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
This arm is connected to the Column by a rotating shaft. The Examination Arm can be 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
