Carpus / Forepaw - Lateral carpus (Positioning, centring, collimation)
Positioning: Lateral recumbency, forelimb drawn cranially
Centring: Carpal joint
Collimation: Distal radius/ulna, end of digits, lateral skin edges
Femur - Lateral (Positioning, centring and collimation)
Positioning: Dorsal recumbency but turned slightly so limb of interest falls towards table, extend other limb away, foam wedge under hock so femur is parallel to cassette
Centring: Midway along femur between stifle and greater trochanter
Collimation: Hip, stifle joint and skin edges
Femur - Craniocaudal (Positioning, centring and collimation)
Positioning: Dorsal recumbency in trough, extend limb of interest and other limb away

Positioning: Lateral recumbency
Centring: Midway between hock and stifle
Collimation: Stifle and hock joints, cranial and caudal skin edges
Tarsus (Hock) - Lateral and Craniocaudal (P,C,C)
Positioning Lateral: Lateral recumbency, limb of interest closest to plate, foam wedge under stifle to correct rotation
Positioning Craniocaudal: Dorsal recumbency with trough, limb of interest closest to plate
Centring: Over the tarsus
Collimation: Distal tibia/fibula, meta-tarsals, cranial and caudal skin edges
