Directional sinogram interpolation for motion weighted 4D cone-beam CT reconstruction

Autor: Matthijs F. Kruis, Jan-Jakob Sonke, Hua Zhang

Publikováno v: Physics in medicine and biology. 62(6)

The image quality of respiratory sorted four-dimensional (4D) cone-beam (CB) computed tomography (CT) is often limited by streak artifacts due to insufficient projections. A motion weighted reconstruction (MWR) method is proposed to decrease streak a

PET motion compensation for radiation therapy using a CT-based mid-position motion model: methodology and clinical evaluation

Autor: Jeroen B. van de Kamer, Antonetta C. Houweling, Jan-Jakob Sonke, Matthijs F. Kruis, Marcel van Herk, José Belderbos

Publikováno v: International journal of radiation oncology, biology, physics, 87(2), 394-400. Elsevier Inc.

Purpose Four-dimensional positron emission tomography (4D PET) imaging of the thorax produces sharper images with reduced motion artifacts. Current radiation therapy planning systems, however, do not facilitate 4D plan optimization. When images are a

Background In contemporary positron emission tomography (PET)/computed tomography (CT) scanners, PET attenuation correction is performed by means of a CT-based attenuation map. Respiratory motion can however induce offsets between the PET and CT data

4D CT amplitude binning for the generation of a time-averaged 3D mid-position CT scan

Autor: Marcel van Herk, Jan-Jakob Sonke, Jeroen B. van de Kamer, José Belderbos, Matthijs F. Kruis

Publikováno v: Physics in medicine and biology, 59(18), 5517-5529. IOP Publishing Ltd.

The purpose of this study was to develop a method to use amplitude binned 4D-CT (A-4D-CT) data for the construction of mid-position CT data and to compare the results with data created from phase-binned 4D-CT (P-4D-CT) data. For the latter purpose we

Registration accuracy and image quality of time averaged mid-position CT scans for liver SBRT

Autor: Matthijs F. Kruis, Marcel van Herk, Jan-Jakob Sonke, Jeroen B. van de Kamer, Edwin P.M. Jansen

Publikováno v: Radiotherapy and oncology, 109(3), 404-408. Elsevier Ireland Ltd

Purpose and background The purpose was to validate the accuracy of motion models derived from deformable registration from four-dimensional computed tomography (4DCT) and breath-hold contrast enhanced computed tomography (BHCCT) scans for liver SBRT.
