General description
Vscan is a battery operated pocket-sized general purpose
ultrasound imaging system.
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 probe. The mechanical
ultrasound waves spread through the body, producing an echo
where density changes occur. The echoes return to the probe
where they are converted back into electrical signals.
These echo signals are 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.
A probe is an accurate, solid-state device, 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.
Safety
Read and understand all instructions in the User's Manual
before attempting to use the ultrasound unit. Keep the manual
with the equipment at all time. Periodically review the
procedures for operation and safety precautions.
All information in Chapter ‘Safety’ on page 7-1 should be
read and understood before operating the ultrasound unit.
