Octostop Compensating Filters are made of silicone rubber. Their absorption is ideal at twice that of muscle, which permits placing them on only one side of the patient. They are light to carry, easy to handle, readily identifiable and not cumbersome. They are positioned with precision close to the patient. If dropped, they do not break or harm anyone. In the vertical position, they adhere with very little pressure (wash with water if they slip). If too sticky, interpose tissue paper. They resist alcohol and heat and are waterproof. Autoclave is recommended for sterilization; alcohol or Zephiran for disinfection.
Finger and toes are much thinner than the wrist and back of the foot. It would be a miracle to find a technique suitable to such variations in thickness. These are precisely the marvels that the GENTLE SLOPE allows. Cassette and filter become inseparable.
ForHands and Wrists:
On the A.P. view, filter only the ringers, since there is little difference in thickness from the hand
For all other views, superimpose up to the metacarpals
Place the toes near the thick end of the filter, for all views
Interposed before the rays, a filter reduces radiation to the patient
Pressure (with a small wood board) often straightens out the toes
