This system allows 3D X-ray scanning of patients in standing and weight-bearing position. In particular, high spatial resolution enables adequate visualization of bone structures. The results show that the system delivers high image quality for a range of medical applications. Furthermore, initial evaluation of patient dose is conducted. We provide an initial evaluation of the 3D image quality based on phantom scans and clinical images. Projection data for 3D cone-beam CT reconstruction can be acquired during simultaneous movement of the arms along dedicated scanning trajectories. 2D radiographs and fluoroscopic image sequences can be obtained from different viewing angles. This system is equipped with two motor-driven telescopic arms carrying X-ray tube and flat-panel detector, respectively. In this work, we provide an initial characterization of a novel twin robotic X-ray system. Scholz, Rosemarie Ritschl, Ludwig Mertelmeier, Thomas Twin robotic x-ray system for 2D radiographic and 3D cone-beam CT imagingįieselmann, Andreas Steinbrener, Jan Jerebko, Anna K. Feasibility studies of CT reconstruction have been performed by making simulated Cr images of various phantoms for larger flash x-ray systems of from 8 to 29 flash x-ray tubes. The effects of accelerations of up to 600 g were examined on radiographs taken of human kidney tissue samples in a rapidly rotating centrifuge. To demonstrate the ability of the system to image traumatic events, a radiograph was obtained of a bone undergoing a fracture. We have written and tested a stereo reconstruction algorithm to determine three dimensional space points from corresponding points in the two stereo images. The dynamic and static Miff 's for the flash x-ray system were measured and compared with similar MIT's measured for a conventional medical x-ray system. We have built a two channel flash x-ray system capable of producing stereo radiographs with stereo angles of from 15 to 165 degrees. This type of imaging device will be valuable in studying high speed processes, high acceleration, and traumatic events. We are developing a flash x-ray scanner for stereoradiography and CT which will be able to produce a stereoradiograph in 30 to 70 ns and a complete CT scan in one microsecond. All non-classified materials inspectionĪ high contrast, fine grain film with medium contrast combining good image quality and wide latitude.Development Of A Flash X-Ray Scanner For Stereoradiography And CTĮndorf, Robert J.Castings and other multi-thickness objects.The wide latitude films are specially designed for in-house radiography and to inspect wide range thickness objects such as castings.Īn extra fine grain film with medium contrast and very high speed. The film can be used for direct exposure techniques or with lead screens. If even higher speed is required, fluorescent screens, in combination with F8 (not D8), should be used. It gives good image quality with short exposure times. This film can be used for direct exposure or with lead screens. Medium grain film with high contrast and very high speed. For exposure with lead screens, using either X-ray or gamma rays. Designed for direct exposure or with lead screens. This film is intended for use with lead screens, using either X-ray or gamma rays.įine grain film with high contrast and high speed. Excellent for visualization of discontinuities. For exposure with lead screens, using either X-ray, gamma rays or radiation from megavolt equipment. Suitable for a wide variety of critical applications. Ultra fine grain film with very high contrast. For exposure with lead screens, using either X-ray, gamma rays or radiation from megavolt equipment. This film obtains a very high detail perceptibility, which meets the requirements of the most critical NDT applications. Ideal for exposures requiring the finest possible detail rendering.
