The design of Model 900M-B MRI Head Holder Assembly allows easy access and removal from the stereotaxic base for insertion into MRI device. Animals head position remains constant. The removable MRI head holder was designed to fit into a MRI device 12 cm diameter (or larger).

Model 920M MRI Rat Adaptor features include a nose and tooth bar assembly offering various stereotaxic adjustments

Dorsal/Ventral adjustment – 20 mm
Dorsal – 10 mm above ear bar zero
Ventral – 10 mm below ear bar zero
Adaptor Plate A/P adjustment – 46 mm

Ear Bars – Model 955M MRI Non-Rupture 45° Tip Rat Ear Bars with fillable fluid marker tip included (6.3 mm square with 20 mm of calibration).

Another unique feature that this instrument offers are ear bars which can be filled with a reference fluid marker, such as Vitamin E or Mineral Oil. Ear bars have removable extensions. Once the animal is properly secured within the head holder, the back of the ear bar can be unscrewed and removed, this will assist when loading MRI head holder into small diameter MRI devices.
