Motion artifact and partial volume effect caused underestimation of coronary plaque inﬂammation. This study evaluated the high matrix acquisition technique using time-of- ﬂight (TOF) positron emission tomography/computed tomography for imaging of atheroscle- rotic plaque inﬂammation with ﬂuorine-18 ﬂuorodeoxyglucose in small and moving phantoms. Methods and Results. All images were reconstructed using a conventional algorithm without TOF (4 3 4 3 4mm voxel size) and a high matrix algorithm with TOF (2 3 2 3 2mm voxel size). Microsphere phantoms of 10, 7.9, 6.2, 5.0, and 4.0 mm diameters were acquired in 3-dimensional list-mode for 30 minutes. A heart phantom mimicking cardiac motion consisted of a
