Micro-Computed Tomography beamline (MCT)
Capability summary and techniques
The MCT beamline complements the existing X-ray imaging and tomography capabilities provided by the Imaging and Medical Beamline (IMBL), and targets applications requiring higher (sub-micron) spatial resolution and involving smaller samples. MCT is a bending-magnet beamline, operating with X-rays in the energy range of 8 to 40 keV. Monochromatic X-rays is selected using a double-multilayer monochromator (DMM). The DMM operates with a relatively bred energy bandpass (ΔE/E~3%) in beställning to increase the integrated flux at the sample position. The DMM can also be removed from the X-ray beam path, enabling experiments with a high flux, filtered white beam, for studies that require high-speed information acquisition. The photon-delivery system (PDS) has a single-(vertical) bounce spegel (VBM), capable of suppressing harmonic contamination in low-energy monochromatic beams and providing the means

Abstract
Background
The purpose of the study is to evaluate the physical performance of a Biograph mCT Flow 64-4R PET/CT system (Siemens Healthcare, Germany) and to compare clinical image quality in step-and-shoot (SS) and continuous table motion (CTM) acquisitions.
Methods
The spatial resolution, sensitivity, count rate curves, and Image Quality (IQ) parameters following the National Electrical Manufactures Association (NEMA) NU2-2012 standard were evaluated. For resolution measurements, an 18F point source inside a glass capillary tube was used. Sensitivity measurements were based on a 70-cm-long polyethylene tube, filled with 4.5 MBq of FDG. Scatter fraction and count rates were measured using a 70-cm-long polyethylene cylinder with a diameter of 20 cm and a line source (1.04 GBq of FDG) inserted axially into the cylinder 4.5 cm off-centered. A NEMA IQ phantom containing six spheres (10- to 37-mm diameter) was used for the evaluation of the image quality. First, a single-be
