Description of the RTI Slit Camera
The RTI Slit Camera for x-ray focal spot measurement comes with a stand with an
adjustable rod. Optionally also a tilting device is available.
Figure 2-1 Slit Camera with (left) and without (right) the optional tilting device.
The Slit Camera can be rotated 90 degrees in the Slit Camera holder. See figure 2-2
below. The 90 degree rotation simplifies the measurement of length and width
measurements of the focal spot since the slit only have to be aligned once.
Figure 2-2 The Slit Camera can be rotated by means of 90 degrees.
The optional tilting device enables measurements where the reference position is not
orthogonal to the image plane, which is normal in mammography. See figure 2-3 below.
