1. Introduction
1.1 General
The model EUP-LV74 is a linear array electronic scanning type
probe. The probe is capable of acquiring Real-time 3D image by
mechanical drive of the acoustic elements.
The acoustic output was measured with operating the Hitachi
Ultrasound diagnostic scanner according to the IEC 60601-2-37
standard. The measured acoustic output is listed in the
instruction manual of the Hitachi ultrasound scanner.
The probe is categorized in class IIa according to Directive
93/42/EEC and classified as type BF according to IEC 60601-1.
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.
1.3 Intended Use
The EUP-LV74 is designed for observation and diagnosis, mainly
of the following regions.
The EUP-LV74 is operational with only the HITACHI ultrasound
scanner.
Mammary gland
Thyroid
Superficial organs
