摘要： According to one aspect of an exemplary embodiment of the disclosure, an imaging device or system (10), e.g., a mammography imaging system or device (12), includes a breast holding pad (200) disposed on one or both of a compression paddle (28) and a compression surface (50) on the imaging device (10). The breast holding pad (200) is formed with a central layer (202), a first, securing adhesive layer (204) on one side (205)of the central layer (202) and a second, biocompatible adhesive layer (206) disposed on the opposite side (207) of the central layer (202). The biocompatible adhesive (204,206) operates to securely hold the breast (52) during any imaging and/or biopsy procedure performed utilizing the imaging system (10). Further, with the use of one or both pads (200), the amount of compression force required to hold the breast (52) in a stationary position between the compression paddle (28) and the compression surface (50) can be reduced, thereby decreasing the discomfort to the patient during the imaging and/or biopsy procedure performed.

摘要： The invention proposes to combine spectral image data with non-spectral image data in order to overcome limitations of the different data taking methods. Results from the methods are preferably combined as functions of spatial frequency so that spectral image data provide high accuracy at low frequencies, whereas the non-spectral image data helps reducing the noise at high frequencies. The invention enables a range of applications in different fields of X-ray imaging such as improved tissue contrast and tissue characterization.

摘要： Die Erfindung betrifft ein Verfahren zur Darstellung eines interessierenden Bereichs innerhalb eines Untersuchungsobjekts (O), in das ein Untersuchungsinstrument (8) eingebracht ist. Es wird mittels eines Tomosynthesesystems (2) ausgeführt und umfasst zumindest folgende Schritte: Aus einer Anzahl von seitlichen Akquisitionswinkeln (A1, A2, A3, ..., A6) werden Rohdatensätze (RD) erfasst (ACQ). Aus den Rohdatensätzen (RD) wird eine Anzahl von synthetischen Projektionen (SP) ermittelt (CAL). Die synthetischen Projektionen (SP) werden als Bildsequenz (AD), welche das Untersuchungsobjekt (O) rotierend darstellt, ausgegeben (DIS). Weiterhin werden eine Bildrekonstruktionseinrichtung (10) sowie ein Tomosynthesesystem (1) beschrieben.
