The presented multi-energy detector has clear advantages over both the established dual-shot techniques –i.e.
absence of motion artifacts,
and easy integration into existing systems– and single-shot systems –namely,
higher dose efficiency,
and allowance for more complex algorithms.
This feasibility study shows that this type of design can generate tissue-subtracted images in a clinical setting,
and hence proves that these advantages can be delivered.
the DQE measurements show that this detector lives up to its promise of increased dose efficiency without the introduction of any new types of artifacts that degrade image quality.
We conclude that this multi-layer flat-panel X-ray detector design is a promising alternative to current DE techniques,
which can likely deliver high-quality DR and DE images without disrupting the imaging workflow.
Given its single-shot nature,
this detector could potentially expand DE imaging to real-time and mobile applications and increase its prevalence in radiology as a whole.
These results should be further validated with clinical subjects,
and the quality of the tissue-subtracted images compared with that of established DE techniques.
