DOI: 10.1002/acm2.12821
Abstract: Abstract The circular‐edge technique using a low‐contrast cylindrical object is commonly used to measure the modulation transfer functions (MTFs) in computed tomography (CT) images reconstructed with iterative reconstruction (IR) algorithms. This method generally entails averaging… read more here.

DOI: 10.1002/mp.16306
Abstract: BACKGROUND Arrays of thick segmented crystalline scintillators are useful x-ray converters for image-guided radiation therapy using electronic portal imaging and cone-beam megavoltage computed tomography. Ionizing-radiation-only simulations previously showed relatively low modulation transfer function (MTF) in… read more here.

DOI: 10.1007/s11605-021-04911-8
Abstract: Multiple tumor foci (MTF) in intrahepatic cholangiocarcinoma (ICC), including satellitosis and true multifocality, is a known negative prognostic factor and can inform pre-operative decision-making. Lack of standardized pre-operative liver staging practices may contribute to undiagnosed… read more here.

DOI: 10.1093/nar/gkab474
Abstract: Abstract Metal-induced genes are usually transcribed at relatively low levels under normal conditions and are rapidly activated by heavy metal stress. Many of these genes respond preferentially to specific metal-stressed conditions. However, the mechanism by… read more here.
