Anyway, back to tubes. What do you reckon about the feasibility of prolonging the usefulness of old (deteriorating) x-ray tubes by employing the "magic" (digital processing) of CR? Perhaps you have already done (or are now doing) this?
Taking into account that CR systems allow a local calibration (Shading calibration) applying a theoretical dose of 20uG.
If we intervene in conjunction with a non-invasive meter of radiographic values ??we can adjust the final image result of the CR for an adequate quality, discarding the metallization and aging of the tube that degrade performance. This allows us to make a relative adjustment to the site (Hermanar CR with RX emitter). The meter we use has an ionization chamber so there is an extra supervision of the 20uG value.
