Comparison of ghosting effects for three commercial EPIDs

Medical Physics, 2006
Many studies have reported dosimetric characteristics of amorphous silicon electronic portal imaging devices (EPIDs). Some studies ascribed a non‐linear signal to gain ghosting and image lag. Other reports, however, state the effect is negligible. This study compares the signal‐to‐monitor unit (MU) ratio for three different brands of EPID systems.

Electrophoretic image display (EPID) panel

Proceedings of the IEEE, 1973
A new reflective-type electrophoretic image display (EPID) panel is described which is based on electrophoresis. In the EPID panel, a suspension is mainly composed of pigment particles and a suspending liquid. A dc voltage applied across a suspension layer changes the reflective color of the suspension as a result of the electrophoretic migration of ...
