AbstractPurpose of ReviewThe purpose of this review is to provide the readers with current information and state-of-the-art of digital scanning systems within the orthodontics. Introducing the commercially available intraoral and facial scanning systems, as well as bringing future perspectives to these systems.Recent FindingsThe emergence of digital scanners associated with computer-aided design is one of today ’s key diagnostic tool enhancements in orthodontics. Among the main applications in orthodontics, it is the analysis for diagnosis, treatment planning, and prediction of the final result. There is a range of p...

Authors: Guo L, Chen B, Zhang L, Deng Y, Li H, Shi QD Abstract A 49-year-old female patient developed chest tightness and shortness of breath without apparent cause and presented to a local hospital. Chest radiography indicated increased thickening of the lung texture, increased multiple patchy densities in the lower lobes of the bilateral lungs and a slightly enlarged thyroid. The patient was treated for pulmonary infection with antibiotics but the symptoms persisted. A repeated CT scan revealed ground-glass attenuation of the bilateral lungs with multiple flaky exudates and visible bronchogenic signs. The symptom...

Authors: Xu J, Wang X, Xiao H, Xu J Abstract BACKGROUND To determine the difference in size-specific dose estimates (SSDEs), separately based on effective diameter (deff) and water equivalent diameter (dw) of the central slice of the scan range in computed tomography coronary angiography (CTCA). MATERIAL AND METHODS There were 134 patients who underwent CTCA examination, were electronically retrieved. SSDEs (SSDEdeff and SSDEdw) were calculated using 2 approaches: deff and dw. The median SSDEs and mean absolute relative difference of SSDEs were calculated. Linear regression model was used to assess the absolute rel...

This study aimed to propose an automatic recognition and volume calculation for the inferior turbinate and maxillary sinus by using image processing techniques. The back propagation neural network (BPNN) was used for automatic recognition of the inferior turbinate and maxillary sinus. Parametric template matching (PTM) and the sub-region similarity were used as feature inputs. The level set method (LSM) was applied to circle the contour of the inferior turbinate and maxillary sinus. The marching cubes algorithm was employed for 3D reconstruction and visualization. The volume information was obtained from the nonlinear regr...
