  • Patent number: 11311267
    Abstract: A method of position planning for a recording system of an imaging device with respect to a selectable field of view of a patient includes acquiring current position information of the recording system and/or the imaging device, and/or setting information of a collimator of the imaging device. A current intersection volume between an X-ray beam and the patient and/or a current field of view is determined. The current intersection volume and/or the current field of view is determined as a virtual display element. A target intersection volume and/or a target field of view is received by manipulation of the virtual display element. A target position of the recording system and/or the imaging device, and/or the setting of the collimator is determined, such that, on occupying the target position, the target intersection volume and/or the target field of view becomes the current intersection volume and/or current field of view.

  • Patent number: 11304675
    Abstract: Methods and devices for testing effects of external stimuli on breast appearance in an x-ray image are provided. A model for testing may include a breast phantom with an encapsulated hydrogel. In some examples, a three-dimensional cell culture and/or microfluidic channels may be encapsulated in the hydrogel. A first set of x-ray images of the model may be captured, thermal energy may be applied to the model, and a second set of x-ray images of the model may be captured while the thermal energy is being applied for comparison with the first set to determine effects of the thermal energy on appearance of the model. By incrementally increasing an amount of thermal energy applied and capturing subsequent x-ray images for comparison, an appropriate temperature range may be determined for heating compression surfaces of a breast imaging system to reduce compression-related pain and discomfort for patients without compromising x-ray image quality.
