The 1st generation (1G) CT scanner uses a point X-ray source and a detector. The source detector assembly can move linearly at a speed of 0.5 m.s⁻¹ and that it takes 0.5 s for source-detector assembly to rotate one angular increment, regardless of the angle.
This scanner is expected to collect 360 projections over 180° of span. The field of view used for data collection has a diameter of 0.5 m. The scan time required is _______ s.
