3 General Information
3.1 Device Description
The GAMMA FINDER® III is a device used for the pre- and in-
tra-surgical detection of substances labeled radioactively
(gamma emitter). It is exceptionally user-friendly due to its
unique concept as a battery-powered, autonomous, hand-
held device.
The GAMMA FINDER® III displays the detected gamma radi-
ation by means of an acoustic signal and, synchronously,
with a numerical value in cps (counts per second) on the dis-
play, which is proportional to the activity level.
3.2 Essential Performance
The device measures gamma radioactivity in a certain en-
ergy range. Main application is the measurement of Tc-99m
and the dual isotope mode which measures I-125 and
Tc-99m simultaneously.
3.3 Intended Use and Contraindication
3.3.1 Intended Use
The GAMMA FINDER® III is intended for the detection of
gamma radiation in the energy range from 20 keV to 512 keV.
The GAMMA FINDER® III is indicated for the extra- and intra-
operative detection of radioactively labelled substances
mainly in the fields breast cancer and malignant melanoma.
3.3.2 Contraindication
Dosimetric applications, detection of radiation other than
gamma, and detection of radiopharmaceuticals with radi-
ation energies outside the above listed energy range are
contraindicated.
