  • Patent number: 11710233
    Abstract: A machine-based learning method estimates a probability of bone fractures in a 3D image, more specifically vertebral fractures. The method and system utilizing such method utilize a data-driven computational model to learn 3D image features for classifying vertebra fractures. A three-dimensional medical image analysis system for predicting a presence of a vertebral fracture in a subject includes a 3D image processor for receiving and processing 3D image data of a 3D image of the subject, producing two or more sets of 3D voxels. Each of the sets of 3D voxels corresponds to an entirety of the 3D image and each of the sets of 3D voxels consists of equal 3D voxels of different dimensions. The system also includes a voxel classifier for assigning the 3D voxels one or more class probabilities each of the 3D voxels contains a fracture using a computational model, and a fracture probability estimator for estimating a probability of the presence of a vertebral fracture in the subject.

    Abstract: During orthopedic surgeries, body parts are moved in different ways to cause different anatomic features (e.g. muscles or the trochanters) to tighten or loosen, or become more or less prominent during the intended surgical incisions, which can result in easier surgical procedures. Body parts can be moved using a variety of different structures. The exemplary structures described herein can allow for: (1) a person's leg and foot to be rotated about the axis of the leg (i.e., femur/tibia axis); (2) a person's leg can be pivoted generally about the hip/femoral head/acetabulum to vary the angle between the axis of the leg and a median sagittal plane; (3) a person's leg can be moved in a direction parallel to the leg axis; and/or a person's leg can be pivoted in a generally vertical plane, about the femoral head/acetabulum while the axis of the leg and the median sagittal plane remaining substantially parallel.

The phantom assembly has slits where radiation sensitive film can be inserted and can include a channel for an insertable radiation generating device. The treatment dose is then applied to the phantom and the radiation sensitive film records the dose. A CCD camera microdensitometer is then used to read the exposed radiation sensitive film. The CCD camera microdensitometer includes a computer system which processes the image to remove artifacts and generates isodose contours for the radiation treatment applied. In addition, several pieces of radiation sensitive film in different planes can be exposed and processed in order to produce images representing the radiation dose distribution in three dimensions.

  • Patent number: 5237601
    Abstract: A cassette of the kind used for holding sheets of film to be exposed during x-ray of a patient is coded so that an x-ray technician or operator can easily distinguish cassettes containing exposed film from those cassettes containing unexposed film. This is accomplished by color coding two adjacent side edges of the cassette with color different from the other side edges of the cassette.

  • Patent number: 5228678
    Abstract: Disclosed is a disposable sheet cassette and an image forming apparatus in which such a sheet cassette is preferably employed. The sheet cassette is comprised of a cassette box capable of accommodating a plurality of sheet materials and having a flange portion extending outwards from the cassette box, an adhesive layer formed on the flange portion, and a sheet cover bonded on the adhesive layer for covering an opening of the sheet cassette. A portion of the sheet cover can be repeatedly separated from or applied to the adhesive layer to open or close the opening. The image forming apparatus is provided with a take-up roller movable above the sheet cover for winding the sheet cover, a pair of roller supports for rotatably supporting the take-up roller, a driving mechanism for moving the roller supports and for rotating the take-up roller, and a control system for operating the driving mechanism so that the take-up roller can wind the sheet cover after the sheet cassette has been charged in the apparatus.

    Abstract: A sheet extracting mechanism is provided with a suction cup for attracting one of stacked sheets, a negative pressure source for supplying a suction force to the suction cup, a detector for detecting the pressure in the suction cup, a moving mechanism for moving the suction cup thereby extracting the sheet adhered to the suction cup by the section force, and a discriminator for comparing the suction force in the suction cup with a predetermined pressure, at a predetermined position located a predetermined distance from the bottom of the stack of sheets, thereby identifying the amount of the stacked sheets. The suction cup is temporarily stopped at the predetermined position corresponding to a predetermined number of remaining sheets, and the remaining number of sheets is identified equal to or less than the predetermined number when the suction cup no longer touches the sheet, thereby becoming unable to attract the sheet.

  • Patent number: 5044009
    Abstract: The set of X-ray film holders for taking X-ray exposures of an entire tooth consists of a holder for the side teeth and a holder for the front teeth, each of the holders comprising a resilient clip for the X-ray film, a formed bite portion and a cranked indicator rod extending perpendicularly to the film plane for adjusting the central X-ray beam orthogonally to the film plane. The film clip is attached to the bite portion in such a manner that it is pivotable by 360.degree. and may be locked in the plane which is formed by the indicator rod with its cranked portion. Except for special X-ray tubes, it is useful to have a centering aid for the central X-ray beam. To this end, an index having pointer means is movably disposed on the indicator rod, guiding means being provided on the indicator rod and on the tube of the index in order to bring the pointer means into the correct position according to whether the X-ray film is in its upward or downward position.

    Abstract: An x-ray film magazine has a housing and a cover which in combination form an interior volume having an approximately C-shaped cross section, which receives a number of sheets of x-ray film in a stack made to conform to the C-shaped cross section. A foil is provided in the interior of the magazine having one end rigidly connected to a base of the housing, and an opposite end being resiliently connected to the cover of the magazine. The foil at least partially supports a bottom-most or lowest sheet of the stack of x-ray film sheets, and due to the resilient mounting of the foil, always presents the uppermost sheet in the stack of film sheets to be presented in a position which permits the uppermost sheet to be reliably conveyed out of the magazine to an exposure position in an exposure component adjacent the film magazine.

  • Patent number: H2117
    Abstract: Vari ramp blankets holding X-ray file, 14? by 17? in dimensions, in pockets on top of the vari-ramp inlets on an F-15 aircraft have been used by us for the detection of foreign objects, i.e. washers, bolts, safety wire. These blankets ensure inspection consistency each and every time the aircraft is X-rayed when it is grounded after flight or is in phase. The blankets are placed on top of the F-15 vari-ramp, taped securely in place and film is placed individually in the pockets. The placement and the consistency of results that the blankets provide enhances the accuracy and duplicability of the overall X-ray process.
