When neither the coronal nor sagittal plane are placed perpendicular to the plane of the image receptor, what position is described?

Axial

Oblique

Oblique positioning is used when the body part is rotated between the frontal (coronal) and lateral orientations so that neither plane is perpendicular to the image receptor. In this scenario, you’re not viewing the anatomy strictly from the front/back or side, but at an angle between them. That off-angle alignment is what defines an oblique projection. The other terms describe different ideas: axial refers to a projection along the axis of the part, and AP/PA describe the direction the beam travels relative to the body surface, not the degree of rotation.
