Procedural modifications simulated
| Simulation | Initial projection | Rotation |
|---|---|---|
| Rotation from initial PA projection | PA | LAO, RAO, CRA, CAU |
| Rotation from initial LAO/RAO projection | 30° LAO | LAO, RAO, CRA, CAU |
| 60° LAO | RAO, CRA, CAU | |
| 30° RAO | LAO, RAO, CRA, CAU | |
| Rotation from initial compound projection | 60° LAO+30° CRA* | RAO, CRA, CAU |
| 30° RAO+30° CRA† | LAO, RAO, CRA, CAU |
*Often used to visualise left main stem and distal LAD coronary arteries.18
†Often used to visualise the middle segment of the LAD.18
CAU, caudal; CRA, cranial; LAD, left anterior descending; LAO, left anterior oblique; PA, posteroanterior; RAO, right anterior oblique.
