An apparatus and a method are provided for positioning an x-ray machine having an x-ray source and a detector. A second X-ray image is recorded once an x-ray apparatus has been positioned by using information of an alignment point in a first x-ray image.

An image processing apparatus comprises processing circuitry. The processing circuitry is configured to acquire a first image in which each pixel is expressed with a first gradation. And the processing circuitry is configured to specify a partial region in the first image. And the processing circuitry is configured to convert, based on correspondence information that associates each level of the first gradation with a display pattern of a plurality of pixels in a display, the level in the first gradation of each pixel included in the partial region in the first image into the corresponding display pattern, the display displaying the display pattern with a second gradation having fewer levels than the first gradation. And the processing circuitry is configured to generate a second image that expresses a plurality of pixels included in the partial region of the first image as the converted display patterns.

A system and method for displaying images of internal anatomy includes an image processing device configured to provide high resolution images of the surgical field from low resolution scans during the procedure. The image processing device digitally manipulates a previously-obtained high resolution baseline image to produce many representative images based on permutations of movement of the baseline image. During the procedure a representative image is selected having an acceptable degree of correlation to the new low resolution image. The selected representative image and the new image are merged to provide a higher resolution image of the surgical field. The image processing device is also configured to provide interactive movement of the displayed image based on movement of the imaging device, and to permit placement of annotations on the displayed image to facilitate communication between the radiology technician and the surgeon.

During the generation of a panoramic x-ray recording, the use of semi-transparent x-ray screens allows the patient's x-ray exposure to be reduced when partial x-ray images are created, in spite of relatively large overlapping areas between the partial x-ray images.

The invention relates to a cardiac lead extraction system, comprising: a handle; an elongated body in communication with said handle; a bendable flexible portion in communication with said elongated body, said bendable flexible portion comprising a first lumen sized and shaped to fit over a cardiac lead; said bendable flexible portion being more flexible than said elongated body; an operational distal end in communication with said bendable flexible portion; where said bendable portion is configured to bend to a bending radius of less than 4 cm while keeping said first lumen open; and where said operational distal end comprises at least one lead extraction assistive tool, said operational distal end comprising a second lumen sized and shaped to fit over a cardiac lead, said second lumen being in communication with said first lumen, and said first lumen comprises an inner diameter of from about 1 mm to about 5 mm.

The present disclosure provides an image processing device including: a radiographic image acquisition section that acquires a radiographic image, the radiographic image generated by stitching together radiographic images of an imaging subject imaged by plural radiation detectors, each of which includes a detection face for detecting radiation; a purpose acquisition section that acquires information indicating an interpreting purpose; and an adding section that adds a predetermined assist line to the radiographic image, on the basis of at least one of a reference object corresponding to the interpreting purpose in the radiographic image acquired by the radiographic image acquisition section or the information indicating the interpreting purpose.

A medical image obtaining apparatus includes: an image obtainer, which comprises an X-ray emitter configured to emit X-rays toward an object and an X-ray detector configured to detect X-rays that have penetrated the object, and is configured to obtain an image of a portion of the object based on the detected X-rays; a controller configured to generate a virtual ruler which indicates information about a location of the image, based on a rotation angle of the X-ray emitter; and a display configured to display the virtual ruler on the image.

An image processing system according to an embodiment includes a first aligning unit, an output unit, a second aligning unit, and a display unit. The first aligning unit aligns first three-dimensional medical image data with second three-dimensional medical image data. The output unit outputs, as output data, data obtained by adding alignment information to the first three-dimensional medical image data and to the second three-dimensional medical image data or synthetic data obtained by aligning and synthesizing the first three-dimensional medical image data with the second three-dimensional medical image data. The second aligning unit receives the output data and aligns the second three-dimensional medical image data with one or a plurality of pieces of X-ray image data. The display unit displays image data obtained by aligning the first three-dimensional medical image data with X-ray image data based on an alignment result.

The present disclosure relates to a system and method for medical imaging. An imaging device having a table may be provided. Scans of a subject located on the table at multiple table positions may be performed based on a scanning protocol, each scan covering a portion of the subject. Data may be acquired based on the scans of the subject. An image may be reconstructed based on the acquired data.

An X-ray CT apparatus is provided which can easily decide on a reconstruction method based on imaging conditions. The X-ray CT apparatus comprises an irradiation unit irradiating a subject with X-rays, a detector configured to detect X-rays transmitted through the subject, and a rotator rotating irradiation unit and detector around the subject, and which generates an image by receiving biological signals of the subject to perform synchronous imaging. A memory stores a threshold value. Processing circuitry calculates, based on imaging conditions related to the synchronous imaging, a detection data amount in which detection data amount detected by the detector is represented by a number of rotations of the rotator, decides, based on the detection data amount and the threshold value, on a reconstruction process for implementation on the detection data, and implements reconstruction processes based on the detection data to generate the image.
