A 36 cm ×48 cm chest radiograph is digitized to preserve 6 cycles/mm at 8-bit quantization. Find approximate image size in MB to two decimals, using the binary megabyte convention intended by the source.
Nyquist requires at least twelve pixels per millimetre for six cycles/mm. Image dimensions are 360×12=4320 and 480×12=5760 pixels, totaling 24883200 pixels. Eight bits equal one byte each. Dividing by 2²⁰ gives 23.7305 MiB, written as 23.73 MB in the source. A decimal megabyte convention would instead give 24.88 MB.
