Questions and Answers 100% Solved


Matrix size = - ✔✔Matrix size = M x N x k bits

Field of View (FOV) - ✔✔- Overall dimensions of

the matrix.

- In CR and DR the size

of the FOV is

determined by the

size of the detector

pixel size= - ✔✔FOV/matrix

What happens to pixel size as Matrix size increases (FOV stays the same)

- ✔✔As Matrix size gets bigger, pixel size gets smaller (if FOV stays the

same)

Bit Depth - ✔✔- Number of shades of gray each pixel is capable of

displaying

- M x N x k bits

- Each pixel =2k gray levels
