The ultrasound ellipsoid and erMRI ellipsoid methods appeared to overestimate ultrasound contoured volume by an average of 9.34% and 16.57% respectively. 33.33% of those who qualified for brachytherapy based on ellipsoid ultrasound volume would be disqualified based on ultrasound contoured and/or erMRI ellipsoid volume.

6.2 Area of a superellipse Formula 6.2.1 When n,a,b ()b a are positive numbers respectively and ()z is the gamma function, the area S of the ellipse of degreen is given by the following expression.

Sorry - I missed that. You have values for a, b, c, for the equation Right? The center of mass along the z-axis can be found from where V = volume of the half elipsoid, which is , and A(z) is the cross-sectional area as a function of z. The formula for the volume of an ellipsoid is as follows: V = 4 / 3 ⋅π⋅a⋅b⋅c. where: V is the volume of the ellipsoid; a, b and c are the lengths of the semi-axes; An ellipsoid is the most general shape in the class that includes: ellipsoid; oblate spheroid; sphere I need to calculate the volume of half an ellipsoid, split horizontally along the long axis. In effect, an oval shaped mound of soil. So the bottom would be an ellipse. I have the length, width and height measurements but not the formula. Thanks!

So let me draw our new ellipse first, just to show you what I'm doing. So our new ellipse is going to look something like that. I'm shifting the yellow ellipse down by two. So this equation, if I shift it down, well, the x is still where it was before. x minus 5 squared over 9 plus y plus 2 squared over 25 is equal to 1.
