| machine types | portable |
| machine types | ceiling mounted |
| machine types | digital and flat films |
| restraint | sedation is usually safest |
| other methods restraint | twitch, chain over nose, knock on head, pick up a leg |

| positioning goals | horse standing squarely, weight evenly distributed |
| positioning goals | well- defined joint spaces |
| positioning goals | no motion |
| cassette positioning | stand in safest place |
| cassette positioning | never stand directly behind horse |
| cassette positioning | move slowly, do not startle horse |
| cassette positioning | always use cassette holder, never hold cassette with hands. |
| cassette positioning | always wear lead |
| labeling | appropriate markers visible in film emulsion |
| labeling | correct markers for obliques |
| labeling | lateromedial/ mediolateral views ( marker on cranial aspect of the limb) |
