PREPARING THE EQUIPMENT
Note:
Note:
Note:
Set the image receptor, focal distance, field size, and compression paddle for the required
view.
For standard exposures, use 18x24 cm or 24x30 cm cassettes and a compression paddle
suitable to the format selected. Use of the Bucky is suggested for contact views.
For best results in AOP, it is recommended to match the format of the compression
paddle with the format of the bucky when in contact mode, i.e. use the 18 x 24
compression paddle with the 18 x 24 bucky/cassette holder, and use the 24 x 30 paddle
with the 24 x 30 bucky.
* The Senographe DMR 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).
* 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.
* Trying to make an exposure without a cassette in the bucky/cassette holder or
without having changed the cassette between two exposures will result in a
beep sound and a message will be displayed on the column and the control
console and the exposure will be inhibited.
* When inserting a cassette in the bucky, make sure that it is inserted all the way
in and held firmly between the 2 stoppers.
For additional exposures (selective exposure and/or magnification), the SID and
source-to-object distance can be modified.
No specific tube warm–up procedure is needed at power on.
Different field sizes and compression paddles can be used.
Use of the Bucky is not recommended in magnification.
RAD PARAMETERS
The rad parameter selection depends on the focal track/filter configuration.
