3) When examining mammograms, radiologists often deal with four to six images at a time. (continued)?
For a reasonable digital representation of a mammogram, a pixel array of 3000 by 4000 is needed and 12 bits of grayscale are used to represent each pixel.
a. How many bits are needed to represent a single mammogram image?
b. How many bits are needed to represent four mammogram images?
c. How long (in seconds) would it take to send four mammogram images from a radiologist's office to a hospital over a T-1 line (1.544 Mbps, i.e. 1.544.000 bps)?

a. 3,000 × 4,000 × 12 = 144,000,000 bits
b. 1,4400,0000 × 4 = 576,000,000 bits
c. 576,000,000 ÷ 1,544,000 = 373 seconds
