CHAPTER 1 – INTRODUCTION
The SENOGRAPHE 800T is an x-ray system used primarily for mammography
examinations in the standing or sitting position. Breast localizations by two dimensional
localization is an additional function by using the optional cross hair device. If required, the
system can provide as well, high image quality radiography of specimens and of the hand and
foot.
The major features of the SENOGRAPHE 800T are: the Molybdenum x-ray tube – Rhodium
and Molybdenum filters – an entirely automatic exposure mode – a digital readout and display
of the arm angulation, of the compressed breast thickness and of the breast compression force
– a manual compression fine tuning – and its new ergonomic design.
The SENOGRAPHE 800T is equipped with the well proven GE Molybdenum X–Ray tube
that provides high quality radiology images. The Rhodium filter allows better penetration of
glandular tissue and dose reduction for dense breasts.
Standard or magnification examinations can be performed. Focal spot sizes are: 0.3 for
contact exams and 0.1 for magnification exams.
Three modes of exposure are available:
The Automatic Exposure Control (AEC) Mode controls density (mAs) and provides
exposures of constant optical density.
The Automatic Optimization Parameters (AOP) Mode controls radiation. For a given
priority (dose reduction, contrast quality or compromise), the AOP Mode selects the filter,
and kV. It includes the AEC mode, and provides an automatic selection of the radiological
parameters (filter, kV, and mAs).
In addition, a totally manual exposure mode (MAN) can be used in special cases. For example
when the breast does not cover the entire photocell, when examining breasts with silicone
implants, or when making examinations of extremities (hands, ...).
The new ergonomic design, coupled with features like digital readouts for gantry angle –
breast compressed thickness – breast compression force, and manual compression fine tune
ensures speed, accurate positioning and ease of use, with examination comfort for the patient.
