    Abstract: A medical imaging system adaptively acquires anatomical images using a shape adaptive collimator including multiple different portions of X-ray absorbent material automatically adjustable to alter the dimensions of a spatial cross section of an X-ray beam of radiation into a non-rectangular shape, in response to a control signal. The synchronization processor provides a heart rate related synchronization signal derived from a patient cardiac function related parameter. The synchronization signal enables adaptive variation in timing of image acquisition within an individual heart cycle and between successive heart cycles of each individual image frame of multiple sequential image frames. The X-ray image acquisition device uses the shape adaptive collimator for acquiring anatomical images of the region of interest with reduced patient X-ray exposure in response to the synchronization signal. A display processor presents resultant images.

  • Patent number: 8157443
    Abstract: The disposable radiograph cassette cover is formed of two sheets of x-ray transparent pliable material having a low coefficient of friction to facilitate sliding the cover and contained cassette beneath a patient for the radiography procedure. The cover includes distinctively colored integral radiopaque anatomical markers disposed over a portion of the film or plate in the cassette to shield that portion of the underlying plate during the procedure. The plate is thus automatically marked during the procedure to show the side of the body where the cassette and cover were placed. The cassette is sealed within the cover by an adhesive flap, with the adhesive and/or release sheet also being color-coded to indicate the side to which the cover is to be used. The cassette is removed from the cover by tearing off the adhesively sealed end along provided perforations.

  • Patent number: 8009804
    Abstract: Systems and methods for developing a treatment plan for irradiating a treatment volume within a patient are disclosed. In accordance with the present invention, control points used to calculate a dose of radiation delivered to the treatment volume may be combined to result in a smaller number of control points. The smaller number of control points may allow more efficient calculation of dose distributions resulting in a treatment plan that can be delivered to the patient earlier or may allow additional iterations of treatment plan optimization resulting in a more accurate dose distribution being delivered to the patient.

  • Patent number: 7986767
    Abstract: An actual-past-radiography position database stores, as actual-past-radiography positions, the position of a radiographic image detector and the position of a radiation source when radiography was actually performed, associating the position of the radiographic image detector and the position of the radiation source with information about a subject. When the radiation source and the radiographic image detector are positioned to perform radiography, position adjustment amounts for adjusting the positions of the radiation source and the radiographic image detector from standard positions stored in the standard position database are output, as aid information. The aid information is output based on the actual-past-radiography positions that are stored in the actual-past-radiography position database and that are associated with the information about the subject.
