MEDICAL IMAGING AND IMAGE PROCESSING

1. 2. 3. Digitizing a medical image involves sampling and quantization processes. Why proper values are important for these two processes in medical imaging? Suppose we want to transmit the CT scan image over an internet connection with channel capacity at that moment is 100 Mb/sec. The image is 16-bit depth, 512 x 512 pixel resolution, and has 57 slices. How long will it take to deliver the image to the receiver? Explain how moir patterns are formed and how they are related to sampling rates and aliasing. What kind of digital images are most likely to result in moir effects when sampled? Histogram is a graph that shows the frequency or occurrence of each gray level existed in an image. For the 3-bit pixels image below, plot its histogram. 3 3 4 4. 4. 2 3 4 5 2 3 4 5 2 3 4 5
