Open AccessCombining virtual monoenergetic imaging and iterative metal artifact reduction in first-generation photon-counting computed tomography of patients with dental implants
While established for energy-integrating detector computed tomography (CT), the effect of virtual monoenergetic imaging (VMI) and iterative metal artifact reduction (iMAR) in photon-counting detector (PCD) CT ...

Open AccessQuantitative and qualitative image quality assessment in shoulder examinations with a first-generation photon-counting detector CT
Photon-counting detector (PCD) CT allows for ultra-high-resolution (UHR) examinations of the shoulder without requiring an additional post-patient comb filter to narrow the detector aperture. This study was de...

Open AccessMetal artifact reduction in ultra-high-resolution cone-beam CT imaging with a twin robotic X-ray system
Cone-beam computed tomography (CBCT) has been shown to be a powerful tool for 3D imaging of the appendicular skeleton, allowing for detailed visualization of bone microarchitecture. This study was designed to ...

Open AccessOne-stop-shop CT arthrography of the wrist without subject repositioning by means of gantry-free cone-beam CT
Modern cone-beam CT systems are capable of ultra-high-resolution 3D imaging in addition to conventional radiography and fluoroscopy. The combination of various imaging functions in a multi-use setup is particu...
