    Abstract: The present disclosure provides a radiation detection system, a radiation output device, and a radiation detection device. The radiation detection system includes a radiation output device having an output control unit, and a radiation detection device having a recognition unit that recognizes whether radiation has been output from the radiation output device on the basis of a radiation detection signal. The output control unit causes radiation to be output at a first intensity from a time point of the start of outputting of radiation, and then causes the radiation to be output at a second intensity. The first intensity is an intensity higher than the second intensity and satisfying a threshold value condition set in advance in the recognition unit. The recognition unit recognizes that a detection signal of the radiation with the first intensity satisfies the threshold value condition, thereby recognizing the start of outputting of the radiation.

  • Patent number: 11049226
    Abstract: Local detail enhancement (LDE) is an imagery contrast enhancement method applied to visible and uncooled long wave imagery. It enhances local spatial detail through the use of a median based high/band pass filter. The generated detail channel is blended with a histogram-equalized version of the image, creating an image that contains both local detail as well as retaining some amount of global intensity. Retaining global intensity coherency allows for easier target acquisition when compared to fully local forms of contrast enhancement.

  • Patent number: 9668708
    Abstract: When an X-ray detector is removed from a storage part, a sensor senses this, and transmits to an up and down control part a signal indicating that the X-ray detector has been taken out of the storage part. Upon receipt of the signal, the up and down control part releases braking force by electro permanent magnets. In doing so, sticking force of the electro permanent magnet on a fixing part, and sticking force of the electro permanent magnet on a stopper plate are released. The weight of a counter weight is larger than the total value of the weights of the arm, X-ray tube, collimator, and the like, and therefore in a state where the arm is released from being fixed by the electro permanent magnets, the arm starts to move up together with the X-ray tube and the collimator.

  • Patent number: 9076237
    Abstract: Described here are a system and method for producing a statistical noise map that indicates the noise present in data acquired with an x-ray imaging system, such as an x-ray computed tomography system, an x-ray tomosynthesis system, a C-arm x-ray imaging system, and so on. In general, an image is reconstructed from the acquired data using, for example, any standard filtered back projection (“FBP”) image reconstruction algorithm. This image is used as a base line to estimate a noise standard distribution map. The raw projection data represents a typical measurement among many repeated measurements under the same experimental conditions; therefore, the measured projection data can be used to numerically generate an ensemble of many (e.g., twenty or more) noisy projection data sets. These noisy projection data sets are then used to reconstruct noisy images and from these noisy images and the original image, the statistical noise map can be computed.

  • Patent number: 8693628
    Abstract: To reduce X-ray exposure while improving image quality, an area of interest is selected in the image. The image of the selected area is updated frequently, comparable to a rate of updates used today for the whole image. The rest of the image is updated at a significantly lower rate. Since the area of interest normally is a small part of the overall area, the total exposure is reduced significantly. A fast X-ray shutter, placed near the X-ray source, blocks the radiation from areas outside the area of interest. The shutter automatically retracts when the complete image is updated. The area of interest can be selected by the user or automatically selected based on activity in the image. Since most of the exposures are taken at a reduced collimation angle, limited by the area of interest, the area of interest is imaged at reduced scatter and better quality.

  • Publication number: 20130259203
    Abstract: A radiation image capturing system and a console are described. The radiation image capturing system includes a radiation image capturing apparatus and a console. The console holds in advance a relationship between a number of the scanning line from which readout of the image data is started and an offset amount superimposed on the image data to be read out. When the preview image is displayed, the console modifies the relationship so that the starting point is moved to a position of the scanning line from which the radiation image capturing apparatus actually starts the readout, calculates the offset amount for each of the scanning lines, and displays the preview image based on a value obtained by subtracting the offset amount from the corresponding preview image data.

  • Patent number: 8542891
    Abstract: Positioning images are created by a projection-image creating unit before imaging, and the positioning images are grouped and stored by a projection-image storage unit for each preset. When imaging is started, a positioning-information calculating unit calculates positioning parameters using the positioning images stored in the projection-image storage unit. An analysis-image-for-synthesis creating unit creates an analysis image using the positioning parameters, and an analysis-image synthesizing and displaying unit synthesizes the analysis image with a live image and displays a synthesized image. When an imaging direction of an X-ray angiography apparatus is changed, a positioning-information updating unit directly updates the positioning parameters based on an amount of change of the imaging direction.
