Respiratory Motion Estimation Using a 3D Diaphragm Model
Long acquisition times of several seconds lead to image artifacts in cardiac C-arm CT. These artifacts are mostly caused by respiratory motion. In order to improve image quality, it is important to accurately estimate the breathing motion that occurred during image acquisition. It has been shown that diaphragm motion is correlated to the respiration-induced motion of the heart. We present a met...
متن کاملThe Predictive Value of Abdominal Ultrasonography Compared to CT Scan for the Evaluation of Pediatric Lymphoma
Background: Given the children's susceptibility to the harmful radiation of computerized tomography (CT) scans, ultrasonography can be a good alternative in staging pediatric lymphoma. The present study aimed to assess the predictive value of abdominal ultrasonography compared to CT scan in children with lymphoma. Materials and Methods: Fifty-two children with confirmed lymphoma were included ...
متن کاملDiaphragm Tracking for Respiratory Motion Compensated Cardiac C-Arm CT
Long acquisition times of several seconds lead to image artifacts in cardiac C-arm CT. While ECG gating is able to select a certain heart phase, residual artifacts are mostly caused by respiratory motion. In order to improve image quality, it is important to accurately estimate the breathing motion that occurred during image acquisition. It has been shown that diaphragmmotion is correlated to t...
