  1. 1. Improving breast cancer screening with artificial intelligence

    Författare :Victor Dahlblom; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breast cancer; artificial intelligence; screening; mammography; breast tomosynthesis; bröstcancer; artificiell intelligens; screening; mammografi; brösttomosyntes;

    Sammanfattning : Introduction: The current standard method for breast cancer screening is digital mammography (DM). Digital breast tomosynthesis (DBT) can detect more cancers but is more resource-demanding, not the least due to a more time-consuming reading, which hinders the implementation in screening. LÄS MER

  3. 2. Optimization of breast tomosynthesis: Computer simulations of image acquisition and glandular dose

    Författare :Hannie Förnvik; Malmö Medicinsk strålningsfysik; []
    Nyckelord :breast tomosynthesis; Monte Carlo simulation; acquisition parameters; software breast phantom; microcalcifications; breast density; glandular dose; glandular distribution;

    Sammanfattning : Breast tomosynthesis (BT) is an X-ray imaging technique recently introduced as an alternative or complement to standard digital mammography (DM) in breast imaging and breast cancer screening. In BT, a set of projection images is acquired over a limited angular range and reconstructed into a volume of slice images. LÄS MER

  4. 3. Measurement of Tumor Extent and Effects of Breast Compression in Digital Mammography and Breast Tomosynthesis

    Författare :Daniel Förnvik; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; digital mammography; breast tomosynthesis; breast compression; pressure distribution; breast cancer; circulating tumor cell;

    Sammanfattning : Breast cancer is the most common form of cancer affecting women in the western countries. Today x-ray digital mammography (DM) of the breast is commonly used for early detection of breast cancer. However, the sensitivity of mammography is limited, mainly due to the fact that a 3D volume is projected down to a 2D image. LÄS MER

  5. 4. Spectral image quality and applications in breast tomosynthesis

    Författare :Karl Berggren; Mats Danielsson; Mats Lundqvist; Erik Fredenberg; Paul E. Kinahan; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical Technology; Medicinsk teknologi;

    Sammanfattning : In the 1970s, it was determined that screening mammography is an efficient tool in fighting the increasing number of women dying from breast cancer, and many countries have established screening programs since then. Mammography systems have improved substantially over the years with one of the major advances being the transition from x-ray film to digital x-ray detectors. LÄS MER

  7. 5. Breast tomosynthesis – new perspectives on breast cancer screening

    Författare :Kristina Lång; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Breast tomosynthesis; Mammography; Breast cancer screening; Cancer detection rate; Recall rate; False positive rate; Image perception; Reading time; Lesion visualisation; Detection error;

    Sammanfattning : Abstract: Mammography is currently the established method in breast cancer screening, although the sensitivity is known be affected by overlapping tissue concealing tumours. Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. LÄS MER
