Simpson’s protocol is used for calculation left ventricular volume from

measurements taken in two scan planes. The calculation of volume for both

methods (2-chamber or the 4-chamber view) results from summation of areas from

diameters of 20 cylinders or discs of equal height, apportioned over the left
