1. Introduction
1.1 Features
S31 probe is a phased array sector scanning type probe.
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.
This probe is categorized in class IIa according to Directive
93/42/EEC.
According to IEC60601-1 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. This system operates under the
principles 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 vibration energy for emitting
pulse-shaped 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.

2. Inspection before Use
Prior to use, the probe must be carefully inspected that it is
appropriate for use. If not, do not use the probe and immediately
contact a service support.
2.1 Inspection for appropriate connection
1) Confirm that the system is correctly operating. Refer to the
instruction manual for the ultrasound diagnostic scanner.
2) Do not attach or connect unauthorized devices nor instruments
on the probe, such as unauthorized biopsy attachments.
2.2 Inspection of material surface
Visually check the surface of the probe head, housing and cable for
any crack, scratch or denaturalization.
