6. Evaluation of absorbed dose and image quality in mammography
Sammanfattning : Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. LÄS MER
7. Electropermeabilization in Experimental Tumour Treatment: Dosimetry and Tissue Effects
Sammanfattning : Short, electric high-voltage pulses can be used to transiently increase the permeability of cell membranes without significant loss of cell viability. During this period of time, extracellular and normally non-permeant, molecules are accessed the cytoplasm and the cell nucleus. LÄS MER
8. Development of Experimental Brachytherapy Dosimetry Using Monte Carlo Simulations for Detector Characterization
Sammanfattning : Brachytherapy (BT) is a type of interventional radiotherapy that is advantageous due to high absorbed dose conformity and possibility to deliver high dose in few fractions. It is often used for prostate and gynecological tumors as monotherapy or a boost alongside external beam radiotherapy (EBRT). LÄS MER
9. In vivo dosimetry of aldehydes and studies on the origin of malonaldehyde
Sammanfattning : Aldehydes are electrophilic reagents that bind to nucleophilic sites in macromolecules andmany of them have been shown to possess cytotoxic and genotoxic properties.The aim of this study was to develop an analytical method for the measurement of reactionproducts (adducts) of aldehydes with hemoglobin (Hb) and to apply this method for in vivodosimetry of endogenously formed aldehydes, particularly malonaldehyde (MA).

10. In vivo dosimetry of some alkylating agents as a basis for risk estimation
Sammanfattning : The present study concerns in vivo dosimetry of ultimate electrophilic reagents as a step in risk estimation of mutagenic and carcinogenic chemicals. The level of reaction products with nucleophilic groups in macromolecules could be used for dose determination. LÄS MER
