Tips and tricks

There is no auto save-function in Prism. If you exit Prism or open a new case any changes made to the previous case after it was archived or checkpointed will be lost!
Adding a beam which doesn’t contribute to your dose (i.e. MU 0) can be useful, to create a Beam’s Eye View of which the dose distribution is independent (if this beam is altered the isodose levels will disappear anyways and a new dose calculation has to be done). In setting the colour of this beam to “Invisible”, mix-up with the other beams can be avoided.
When pressing the ruler button, sometimes the ruler is not visible in the picture area due to a bug in the program. In this case, close the View (or other according) panel and re-open it. The function should work then.
