Principles of Operation
Medical ultrasound images are created by computer and digital
memory from the transmission and reception of mechanical
high-frequency waves applied through a transducer. The
mechanical ultrasound waves spread through the body,
producing an echo where density changes occur. For example,
in the case of human tissue, an echo is created where a signal
passes from an adipose tissue (fat) region to a muscular tissue
region. The echoes return to the transducer where they are
converted back into electrical signals.
These echo signals are highly amplified and processed by
several analog and digital circuits having filters with many
frequency and time response options, transforming the
high-frequency electrical signals into a series of digital image
signals which are stored in memory. Once in memory, the image
can be displayed in real-time on the image monitor. All signal
transmission, reception and processing characteristics are
controlled by the main computer. By selection from the system
control panel, the user can alter the characteristics and features
of the system, allowing a wide range of uses, from obstetrics to
peripheral vascular examinations.
Transducers are accurate, solid-state devices, providing multiple
image formats. The digital design and use of solid-state
components provides highly stable and consistent imaging
performance with minimal required maintenance. Sophisticated
design with computer control offers a system with extensive
features and functions which is user-friendly and easy to use.
