  1. 11. Chewing gum and human hair as retrospective dosimeters

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Axel Israelsson; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Retrospective dosimeters are sometimes needed after radiological/nuclear (RN) exposures to determine the doses to individuals. Conventional dosimeters may not be at hand or may not be applicable calling for alternative materials. LÄS MER

  2. 12. Studies of radioactive cisplatin (191Pt) for tumour imaging and therapy

    Detta är en avhandling från Radiaiton Physics, Malmö University Hospital, SE-205 02 Malmö, Sweden

    Författare :Johan Areberg; Lunds universitet.; Lund University.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytology; mice; in vitro; gamma camera; tumour imaging; platinum pharmacokinetics; cisplatin; radioactive; oncology; cancerology; Cytologi; onkologi; cancer;

    Sammanfattning : A radioactive variant of the cytostatic agent cis-dichlorodiammineplatinum(II), cisplatin, was synthesised from 191PtCl4. The 191Pt-cisplatin was found to be a sterile product of high radionuclide, radiochemical and chemical purity. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; 131-I; Clinical physics; SPECT; conjugate-view; volume quantification; activity quantification; image registration; image segmentation; medicinsk instrumentering; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

    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

  4. 14. 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

  5. 15. 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
