Non-invasive Head Fixture

	Before the procedure, a pair of holders (depicted in blue) should be prepared; a plastic ball can be used for this. The holes on the holders work as anchors when impression material (see below) becomes fixed. To get clear impression of a head, inner size of the holders might be 2cm larger than a head. The animal is lightly anesthetized by Ketamine. Rubber tubings are placed in nose with tapes and a few drops of glue to maintain animal's respiration. Hair is removed to prevent impression material from catching the hair. For the same reason, the animal's torso have to be wrapped by a sheet of paper or cloth; here we use a surgical drape (water-proof). TIPS: Hair-remove cream should be totally rinsed on a skin, or it will cause skin damage.
