•
The table motion is force limited to 200 N as a protective measure to reduce the risk of
entrapment and pinching.
•
The gantry employs covers to protect the patient against rotating parts, and provides cover
interlocks to inhibit gantry rotation when the covers are open.
•
Sensors are located beneath the table to detect collision and stop motion.
Illustration 16: Table Collision Sensor Locations
Sensors are located underneath the front and back of the table. These sensors indicate where
there is potential for collisions with items such as wheel chairs or stretchers. When a sensor is
touched, table and gantry movement stops immediately. In this event, clear the area and
continue positioning the table.
There is a mark on the cradle for maximum scannable range.
CAUTION
If the table is lowered with anything in the red X area, as indicated in the figure
below, the table could be damaged along with the equipment or object under the
table.
