of the machine that projects ultrasound waves into the body and then retrieves the echo that results when the waves bounce off hard tissue. The transducer is typically connected to the CPU by a flexible coaxial cable, which allows the ultrasound technician to position the transducer at the most advantageous location to get the best image possible.

Display

• Most ultrasonography machines have at least two types of displays, including a video monitor and a printer. The video monitor display allows the medical professional to view live images that are produced by the transducer. The printer allows a still image to be printed. Some ultrasonography machines also have video recording capabilities. This feature is popular with expectant parents who may wish to have a recording of their child while it's still in utero.

Control Panel

• The control panel connects to the CPU with an electronic cable. The control panel allows the ultrasound technician to make any necessary adjustments to the transducers. It may also permit the technician to input and record specific data during the examination.
