High resolution X-ray imaging system

Scintillator | High resolution X-ray imaging system

 

High-durability single-crystal scintillator revolutionizes conventional imaging

Various types of high-durability single-crystal phosphor screen has been added that enables imaging at much higher X-ray flux density than before.

Synchrotron radiation white X-ray

Scintillator

Even when white X-ray is incident, stable imaging and measurement are realized for a long time.

Measurement conditions
Beam line SPring-8 BL28B2
X-ray energy White
Attenuator Air (9 m), Aluminum (0.034 mm), Be window (1 mm thick on the beam line side + 0.5 mm thick on the detector side)
Beam size 3×3 mm2
Detector Adhesive type: AA40 (f = 50 mm) + ORCA®-Flash2.8 (f = 35 mm)
Direct bonding type: AA40 (f = 50 mm) + ORCA®-Flash4.0 (f = 50 mm)
Pixel resolution Adhesive type: 5.1 μm/pixel, direct bonding type: 6.5 μm/pixel
Scintillator LuAG (Thickness: conventionally about 20 μm, high-durability single-crystal phosphor screen about 20 μm)*

* AA40 is used for durability evaluation. The single-crystal phosphor screen is not recommended for use with AA40.
