Question

The question is in the image

b) The T1-weighted image in the figure represents a slice though the abdomen, with signals coming from liver, kidney, tumour and lipid. Given the following information: P(liver) = p(kidney) < p(lipid) < p(tumour) and the spectral density plot shown below: J(@) kidney tumour liver liver, kidney tumour fat @1 @2 @z fat (a) Determine at which frequency (w1, w2, W3 0r w4) the image was acquired, and give your reasons. (b) At which of these frequencies (w1, w2, w3 or W4) would the relative signal intensities of the four tissues be reversed, i.e. the highest becomes lowest and vice-versa?
