The Essential Physics of Medical Imaging
Pinhole collimators are used extensively in pediatric nuclear medicine. A
converging collimator (Fig. 21-6) has many holes, all aimed at a focal point in
front of the camera. As shown in Fig. 21-6, the converging collimator magnifies
the image.

Emission Tomography: The Fundamentals of PET and SPECT
Although this selective absorption is necessary for the creation of the images, it is
also very inefficient because most of the gamma rays are absorbed in the
collimator. For the collimators used in nuclear medicine, only about one in ten ...

Medical Imaging Physics
FIGURE 12-3 With a parallel multihold collimator, γ rays emitted in line with the
collimator holes are transmitted to the crystal, whereas γ rays emitted obliquely
are absorbed by the collimator septa. As the diameter of the collimator cylinders
is ...

Figure 11 displays the experimentally-measured response of two types of
collimators: a smooth-sided collimator and a disk-loaded collimator. For
reference, the response of an ideal collimator (no scattering) is also shown.
These collimators ...

Sensitivity An estimate of the sensitivity of a collimator can be computed from
simple geometry. A useful measure is the sensitivity of the collimator per unit area
of collimator to a plane source of activity placed in front of it. It is easily shown
from ...
