For horizontal biopsies (no angulations, 0°) the handling of the NORAS
Mammotome® MR adaptor is equal to the standard NORAS positioning
devices.
For angulated biopsies please note that the center of rotation varies from the
standard NORAS positioning devices. The center is located 68mm (not the usual
22mm) behind the head of the pointer, which is visible in the MR image. In order
to calculate the coordinates you have to subtract 68mm from the position of the
head of the pointers line.
For angulations use, turn the adjustment screw at the front of the fi ducial holder
until you are able to change the angle. Anterior as well as posterior angulations
are possible for 15° and 30°. After the angulations adjustment close the adjustment
screw slowly until the new position of the fi ducial holder is fi xated.

In case of a very anterior lesion position the guide fork (Ethicon) can be set on a
higher position, which enables another 17mm anterior access. Please note that
in this procedure the holster must be held upside down so that tissue samples
will fall downwards.
