A comparison of relative stopping power derived by fast kV-switching dual-energy CT, single-energy CT, and proton CT in phantom and tissue. [PDF]
Med PhysAbstract Background The accuracy of relative stopping power (RSP) is a critical aspect for safe treatment planning in proton therapy. Dual‐energy CT (DECT) has the ability to estimate RSP more accurately than conventional single‐energy CT (SECT) due to its improved material separation. RSP accuracy is commonly determined in homogeneous phantom material

Comparison of three commercial multi-energy CT and electron density phantoms for iodine quantification and tissue substitute characterization. [PDF]
J Appl Clin Med PhysAbstract Background Multi‐energy computed tomography (MECT) and electron density (ED) phantoms are designed for evaluating the performance of CT scanners. They include substitute materials representing the energy‐ and material‐dependent CT numbers of different organs, tissues, or contrast agents.

Efficient Low Bit-Rate Low-Latency Channelization in DECT [PDF]
EURASIP Journal on Wireless Communications and Networking, 2006 In a TDMA standard such as DECT, low bit-rate transmission is feasible either at the cost of efficiency (shorter slots with fixed overhead per slot) or increased latency (longer frames).
