  • Patent number: 11596351
    Abstract: Disclosed herein is a non-invasive system for determining tissue composition. The system comprises an imaging system with a non-invasive probe, a signal analyzer, and a correlation processor. The probe includes active imaging components for emitting energy and collecting imaging data including reflected signals from an object of interest. The signal analyzer analyzes the imaging data and determines one or more signal properties from the reflected signals. The correlation processor then associates the one or more signal properties to pre-determined tissue signal properties of different tissue components through a pattern recognition technique wherein the pre-determined tissue signal properties are embodied in a database, and identifies a tissue component of the object based on the pattern recognition technique.

  • Patent number: 10932740
    Abstract: A method for optimizing an X-ray imaging system during a mammographic examination. In order to provide an optimization of the X-ray imaging a breast is compressed between a support plate and a compression plate. A force-height curve is then acquired during the compression. An elasticity value of the breast is determined based on the force-height curve. A parameter of the X-ray imaging system is optimized based on the determined elasticity value.

  • Patent number: 10881358
    Abstract: The present invention relates to an apparatus for characterization of a feature in a body part. It is describe to provide (210) tomosynthesis medical data comprising a plurality of images of the body part, wherein the plurality of images comprise image data associated with a plurality of rays of radiation that have passed through the body part, wherein the image data comprises spectral data associated with at least two photon energy levels of the plurality of rays of radiation, wherein the medical data comprises data of the feature. A delineated boundary of the feature is determined (220). At least one material composition of the body part inside the delineated boundary is determined (240) comprising a function of the spectral data inside the delineated boundary. The feature is characterised (250) as a function of the at least one material composition inside the delineated boundary of the feature. Data representative of the feature is output (260).

  • Patent number: 10856850
    Abstract: An information processing apparatus includes acquisition units, calculation units, and a matching unit. The acquisition units acquire a position of a first reference point as a reference point, and a position of a first surface point as a point, on a surface of a target object in a first body posture. The acquisition units acquire a position of a second reference point as the reference point, and a position of a second surface point, on the surface of the target object in a second body posture. A distance between the first reference point position and the first surface point position is calculated as a first distance. A distance between the second reference point position and the second surface point position is calculated as a second distance. The matching unit matches the first and second surface points based on a relationship between the first and second distances.

    Abstract: A system for imaging biopsy samples obtained from a patient includes: a radiation source; a radiation detector having a surface that defines a first imaging region, a second imaging region, and a third imaging region; and a collimator having a body defining an opening and selectively adjustable between a first imaging position and a second imaging position. The first imaging position allows radiation rays to pass from the radiation source, through the opening, and into the second imaging region while restricting the radiation rays from passing into the first imaging region when the radiation source is in a first scanning position. The second imaging position allows radiation rays to pass from the radiation source, through the opening, and into the third imaging region while restricting the radiation rays from passing into the first imaging region when the radiation source is in a second scanning position.
