  1. 11. A multi-prism lens for hard X-Rays

    Författare :Björn Cederström; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray; optics; refractive; lens; mammography; synchrotron; Physics; Fysik;

    Sammanfattning : This thesis describes a new type of refractive lens for hardx-rays. It is shown that a linear array of prisms, slightlyinclined with respect to the optical axis, will form a linefocus at a certain distance from the lens. Hence, the namemulti-prism lens. LÄS MER

  3. 12. MICROWAVE IMAGING OF BIOLOGICAL TISSUES: applied toward breast tumor detection

    Författare :Tommy Gunnarsson; Ylva Bäcklund; Denny Åberg; Hans Sköld; Mikael Persson; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave Imaging; Breast tumor detection; Inverse problems; Mammography; Electronics; Elektronik; Elektronik;

    Sammanfattning : Microwave imaging is an efficient diagnostic modality for non-invasively visualizing dielectric contrasts of non-metallic bodies. An increasing interest of this field has been observed during the last decades. Many application areas in biomedicine have been issued, recently the breast tumor detection application using microwave imaging. LÄS MER

  4. 13. Ultrasensitive Molecular Monitoring of Breast Cancer and Acute Myeloid Leukemia

    Författare :Yilun Chen; Translational Oncogenomics; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; AML; PTEN; PI3K; Liquid biopsy; Sequencing; cfDNA; ctDNA; Structural variants; Mammography; CTC; Mutation detection; IBSAFE; MRD;

    Sammanfattning : Cancer is the common name to a group of biologically diverse malignant neoplastic diseases. Approximately 18 million people are diagnosed with cancer annually and 8.8 million patients die from it. Tumorigenesis and progression of cancer are driven by alterations in the cancer cell genome.

  5. 14. 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

  7. 15. Breast cancer screening in an urban, Swedish population Aspects of non-attendance, interval cancers and over-diagnosis

    Författare :Sophia Zackrisson; Kardiovaskulär forskning - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiologi; mammography; epidemiology; Folkhälsa; Public health; non-attenders; socio-economic factors; lead time; interval cancer; over-diagnosis; service screening; breast cancer screening;

    Sammanfattning : Service screening with mammography was implemented in Sweden in the late 80's, following the results from trials in Sweden and abroad. A high rate of attendance, a high diagnostic accuracy and treatment in accordance with established guidelines are key circumstances for an effective screening programme. LÄS MER
