1. General
1.1 General
L55 Probe is a Linear Array Probe.
The acoustic output of L55 Probe was measured according to the
IEC60601-2-37 standard and the measurement was conducted by
operating with the Hitachi ultrasound diagnostic scanner.
The measured acoustic output is listed in the instruction manual
of the Hitachi ultrasound diagnostic scanner.
L55 Probe is categorized in class IIa according to Directive
93/42/EEC and classified as type BF according to IEC60601-1.
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.

1.4.3 Magnetic Sensor Attachment
Sterilization has not been made to the elasto coupler, the
magnetic sensor attachment and the needle guide bracket
EZU-PA7L2 shipped from the factory.
Prior to use of them, be sure to clean, disinfect and
sterilize them.
A biopsy should be performed only by a well-trained physician.
Use only the authorized needle guide bracket EZU-PA7L2 for
performing a biopsy.
Before performing a biopsy, display the needle echo in sterile
water, and confirm that the needle echo at each angle overlaps
with the correspondent needle guideline. For the confirmation
procedure in detail, refer to the instruction manual of
EZU-PA7L2.
