Slide 2: The Ultrasound Machine
A basic ultrasound machine has the following parts:
Transducer probe - probe that sends and receives the sound waves
Central processing unit (CPU) - computer that does all of the calculations and contains the electrical power supplies for itself and the transducer probe
Transducer pulse controls - changes the amplitude, frequency and duration of the pulses emitted from the transducer probe
Display - displays the image from the ultrasound data processed by the CPU
Keyboard/cursor - inputs data and takes measurements from the display
Disk storage device (hard, floppy, CD) - stores the acquired images
Printer - prints the image from the displayed data
Slide 3: The basic functional components of an ultrasound imaging system are shown below. THE ULTRASOUND IMAGING SYSTEM
Slide 4: Modern ultrasound systems use digital computer electronics to control most of the functions in the imaging process.
We will now consider some of these functions in more detail and how they contribute to image formation.
