2. Calculate the spatial resolution, or pixel size, of a 1024 x 1024 digital image with a FOV of 25 cm. 3. If we had the same FOV as #2, but changed the matrix size to 512 x 512, what is the pixel size or spatial resolution? Explain what happened in your own words. 4. If we had the same matrix size as #3, but had an FOV of 36 cm selected for our image, what would be the resulting pixel size, or spatial resolution? Explain how it is different and why in your own words. 5. How many bits are in 200 MB? 6. What is the storage capacity required for a 14 bit image captured on a 1024 x 1024 image matrix. Express your answer in MB.

00:01 Hello students, let's have a look on the question calculate the spectral resolution or pixel size of 1024 into 1024 digital image with the field of view of 25 centimeter.

00:10 What we have given here we have to find basically here pixel size.

00:14 So we know that pixel size formula is what simple we can say pixel size formula is what simply field of view field of view or divide by the size of the matrix.

00:27 In the question we have given the field of view is basically 25 centimeter and matrix size is what simply 1024.

00:35 Just put this formula values here in the formula 25 by 1024.

00:40 We will get the value of this matrix sorry field of pixel size is simply 0 .0244 centimeter.

00:47 This is the question number one that is given in this question.

00:50 Now moving on the question number two that is question number b.

00:53 What is the question is there? if we had the same field of view as question number first means we have the same field of view.

01:00 So field of view is same 25 centimeter, but the matrix size is now changed.

01:05 It is equal to 512.

01:07 So again we have to find the pixel size for the same question.

01:11 So again formula remains same for the pixel size.

01:14 So what we will do we will do like 25 by 512 and we will get the answer of this question is 0 .0488 centimeter.

01:27 Now again third question of this question is saying that if we had the same matrix size as 2, but had an field of view of 36 centimeter means we have again here given that m is equal to we have to take 512, but we have to change what we have to change the field of view that is equal to 36 centimeter...
