A 3D Forward and Back-Projection Method for X-Ray CT Using Separable Footprint
The computation burden of cone-beam forward and back-projectors is one of the greatest challenges facing iterative methods for 3D image reconstruction in CT. This paper describes a new separable footprint (SF) projector. It takes advantage of small polar angles of X-rays in cone-beam geometry to approximate the voxel footprint functions as 2D separable functions with simple rectangular function...
متن کامل3D Forward and Back-Projection for X-Ray CT Using Separable Footprints with Trapezoid Functions
The greatest impediment to practical adoption of iterative methods for X-ray CT is the computation burden of cone-beam forward and back-projectors. Moreover, forward and back-projector accuracy is also crucial to iterative reconstruction methods. We previously described a computationally efficient projector that approximates the voxel footprint functions by the 2D separable products of trapezoi...
متن کاملInvestigation of dosimetric characteristic of NIPAM polymer gel using x-ray CT
Introduction: Polymer gel dosimeters contain chemical materials sensitive to the radiation which are polymerized by the radiation as a function of absorbed dose. So information of spatial dose distribution can be extracted by imaging from irradiated gel. Among imaging techniques, computed tomography (CT) poses as an attractive method because of practical advantages such as acce...
متن کاملSoft-x-ray projection lithography
Soft-x-ray projection imaging is demonstrated by the use of 14-nm radiation from a laser plasma source and a single-surface multilayer-coated ellipsoidal condenser. Aberrations in the condenser and the Schwarzschild imaging objective are characterized and correlated with imaging performance. A new Schwarzschild housing, designed for improved alignment stability, is described.
متن کاملreproducible x-ray projection geometry in endodontic practice
introduction: clinical application of radiography in endodontic practice is affected by reproducibility in the orientation of the x-ray source, image receptor and object. the inability of dentists to locate intra oral films or sensors in appropriate positions in different cases can cause complications in the performance of endodontic therapy. commercially available film holder (endoray) and con...
