Risk‐minimizing tube current and tube voltage modulation for CT: A simulation study Open
Background The optimal tube voltage in clinical CT depends on the patient's attenuation and the imaging task. Although the patient's attenuation changes with view angle and longitudinal position of the X‐ray tube, the tube voltage remains …

CT material decomposition with contrast agents: Single or multiple spectral photon‐counting CT scans? A simulation study Open
Purpose With the widespread introduction of dual energy computed tomography (DECT), applications utilizing the spectral information to perform material decomposition became available. Among these, a popular application is to decompose cont…

Patient radiation risk reduction by controlling the tube start angle in single and dual source spiral CT scans: A simulation study Open
Background Organ doses in spiral CT scans depend on the tube start angle. Purpose To determine the effective dose in single source CT (SSCT) and dual source CT (DSCT) scans as a function of tube start angle and spiral pitch value to identi…

Image quality of opportunistic breast examinations in photon-counting computed tomography: A phantom study Open
Clinical PCCT provides an image quality superior to that obtained with BCT in terms of CNRD and allows for the identification of calcifications and fibers at comparable dose levels.

Two-View Topogram-Based Anatomy-Guided CT Reconstruction for Prospective Risk Minimization Open
To facilitate a prospective estimation of CT effective dose and risk minimization process, a prospective spatial dose estimation and the known anatomical structures are expected. To this end, a CT reconstruction method is required to recon…
