Segmentation of the sternum from low-dose chest CT images
Segmentation of the sternum in medical images is of clinical significance as it frequently serves as a stable reference to image registration and segmentation of other organs in the chest region. In this paper we present a fully automated algorithm to segment the sternum in low-dose chest CT images (LDCT). The proposed algorithm first locates an axial seed slice and then segments the sternum cr...
متن کاملClinical Value of Low Dose CT- Scan in Pediatric Chest Diseases: Adequacy Assessment
Background Radiation dose about 400 times that of standard thoracic computed tomography (CT) in comparison with chest X- ray resulting in different approaches to decrease radiation dose have been established in the last few years to prevent possible side effects especially in children, such as low dose protocols. The aim of this study was assessment of clinical v...
متن کاملSegmentation of Individual Ribs from Low-dose Chest CT
Segmentation of individual ribs and other bone structures in chest CT images is important for anatomical analysis, as the segmented ribs may be used as a baseline reference for locating organs within a chest as well as for identification and measurement of any geometric abnormalities in the bone. In this paper we present a fully automated algorithm to segment the individual ribs from low-dose c...

متن کاملCombining Automatic Tube Current Modulation with Adaptive Statistical Iterative Reconstruction for Low-Dose Chest CT Screening
OBJECTIVE To reduce radiation dose while maintaining image quality in low-dose chest computed tomography (CT) by combining adaptive statistical iterative reconstruction (ASIR) and automatic tube current modulation (ATCM). METHODS Patients undergoing cancer screening (n = 200) were subjected to 64-slice multidetector chest CT scanning with ASIR and ATCM. Patients were divided into groups 1, 2,...
