Libra 40T 14” X 17” Tethered

Lightweight, Cassette-Sized Flat Panel Detector

Excellent Sensitivity & Resolution

・Advanced and proven fine structured CsI:Tl and direct vapor deposition technology deliver higher sensitivity and better resolution.

・Reflection coating on CsI:Tl screen enables excellent Detective Quantum Efficiency (DQE) and low noise.

・A high Modulation Transfer Function (MTF) FPI is the result of these outstanding technologies diagnostic images, while delivering the benefits of lower radiation dose to the patient. The Libra 40T achieves a new level of functionality and reliability in developing functional FPI’s for system manufacturers.

Excellent Image Quality

・Achieves a raw image with a low-noise through the use of circuit technology.

・Images have a shorter lag time with an improved refresh function, suitable for radiographic double exposure.

・Driver software (attached to the product) provides excellent, clear raw images, adopting ghost image correction , offset correction, gain correction and defect corrections.

Excellent Reliability

・Excellent durability by using CsI:Tl screen direct vapor deposition method.

・The structure is highly reliable and protected from degradation due to the use of a unique moisture-proof sealing method for the CsI:Tl screen.
