The oblique view of the hand is an X‑ray projection with the hand rotated about 45° so the dorsal surface is angled to the image receptor. The central ray is perpendicular to the third metacarpal. This view reduces bone overlap and better demonstrates metacarpals, phalanges, and joint spaces, aiding detection of fractures, dislocations, and small cortical defects not clear on PA or lateral views.

An oblique view in X‑ray is a radiographic projection taken with the body or X‑ray beam rotated at an angle (commonly about 45°) between the frontal (AP/PA) and lateral planes. This angled perspective separates overlapping structures, improves visualization of bones, joints, and soft‑tissue detail, and helps detect fractures, alignment issues, or lesions that may be hidden on standard frontal or lateral films.

A lateral X‑ray is taken at a true side (90°) angle, producing a profile image that shows depth, anterior–posterior relationships, and alignment. An oblique view is taken with the body rotated or the beam angled between AP/PA and lateral, revealing structures hidden on standard views and better demonstrating fracture lines, joint surfaces, or small bony detail by changing the overlap of anatomy.

For a PA oblique hand, place the forearm on the table with the palm flat on the image receptor, then rotate the hand laterally about 45° so the fingers lie obliquely and parallel to the receptor. Separate the fingers slightly and extend them, support the elevated ulnar side with a sponge to maintain the 45° obliquity, and center the central ray to the third MCP joint.

An oblique view is an angled radiographic projection taken with the patient or X‑ray beam rotated between frontal and lateral planes to visualize structures hidden on standard AP/PA or lateral images. It separates overlapping anatomy, clarifies fractures, joint spaces and foreign bodies, and improves assessment of spine, ribs, and extremities. Obtained by rotating the patient or angling the beam to achieve the desired obliquity.

An oblique ray is a light ray that strikes or travels through an optical surface at an angle to the system’s principal (optical) axis rather than perpendicularly. Because it is off-axis, it focuses differently than axial rays, contributing to astigmatism and oblique aberrations. Oblique rays are important in optics and clinical eye exams for understanding image formation, field of view, and peripheral distortion.
