Find the local contrast and SNR of the object comprising the nine pixels at the center of the camera .

An Anger camera collimator has the following dimensions: septal thickness h = 6 mm, septal height l = 10 cm, and hole diameter d = 3 mm. The detector thickness is b = 2.5 cm. The range z = 0.5 m.

(a) Find the collimator resolution.

(b) Suppose the intrinsic resolution of the Anger camera is 0.2 mm. Write an expression for the intrinsic PSF assuming it is Gaussian.

(c) Find the overall resolution of the Anger camera.

The final image (static frame mode) on the Anger camera is shown in Figure P8.10.

Figure P8.10 See Problem 8.21.

(d) Find the total count of the scan.

(e) Find the local contrast and SNR of the object comprising the nine pixels at the center of the camera .

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….
