PHANTOM RESEARCH SET, MAMMOGRAPHY*
Satisfies the full range of size, glandularity and thickness combinations
encountered in clinical mammography.
Enable evaluation of image quality under varying degrees of thickness
and glandularity.
Provides the most accurate reliable test for radiation dose.
Ensures consistent production of diagnostically useful
images.
The Mammography Phantom Research Set includes tissue equivalent phantoms 4.5 and
6 cm
thick. Each phantom contains identical embedded details. The glandular content
of each phantom is 50%, 30%, and 20% respectively. Also included are phototimer
compensation plates enabling a range of thickness from .5 cm to 7 cm with
glandular content of 30%, 50% and 70%. One compensation plate contains embedded
details for evaluation of image quality. A 30x power hand held microscope and
heavy duty foam lined carrying case are included.
Weight of set: 21.4 lbs (10 kg)
The phantoms are composed of resin materials that mimic the photon attenuation
coefficients of a range of
breast tissues. Average elemental composition of the human breast being mimicked
is based on the individual elemental composition of adipose and glandular tissue
reported by Hammerstein.
Attenuation coefficients are calculated by using the "mixture rule" and the
Photon Mass Attenuation and Energy Absorption Coefficient Table of J. H.
Hubbell.
*The methodology and design of these phantoms were developed by Dr.
Panos Fatouros and associates at the Medical College of Virginia.
