4.4 Vascular Examining (Optional)

WARNING
The Doppler is not intended for ophthalmic use. Do not use it for examining ophthalmic
vessels, or any other procedures which may cause the ultrasound beam to pass through
the eye.
4 MHz, 5 MHz or 8 MHz vascular probes are to be connected to the Doppler to perform vascular
examination.
Choose the appropriate probe as required. The probe with low frequency has a deeper penetration
depth, while the probe with high frequency has better resolution and wider detecting range. The 4
MHz vascular probe is optimized for examining blood vessels; the 5 MHz vascular probe is
optimized for examining deeper vessels, and the 8 MHz vascular probe is optimized for
examining surface vessels.
Apply a liberal amount of gel on the site to be examined. Place the probe at a 45º angle on the skin
over the vessel to be examined. Adjust the position of the probe to obtain the loudest blood flow
sound. Refer to figure 4-1 for the probe sites:
