A physics primer on photon‐counting detectors in CT: Physics, signal formation, and performance

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Photon‐counting detector CT (PCD‐CT) is moving from laboratory development to clinical deployment. However, its threshold‐bin data arise from a tightly coupled detector–readout chain that can be difficult to understand as a whole. These data are not a direct readout of photon energy, but the outcome of a sequence of physical and electronic ...

Experimental quantification of frame‐level active window duration and duty cycle in high frame rate x‐ray detectors

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Detector frame rate is commonly used as the primary metric to characterize the temporal behavior of x‐ray detectors in medical imaging systems. However, frame rate alone specifies only the sampling rate of image frames and does not determine how x‐ray interaction signals are temporally integrated to form the measured signal within ...

Calcium Solubility of Bridgmanite in Subducted Basalt in Earth's Lower Mantle

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The calcium solubility in bridgmanite and the resulting abundance of davemaoite under lower‐mantle pressure‐temperature conditions have been under debate following a recent report of extensive calcium dissolution in bridgmanite. We experimentally investigated the calcium solubility in bridgmanite in a basaltic composition at pressures up to ...
