The detector presampling MTF of the VRX CT scanner was modeled by Monte Carlo simulation. Because the VRX detector was a 1D discrete array, the MTF modeling was done by “moving”, with a very small ...

Purpose To develop an easily-implemented technique with free publicly-available analysis software to measure the modulation transfer function (MTF) and noise-power spectrum (NPS) of a clinical ...

Abstract: The modulation transfer function (MTF) is well known as a crucial parameter in quality assurance of computed tomography (CT) scanners, which provides detailed information of both contrast ...

Abstract: High contrast resolution(HCR) is an important performance parameter of the computed tomography(CT) scanner. The assessment of HCR is regularly performed by measuring the modulation transfer ...

本講演では，Deep Learning Reconstruction（DLR）の現状を述べた上で，次世代のDLRであるキヤノンメディカルシステムズの超解像画像再構成“Precise IQ Engine（PIQE）”の使用経験を報告する。 DLRの現状 CTの画像再構成法は，以前から用いられているfiltered back projection ...
