Abstract: Systems and methods for generating imaging biomarkers that indicate detectability or conspicuity of lesions that may be present in mammographic images are provided. In general, a task-based measure of a signal-to-noise ratio (“SNR”) measurement of a detection task is computed over a number of small regions-of-interest (“ROIs”) in an image, and the computed parameter is used to predict what detection rates should be if a lesion was present in the image. As such, the computed parameter can be used to define an imaging biomarker that is a “masking measure” that indicates the degree of conspicuity of lesions that may be present in a given a mammographic image.

Abstract: A tissue slicer system that includes a tissue slicing mold capable of producing very thin (e.g., on the order of 3 mm) and uniform slices to be captured from whole, fresh tissue specimens, notably breast lumpectomies, while minimizing distortion. These thin, uniform whole-specimen slices of the fresh surgical specimen increase the area of tissue available for inspection, reduce the amount of tissue lost in trimming during microtomy, and permit tissue processing for producing whole-mount sections.

Abstract: The present invention relates to a method of reconstruction of an object from projections, more particularly to a quantitative reconstruction of an object from projection views of the object. For example, quantitative reconstruction of an image of a human breast from projection views generated by digital breast tomosynthesis (DBT), computed tomography (CT), or standard mammography, and use of the reconstruction to identify densest regions.

Abstract: Disclosed is a method of analyzing tissue from an image comprising providing an electronic image of tissue (100, 400, 450, 600, 800, 1100), determining a reference value from the image (1070, 1170, 1270), establishing an hint representation (500,700) of the image, and using the hint representation in analysis of the tissue to quantify the breast and compute a calibration error. Also disclosed is a system which runs an inner breast edge detection algorithm (1310) on the electronic image to detect the inner breast edge on the image (1315), and refined the inner breast edge location (1340) if a calibration error is not acceptable (1324). Also disclosed is automatic estimation of breast composition and temporal analysis of images.

Abstract: An integrated application specific integrated circuit having a detection layer, a time delayed integration capability, data acquisition electronics, and a readout function is provided for detecting breast cancer in women. The detection layer receives x-ray radiation and converts the received energy to electron pairs, one of which is received by pixels. The time delay integration is on the chip and a part of the readout architecture. The detector may be a hybrid silicon detector (SiPD), a CdZnTe detector, or a GaAs detector.

Abstract: The disclosure includes computer implemented methods and devices comprising processors for inputting images and medical history into an electronic medium and analyzing x-ray images of a subject's breasts to determine density. The disclosure further contemplates using these methods and devices to generate a numerical value. The disclosure further contemplates using the numerical value to determine whether the subject should have magnetic resonance imaging of the breasts.
