filmQA pro™ image registration
Film image registration determines the film position relative to the coordinates of the delivered field represented by the isocenter of the radiation machine. The scanned image must have fiducial marks.
Fiducial marks are either directly related to the position of the iscocenter which is part of the treatment plan - e.g. fiducials may mark the x and y positions of the isocenter on the film or Fiducials form are pattern that is also available at the treatment plan - e.g. fiducials mark special locations at the used phantom which are also marked on the plan.
or
Fiducials form are pattern that is also available at the treatment plan - e.g. fiducials mark special locations at the used phantom which are also marked on the plan.
With FilmQA Pro one can solve the following tasks:
- register fiducial marks on a dose map towards isocenter position on the plan image (see Isocenter Fit)
- register fiducials marks on a dose map towards a similar fiducial pattern on the plan image (see Pattern Fit)
- methods to detect fiducials automatically on an image (see Registration Templates)
