A marker-coordinate detecting unit detects coordinates of a stent marker on a new image when the new image is stored in an image-data storage unit; and then a correction-image creating unit creates a correction image from the new image through, for example, image transformation processing, so as to match up the detected coordinates with reference coordinates that are coordinates of the stent marker already detected by the marker-coordinate detecting unit in a first frame. An image post-processing unit then creates an image for display by performing post-processing on the correction image created by the correction-image creating unit, the post-processing including high-frequency noise reduction filtering-processing, low-frequency component removal filtering-processing, and logarithmic-image creating processing; and then a system control unit performs control of displaying a moving image of an enlarged image of a set region that is set in the image for display, together with an original image.

X-ray diagnosis apparatus and image processing apparatus

A medical work support system according to an embodiment includes an interface apparatus, a reception unit, and a control unit. The interface apparatus accepts operation by the user, outputs a signal corresponding to the accepted operation, and is detachably attached to wearing clothing configured to be worn by the user. The reception unit receives a signal output from the interface apparatus. The control unit executes predetermined processing based on a reception signal received by the reception unit.

Medical work support system, surgical clothing, and medical apparatus

According to one embodiment, an X-ray diagnostic apparatus generating an X-ray image in a region of interest, includes a radiography device and processing circuitry. The radiography device takes a first X-ray image before injection of a contrast medium, and takes a second X-ray image and a third X-ray image after injection of the contrast medium. The processing circuitry generates an output image having pixel values that are ratios of pixel values between a difference between the second X-ray image and the first X-ray image and a difference between the third X-ray image and the first X-ray image.

X-ray diagnostic apparatus, image processing apparatus, and image processing method

When a plurality of X-ray images in a time sequence is stored in an image data storing unit (), a marker coordinate detecting unit (a) detects coordinates of a stent marker in each X-ray image, and a motion vector calculating unit (b) calculates, with coordinates of the stent marker detected in a first frame as reference coordinates, a motion vector of the coordinates of the stent marker detected in each X-ray image of a second and subsequent frames with respect to the reference coordinates. Then, a filter application range determining unit (c) moves and determines an application range of a smoothing filter in each X-ray image based on the motion vector, and the filtered image generating unit (d) generates a filtered image by performing a process by the smoothing filter between application ranges determined in a process target image and a reference image.

According to an embodiment, in an X-ray diagnosis apparatus, a detector detects a position of a feature point in the sequentially generated X-ray images. A corrector performs a correction process such that an angle of a line segment including the feature point and a single point based on the feature point detected in any one of the sequentially generated X-ray images substantially agree with an angle based on the feature point and a single point based on the feature point detected in a new X-ray image generated after the X-ray image, thereby sequentially generating corrected images in which a position different from the feature point in the images is substantially the same. Every time each of the corrected images is newly generated by the corrector, a controller sequentially generates the corrected images, thereby displaying a moving image on a display unit.

According to one embodiment, an X-ray imaging apparatus includes an X-ray image acquisition unit, a reference position acquisition part and a condition setting part. The X-ray image acquisition unit is configured to acquire frames of two dimensional X-ray image data corresponding to mutually different X-ray exposure directions using an imaging system. The reference position acquisition part is configured to obtain a spatially criterial direction and a spatially criterial position with reference to the frames of the X-ray image data. The condition setting part is configured to automatically set at least one of a control condition of the imaging system and an image processing condition of an X-ray image, based on information according to the criterial direction and the criterial position.

According to one embodiment, a medical image processing apparatus includes an X-ray image obtaining unit, a marker detection unit, a contrast image generation unit and a display image generation unit. The X-ray image obtaining unit obtains X-ray contrast image data and X-ray fluoroscopic image data. The marker detection unit detects positions of a marker from the X-ray contrast image data, or the X-ray contrast image data and the X-ray fluoroscopic image data. The marker is attached to a device. The contrast image generation unit generates X-ray contrast image data for a combination with a movement correction making the positions of the marker be positions which can be regarded as a same position. The display image generation unit generates X-ray image data for a display by combining the X-ray contrast image data for the combination with the X-ray fluoroscopic image data.

An X-ray imaging apparatus according to one embodiment captures an X-ray image by irradiating a subject with X-rays from an X-ray generating means, and detecting X-rays that have penetrated the subject with an X-ray detecting means, and includes a working-state detecting means and an X-ray dosage control means. The working-state detecting means detects a plurality of types of working-state information related to the working state of the operator performing surgery on the subject. The X-ray dosage control means, based on the plurality of types of detection results detected by the working-state detecting means, controls the X-ray dosage irradiated from the X-ray generating means.
