  • Patent number: 10433795
    Abstract: Disclosed are a radiation imaging system, an image processing device, a radiation imaging method, and a non-transitory computer-readable recording medium having an image processing program recorded thereon which facilitate the confirmation of a positional relationship between an object of interest and a biopsy needle. In the system using a radiation imaging device as a mammography device, when performing a biopsy of a breast of a subject, the positional relationship is confirmed using a radiation image (projection image) obtained through tomosynthesis imaging. A control unit reconstructs the projection image to generate a tomographic image in a state where the needle is inserted into the breast and generates a reprojection image at a predetermined angle from the tomographic image. The control unit extracts an image of the needle from the projection image, synthesizes the extracted image of the needle into the projection image while aligning, and displays the projection image.

  • Patent number: 8509381
    Abstract: A patient positioning system for a panoramic dental radiation imaging system, including an upright support, and a patient positioning arm with chin rest mounted thereto. Wands are each rotatably connected to the patient positioning arm and connected together so as to move at identical angles of rotation, but in the opposite direction. Lasers, including a mid-sagittal, a Frankfort Plane, two cuspid, and one toe laser, each providing a line of visible laser light directed at a respective area of a patient's face, or at the floor, assist a technician in properly positioning the patient. A mirror is mounted to the upright support by a mechanism that permits the mirror to be pivoted outward from the support, in either of two directions, so as to enable the technician to see the lasers on the patient's face from the technician's position on either side of the positioning arm.

  • Patent number: 8506163
    Abstract: An X-ray CT apparatus has a plurality of projectors, a reception unit, a setting unit, a supporter, and a scan execution unit. The projectors each have a light source on a circumference having a same radius as a rotation radius of an X-ray focal point of an X-ray irradiator and each irradiate laser light having an irradiation range simulating an irradiation range of the X-ray. The reception unit receives an instruction for three-dimensionally sliding the projectors as one body. The setting unit sets a position of the projectors. The supporter supports a table and three-dimensionally slides the table by a difference between a position of a center of the circumference of the set projectors and a position of a rotation center of the X-ray focal point of the X-ray irradiator. The scan execution unit executes a scan with the table after the sliding as a scan position.

  • Patent number: 8226295
    Abstract: In various exemplary embodiments, a targeting device providing a visible indication of an invisible beam is disclosed. The invisible beam, such as an x-ray beam, is emitted by a radiation source on a medical imaging system. The targeting device includes, for example, an illumination source to produce a visible beam and operate at one or more wavelengths. The illumination source, which is opaque to the x-ray beam and would ordinarily cause shadows on the imaging system, is arranged to be mounted outside of a field-of-view of the invisible beam. A beam reflector is mounted next to the illumination source. The beam reflector is fabricated from a material invisible to x-rays and is arranged to be mounted within the field-of-view of the invisible beam. The beam reflector redirects the visible beam produced by the illumination source such that the visible beam is parallel to the field-of-view of the invisible beam.
