The Cobia Vertical Holder is designed for attaching the Cobia to vertical surfaces like a wall bucky, or Cone Beam X-ray units. The holder comes with an adjustable strap with a suction cup for safe mounting.
For X-ray focal spot measurements, to assure that the X-ray tube focal spot size is within acceptable limits. The Slit Camera can be rotated 90 degrees in the Slit Camera holder.
The Visi-X is optimized for light field/X-ray field alignment measurements. Simply darken the X-ray room and place your Visi-X under the X-ray tube. Adjust the light field and make your exposure. The radiation field will immediately be visualized by the glow of the special phosphor compound. It can also be used for checking the centering of the bucky tray.
