BrightForm CsI
High brightness, non-rigid Caesium Iodide (CsI) scintillators for x-ray imaging
Scintacor produces an affordable alternative to FOP-based CsI scintillators, with a thin non-glass substrate replacing the Fibre Optic Faceplate.
With FOP-based scintillators (diagram below), the x-rays strike from the ‘tips’ side of the CsI layer and the emitted light is extracted from the opposite ‘base’ side of the layer, passing through the x-ray blocking FOP into the sensor chip.
BrightForm CsI extracts light in the same orientation, but allows the FOP (if required) to be applied to the sensor independently, making visual inspection of the bond possible. The BrightForm CsI scintillator can be press fitted to the x-ray blocking FOP (diagram below) or directly onto the sensor.
Simplified Assembly
Alternatively, the FOP can be left out to reduce cost and weight (diagram below), but with no x-ray blocking layer between the CsI and the sensor, incoming x-rays pass into the sensor much more readily.
The two graphs below show the typical CsI thickness dependence of the brightness and resolution for BrightForm CsI versus a typical FOP-based scintillator.
Why Scintacor?
Our technologies are used in a wide variety of applications across x-ray, UV, EUV, IR, electron and neutron, detection and imaging. Trust our phosphor and scintillator expertise to optimise performance for your specific application.
Features & Benefits
- High brightness micro-columnar CsI scintillator layer
to maximise signal while maintaining resolution. - Lightweight, non-rigid substrate desirable for large area and portable detectors.
- Delamination resistant by design to improve robustness of the sensor.
- Customisable size and shape with edge-to-edge coating to maximise the active area of any sensor.
- Choice of CsI thickness to balance brightness, SNR,
and resolution; from thin layers used in intra-oral dental devices, to much thicker layers for high energy and high SNR x-ray applications. - High sensitivity solid state scintillator to reduce patient x-ray dose.
- Low-cost PET substrate which is especially significant for large area detectors.
Custom Shapes and Sizes
From simple to complex shapes, with edge-to-edge coating, and custom sizing to maximise the active area of any sensor.
