Characterization of imaging performance in differential phase contrast CT compared with the conventional CT—Noise power spectrum NPS(k)
Purpose: The differential phase contrast CT is emerging as a new technology to improve the contrast sensitivity of the conventional CT. Via system analysis, modeling, and computer simulation, the authors study the noise power spectrum (NPS)—an imaging performance indicator—of the differential phase...
