Film critique is the evaluation of radiographic images to determine whether they meet diagnostic standards. Students learn to identify errors in exposure, positioning, collimation, motion, contrast, detail, and artifacts. Effective critique skills allow technologists to correct mistakes, improve image quality, and reduce the need for repeat exposures.
To build a strong foundation, begin with Radiographic Principles to understand how exposure factors influence image quality. Review Radiographic Positioning to identify positioning errors. Study PACS and Digital Imaging to understand how digital processing affects the final image.
Summary: Film critique teaches how to evaluate image quality and identify errors. Strengthen your understanding by reviewing radiographic principles, analyzing positioning, and exploring digital processing.
Quantum mottle, grainy appearance, poor detail.
Loss of contrast, saturation, clipped highlights.
Affects density and noise levels.
Affects penetration, contrast, and scatter.
Often due to high kVp or scatter.
Often due to low kVp or insufficient penetration.
Background density from scatter or processing.
Asymmetry of anatomy, misaligned structures.
Distortion, elongation, or foreshortening.
Misalignment with IR or CR.
Cut‑off anatomy or poor centering.
Patient movement causing blur.
Breathing, heartbeat, peristalsis.
Tube or IR movement during exposure.
Increases scatter and reduces contrast.
Missing anatomy or clipped structures.
Cut‑off or misaligned anatomy.
Unwanted densities or shadows.
Grid cutoff, moiré patterns.
Dead pixels, stitching errors, processing issues.
Blur or ghosting.
Incorrect processing due to mis‑identification.
Incorrect EI due to collimation or scatter.
Wrong body part or LUT applied.
Identifies patterns in errors.
Reduces patient dose and improves workflow.
