  1. 1. Methods for selection and optimisation of radiotherapy and early therapy evaluation in breast cancer

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tomas Jansson; Uppsala universitet.; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Breast cancer; human; radiotherapy; multi-leaf collimator; breast-conservingsurgery; local recurrence; p53; positron emission tomography; chemotherapy evaluation; Onkologi; MEDICINE Surgery Oncology; MEDICIN Kirurgi Onkologi; Oncology; onkologi;

    Abstract : Adjuvant systemic therapy for breast cancer, the most common malignancy in females, increases survival and this has recently also been demonstrated for postoperative radiotherapy. The aims of this study were to develop an optimised radiotherapeutic technique for postoperative treatment, to analyse the association between p53 status in node-negative patients and radiotherapy, to investigate the incidence of in-breast relapses after conservative surgery and radiotherapy and to determine if positron emissiontomography could be useful for early evaluation of polychemotherapy.

  2. 2. On perfusion estimation using ultrasound

    University dissertation from Department of Electrical Measurements, Lund University

    Author : Tomas Jansson; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; Speckle; Artifacts; Perfusion; Ultrasound; Doppler; Mät- och instrumenteringsteknik;

    Abstract : This thesis has the main focus on ways to improve the blood perfusion estimate, as obtained from a continuous wave Doppler system. Earlier studies have shown large temporal variations in the detected perfusion estimate, due to speckle. READ MORE

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Tomas Jansson; Linköpings universitet.; Linköpings universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The potential of using simulation and optimization techniques in the design of sheet metal forming processes has been investigated. Optimization has been used in a variety of sheet metal forming applications. READ MORE

  4. 4. Optimization of sheet metal forming processes

    University dissertation from Linköping : Linköpings universitet

    Author : Tomas Jansson; Linköpings universitet.; Linköpings universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The aim of the present work is to find a stable and effective optimization algorithm that can be used to determine the location and size of drawbeads in sheet metal forming processes. The result from the optimization will be the restraining force that each drawbead applies to the blank. READ MORE

  5. 5. Combining the tactile resonance method and Raman spectroscopy for tissue characterization towards prostate cancer detection

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Stefan Candefjord; Luleå tekniska universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Abstract : Prostate cancer (PCa) is the most common male cancer in Europe and the US, and only lung and colorectal cancer have a higher mortality among European men. In Sweden, PCa is the most common cause of cancer-related death for men. READ MORE
