A 3T MRI scanner used is tuned for proton imaging. For a given imaging sequence applied to image a patient's leg the gradient strength is 1 G/cm, FOV is 25 cm, and matrix is 250x250. The patient has a titanium screw in their leg that causes a magnetic susceptibility change to the main magnetic field of 0.5 Gauss. How much shift is image position ( in pixels) will be seen in this part of the leg?

Problem Let's suppose that there are three frames overlapping each other at the beginning, namely {A}, {B} and {C}. Then, both frames {B} and {C} are translated by 5 centimeters in x and y axis directions and rotated rotated about z axis by 30 degrees in the counter-clockwise direction with respect to frame {A}. Finally, frame {C} is translated by 10 centimeters in the x axis direction and 20 centimeters in the y axis direction and rotated rotated about z axis by 60 degrees in the clockwise direction with respect to frame {B}. Given coordinates (4,-4) of point P with respect to frame {C}, determine the coordinates of point P with respect to frame {A}. NOTE: ATC= ATB. BTC Robotic
