1. Introduction
1.1.
Features
The probe of Model EUP-F531 is Convex Array electronic scanning type.
The acoustic output of this probe when connected to ultrasound scanner
was measured according to the IEC60601-2-37 standard. The table of
measured acoustic output data is contained in the operation manual of
each ultrasound scanner.
according to Directive 93/42/EEC. According to IEC 60601-1 the probe
is classified as type BF.
1.2.
Principles of operation
This probe and the ultrasound diagnostic scanner enable image diagnosis
using ultrasonic waves.
described below.
1) When an electric pulse signal is applied from the transmitter to the
transducer of the probe, the transducer converts electric signals
into
mechanical
ultrasonic waves into the body part, liquid or other medium
contacting the transducer.
2) The emitted ultrasonic waves are reflected by boundaries with
different acoustic characteristics (acoustic impedance) within the
body.
3) The transducer is also used to receive reflected ultrasonic waves.
The transducer vibrates mechanically due to the received ultrasonic
waves and converts mechanical vibrations into electric energy.
Electric signals are converted to shades of brightness by brightness
modulation to obtain an image.
1.3.
