Channelography

If a crystalline thin foil is irradiated by means of an isotropic source of charged particles, the particles channeled in the sample leave on a detector an image called channelography.

Transmission radiography can also be subdivided into: (i) neutron radiography; (ii) ion radiography; (iii) ion lithography; and (iv) ion channelography.

From the author's experience, provocative gonioscopy and channelography are useful to determine the overall status of the individual case before surgical intervention.
