Bone algorithm is used as a principle in which of the following modality?: (A) Spiral CT, (B) Multidetector CT, (C) Dual source CT, (D) HRCT
Answer is D. High resolution CT: It is a scanning protocol in which thin sections (usually 0.625 to 1.25 mm) are acquired and reconstructed using Bone Algorithm, which is a high spatial resolution reconstruction and improves image sharpness and clarity of pulmonary parenchyma.
