What are the reasons for developing forminglimit diagrams?

What are the reasons for developing forminglimit diagrams? Do you have any specific criticisms of such diagrams? Explain. The reasons for developing the FLD diagrams

 

are self-evident by reviewing Section 7.7.1. Criticisms pertain to the fact that:

(a) the specimens are still somewhat idealized,

(b) frictional conditions are not necessarily representative of actual operations, and

(c) the effects of bending and unbending during actual forming operations, the presence

of beads, die surface conditions, etc., are not fully taken into account.

Explain why attenuation is not a big problem in PET.

Consider a 2-D object consisting of two triangle compartments, as shown in Figure P9.4. Suppose a solution containing a 511 KeV gamma ray emitting radionuclide with concentration f = 0.5….

Give the mean and the variance of the reconstructed image, mean[ˆ f(x, y)] and var[ˆ f(x, y)].

Ignoring the inverse square law and attenuation, an approximate reconstruction for SPECT imaging is given by where c˜() =  {||W()} and W() is a rectangular windowing filter that cuts off at = 0…..

Find the numerical responses in each to an event in crystal C(4, 6).

Suppose a PET detector comprises four square PMTs (arranged as a 2 by 2 matrix) and a single BGO crystal with slits made in such a way that it is….
