Table 1.
Technique settings and dosimetry for task-specific protocols in the thoracic and lumbar spine. “Bone Protocol” refers to a lower dose technique sufficient for high-contrast bone visualization. “Soft-Tissue Protocol” refers to a higher dose technique sufficient for soft-tissue visualization.
