Internationale sur la Protection Radiologique et les normes nationales en vigueur.
WARNING
X–RAY EQUIPMENT IS DANGEROUS TO BOTH PATIENT AND OPERATOR
UNLESS MEASURES OF PROTECTION ARE STRICTLY OBSERVED
Though this equipment is built to the highest standards of electrical and mechanical safety, the useful x–ray beam becomes a source of
danger in the hands of the unauthorized or unqualified operator. Excessive exposure to x–radiation causes damage to human tissue.
Therefore,adequateprecautionsmustbetakentopreventunauthorizedorunqualifiedpersonsfromoperatingthisequipmentorexposing
themselves or others to its radiation.
Beforeoperation,personsqualifiedandauthorizedtooperatethisequipmentshouldbefamiliarwiththeRecommendationsoftheInterna-
tional Commission on Radiological Protection, contained in Annals Number 26 of the ICRP, and with applicable national standards.

ACHTUNG
RÖNTGENAPPARATE SIND EINE GEFAHR FÜR PATIENTEN SOWIE BEDIENUNGSPERSONAL,
WENN DIE GELTENDEN SICHERHEITSVORKEHRUNGEN NICHT GENAU BEACHTET WERDEN
Dieser Apparat entspricht in seiner Bauweise strengsten elektrischen und mechanischen Sichereitsnormen, doch in den Händen unbe-
fugter oder unqualifizierter Personen wird er zu einer Gefahrenquelle. Übermäßige Röntgenbestrahlung ist für den menschlichen Orga-
nismus schädlich.
Deswegen sind hinreichende Vorsichtsmaßnahmen erforderlich, um zu verhindern, daßunbefugte oder unqualifizierte Personen solche
Geräte bedienen oder sich selbst und andere Personen deren Bestrahlung aussetzen können.
VorInbetriebnahme diesesApparats solltesich dasqualifizierte undbefugte Bedienungspersonalmit dengeltenden Kriterienfür denge-
fahrlosenStrahleneinsatzdurchsorgfältigesStudiumdesHeftsNr.26derInternationalenKommissionfürStrahlenschutz(ICRP)vertraut

REGULATORY REQUIREMENTS
Note: This equipment generates, uses, and can radiate radio frequency energy. The equipment
may cause radio frequency interference to other medical and non-medical devices and
radio communications. To provide reasonable protection against such interference, this
product complies with emission limits for Group 1 Class A Medical Devices as stated in
EN 60601–1–2.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment is found to cause interference (which may be determined by switching the
equipment on andoff), the user (or qualified service personnel) should attempt to correct the
problem using one or more of the following measures:
Reorientate or relocate the affected device(s).
Increase the separating space between the equipment and the affected device.
Power the equipment from a source different from that of the affected device.
Consult the point of purchase or the service representative for further suggestions.
The manufacturer is not responsible for any interference caused either by the use of
interconnect cables other than those recommended or by unauthorized changes or
modifications to this equipment. Unauthorized changes or modifications could void the
user’s authority to operate the equipment.
To comply with the regulations applicable to an electromagnetic interface for a Group 1
Class A Medical Device, all interconnect cables to peripheral devices must be shielded and
properly grounded. Use of cables not properly shielded and grounded may result in the
equipment causing radio frequency interference in violation of the European Union
Medical Device directive and FCC regulations.

CHAPTER 1 – INTRODUCTION
SECTION 1
PRESENTATION
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
systemcan provideaswell,high image qualityradiographyof specimens andofthehand and
foot.
The major features ofthe SENOGRAPHE 800T are: the Molybdenum x-ray tube– Rhodium
andMolybdenumfilters–anentirelyautomaticexposuremode–adigitalreadoutanddisplay
ofthearmangulation,ofthe compressed breast thicknessand of thebreast compression force
– a manual compression fine tuning – and its new ergonomic design.
Molybdenum x-ray tube
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:
AEC Mode
The Automatic Exposure Control (AEC) Mode controls density (mAs) and provides
exposures of constant optical density.
AOP Mode
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).
MAN Mode
Inaddition,atotallymanualexposuremode(MAN)canbeusedinspecialcases.Forexample
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
ensuresspeed,accuratepositioningandeaseofuse,withexamination comfort for thepatient.

SECTION 2
DESCRIPTION
2–1 Senographe 800T
See Illustration 1–1.
The SENOGRAPHE 800T is composed of the following components:
1. Column,
2. Readout for arm angulation, breast compressed thickness and compression force,
3. Emergency Stop push–button,
4. Control console,
5. Examination arm,
6. X–Ray protective shield,
7. Rotation shaft
8. Red light for cassette detection & exposure inhibit.
Note:
The Senographe 800T is equipped with an exposure interlock feature which prevents an
exposure from being made if there is no cassette in the Bucky/cassette holder, or if the
cassette from the previous exposure has not been changed. However, it is possible for
special purposes such as physicist testing for example to disable this interlock (see
chapter 3 for a detailed explanation).
Trying to make an exposure without a cassette in the Bucky/Cassette–holder or
without having changed the cassette between two exposures will make the red light
(8) come ON. The exposure will be inhibited.
It is not recommended to remove the exposed cassette from the Bucky/Cassette
holder by pushing it out with another cassette. This would prevent the exposure
interlock feature from functioning correctly.
When inserting a cassette in the Bucky, make sure that it is inserted all the way in and
firmly held between the two stoppers.
Examination Arm
Thisarmisconnectedtothe Column by arotating shaft. TheExamination Arm canbe rotated
from +180°to –160°about this shaft.
Rotation Shaft
This couples the examination arm to the Column. The angle of the arm can be read on the
digital display located at the bottom of the column.
Column
It consist mainly of a drive mechanism to hold and elevate the Examination arm. A readout,
located at the bottom of the column indicates:
Examination arm angulation (in degrees – °),
Compressed breast thickness (in millimeters – mm),
Compression force (in deca Newtons – daN).
Emergency Stop
Two Emergency Stop push–buttons are located one on either side of the rotating shaft.
Note: The CE marking label is located on the bottom left hand side of the power supply cabinet
