Flat Detector Contact
The hand or wrist must lie flat against the detector to avoid distortion. Gaps create magnification and blur. Proper contact improves spatial resolution. Flat positioning is essential for accurate imaging.
Oblique Angles
Standard obliques require consistent angles to visualize joint spaces. Incorrect angles can obscure fractures or dislocations. Using positioning blocks improves accuracy. Consistent obliques enhance diagnostic reliability.
Finger Separation
Separating fingers prevents overlap of phalanges. Overlapping structures reduce clarity and complicate interpretation. Simple adjustments improve visualization. Finger separation is a key positioning step.
Marker Placement
Accurate marker placement prevents confusion during interpretation. Markers should be placed outside the anatomy but within the field. Proper labeling supports clear documentation. Good marker habits reduce errors.
