| 20100104070 | Radiographic apparatus - For Respiration Correlated Cone Beam CT scanning, we have observed that improvements in the frame rate are in fact undesirable. We therefore propose a radiographic apparatus comprising a beam of radiation and a detector therefor, adapted to obtain a two dimensional image of the beam after passing through a cyclically varying object to be investigated, a processor adapted to review the images and select images at like points in the cycle, and a control means for the beam of radiation adapted to activate the beam periodically. The control means can activate the beam at a frequency of between 0.5 and 5 Hertz, more preferably between 1 and 3 Hertz, which corresponds (roughly) to a frequency that is between 6 and 10 times the frequency of the cyclical variation. It will assist if the selected point of the cycle is an extremity thereof, as the rate of change in these areas is at a minimum. Thus, slight mismatches between the two cycles will then have only a small effect. Typically, the object will be a patient and the cyclical variation will be the patient's breathing cycle. | 04-29-2010 |

| 20110075810 | RADIATION IMAGING APPARATUS AND IMAGING CONTROL DEVICE - A motor controller determines a drive speed of a motor for driving a filter such that an area shifting cycle of the filter synchronizes with a cardiac cycle. The filter starts to rotate before radiation emission, and continues to rotate at a constant speed during two successive radiation emissions. An emission controller controls timing of two emissions in accordance with a phase of the filter. The area shifting cycle of the filter and the cardiac cycle are previously synchronized, and thus a high-performance filter switching device for switching or shifting the filter in synchronization with the emission timing becomes unnecessary. Adjusting the area shifting cycle of the filter in accordance with the cardiac cycle realizes two radiation emissions in two successive cardiac cycles. As a result, an exposure time is shortened. | 03-31-2011 |

| 20120027177 | INDUSTRIAL X-RAY TUBE - An industrial X-ray tube formed by accommodating a cathode and anode in a container having an evacuated interior, in which electrons emitted from the cathode are caused to strike the anode and X-rays are emitted from the anode.

| 20120057678 | SYSTEMS AND METHODS FOR TEMPORAL MULTIPLEXING X-RAY IMAGING - The present subject matter relates to systems and methods for temporal multiplexing x-ray imaging of dynamic objects with high temporal resolution and fast imaging speed. A pulsed x-ray beam can irradiate an object undergoing a range of motion such as a cyclic motion. Multiple x-ray images can be acquired at different phases within a single motion cycle or range of the object. The multiple x-ray images can be demultiplexed to produce an individual phase image. Compared to sequential imaging, temporal multiplexing x-ray imaging can achieve high temporal resolution of dynamics object in multiple phases with imaging time comparable to that of a single phase. Temporal multiplexing x-ray imaging can thus be applied to a wide variety of applications, including biomedical imaging and industrial non-destructive testing. | 03-08-2012 |
| 20120294427 | METHOD FOR REMOVING MOTION FROM NON-CT SEQUENTIAL X-RAY IMAGES - Applicant has disclosed a method for removing motion from non-CT cardiac angiographic or fluoroscopic x-ray 2-D sequential images, without using data prediction techniques in sequential CT imagery. Applicant's results are achieved by actively deleting or skipping exposure of certain 2-D flash image acquisitions during rapid heart motion (e.g., beating), the latter to reduce x-ray exposure. Applicant's preferred method comprises: positioning a person relative to a non-CT type x-ray machine, designed for fluoroscopy or angiography, with the person's heart between an x-ray source and a detector; monitoring rapid movement of the person's heart by electrocardiography; generating a series of x-ray pulses from the x-ray source; actively skipping any x-ray pulses by switching off the x-ray source during beating of the person's heart to prevent any images being generated from the skipped x-ray pulses; and generating sequential (i.e., either angiographic or fluoroscopic) 2-D cardiac images from the non-skipped x-ray pulses; wherein the motion is removed from the sequential images without using predictive algorithms and without using estimated compensation of motion. | 11-22-2012 |

| 20140270081 | DYNAMIC CONTROL OF RADIATION EMISSION - Among other things, one or more techniques and/or systems for selectively inhibiting radiation from being generated by a radiation source are provided. A radiation source comprises an electrically conductive gate situated between a cathode and an anode. When a voltage potential is created between the gate and the cathode, a flow of electrons between the cathode and the anode is mitigated, thus inhibiting radiation from being generated by the radiation source. When the voltage potential is removed or lessened, electrons may more freely flow between the cathode and the anode to generate radiation. In some embodiments, a calibration, such as a dark calibration, may be performed while the gate mitigates the flow of electrons. Moreover, in some embodiments, an accelerating voltage applied to the radiation source may be held substantially constant when radiation is generated as well as when radiation generation is inhibited. | 09-18-2014 |
