1. Evaluation of image quality and diagnostic accuracy in breast tomosynthesis. Comparison with digital mammography and estimates of radiation risk
Sammanfattning : Recent advances in the digital detector technology have paved the way for modalities such as two-dimensional digital mammography (DM) and three-dimensional breast tomosynthesis (BT). In this work, experimental studies were conducted to investigate the influence of reducing the average glandular dose (AGD) on detection of simulated lesions in DM and to compare the diagnostic accuracy of BT and DM.

2. Quantifying the quality of medical x-ray images. An evaluation based on normal anatomy for lumbar spine and chest radiography
Sammanfattning : Optimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. LÄS MER
3. Prior Knowledge and Recognition Memory : a Computational Modeling Approach
Sammanfattning : For more than a century, an immense interest has been devoted to the study of recognition memory, where a multitude of memory phenomena has been explained. Recognition memory is usually described with parsimonious measurement and statistical models, stemming from dual process theory and signal detection theory. LÄS MER
4. Mental illness and criminal behavior : individual characteristics related to criminal conduct among violent offenders with schizophrenia
Sammanfattning : During the last decades, interest has increased in structured risk assessment of future violence as well as in research addressing the link between schizophrenia and violence. The overall aim of this study was to extend our knowledge concerning risk assessment and the connection between schizophrenia and criminal behavior. LÄS MER
5. Personality disorder and violent criminality : a follow-up study with special reference to psychopathy and risk assessment
Sammanfattning : Background: Structured models for the assessment of psychopathy and risk of violent recidivism have gained currency in forensic and correctional practice in many countries. The overall aim of this study was to test the predictive validity of some of these models among violent offenders with personality disorders in Sweden. LÄS MER
