Sensitivity compensation intensifying screens

Outline

Sensitivity compensation intensifying screens meet the requirement to produce a sharp image of a wider area of inspection. Their sensitivity varies corresponding to the areas to be inspected. Toshiba Materials offers two types of sensitivity compensation intensifying screens. One compensates one-dimensional sensitivity, and the other, two-dimensional sensitivity. Both types are suitable for ortho and regular films.

Specifications

One-dimensional sensitivity compensation intensifying screens

We offer screens that have a compensation ratio of 5, or screens that compensate sensitivity up to five times the minimum sensitivity. We have many compensation patterns such as standard, concave, convex and doubled concave as shown below.

One-dimensional sensitivity compensation intensifying screens

Two-dimensional sensitivity compensation intensifying screens

We offer intensifying screens that have patterned sensitivity compensation to correspond most suitably to the areas to be rayed. We have various patterns that correspond to frontal chest, lateral chest, lateral cervical vertebrae, shoulder joints, knee joints and panoramic radiography.

Two-dimensional sensitivity compensation intensifying screens

TYPE	Minimum sensitivity	Maximum sensitivity	Sensitivity enhancement ratio	Most suitable area to be rayed	Applicable films
LC	40–100	100–300	Two to five times	Upper and lower limbs, lateral area	Ortho films
QC	250–325	350–975			Regular films
EC	60–200	200 –500			Regular films

The relative sensitivity of intensifying screens to ortho films is denoted with the sensitivity of TO-220 being 100.
