    Sammanfattning : Popular Abstract in Swedish Behandling med radionuklidterapi baseras på radioaktiva läkemedel, d.v.s. läkemedel som i sig består av ett radioaktivt ämne, eller som kopplats till en radionuklid. LÄS MER

  2. 17. Live Single Cell Imaging and Analysis Using Microfluidic Devices

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Mohammad Ali Khorshidi; KTH.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Single cell analysis; time-lapse fluorescence imaging; automated image analysis; microwell; droplet microfluidics; NK cells; single cell tracking; migration behavior analysis; cell-cell interaction; optical microscopy; image analysis; image processing; microfluidics; immune cells; tracking; counting; morphology analysis;

    Sammanfattning : Today many cell biological techniques study large cell populations where an average estimate of individual cells’ behavior is observed. On the other hand, single cell analysis is required for studying functional heterogeneities between cells within populations. LÄS MER

  3. 18. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography

    Detta är en avhandling från Medical Radiation Physics, Lund University

    Författare :Mark Ruschin; Lunds universitet.; Lund University.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D breast imaging; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; hybrid images; dose reduction; spatial resolution; pixel size; Breast cancer; digital mammography; radiologi; tomografi; medicinsk instrumentering; breast tomosynthesis;

    Sammanfattning : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. LÄS MER

  4. 19. Activity quantification based on scintillation camera imaging - Application to 111In/90Y radioimmunotherapy

    Detta är en avhandling från Medical Radiation Physics, Lund University

    Författare :David Minarik; Lunds universitet.; Lund University.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radioimmunotherapy; bremsstrahlung imaging; activity quantification; SPECT; conjugate view; Yttrium;

    Sammanfattning : Radionuclide therapy (RNT), is important for the treatment of certain benign and malignant diseases. 90Y-Zevalin™ therapy has become an established method of treating patients with non-Hodgkin B-cell lymphoma. LÄS MER

  5. 20. Guidance and Visualization for Brain Tumor Surgery

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Filipe Miguel Maria Marreiros; Linköpings universitet.; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Image guidance and visualization play an important role in modern surgery to help surgeons perform their surgical procedures. Here, the focus is on neurosurgery applications, in particular brain tumor surgery where a craniotomy (opening of the skull) is performed to access directly the brain region to be treated. LÄS MER
