1. Impact of Tissue Characteristics on Radio-Frequency Lesioning and Navigation in the Brain : Simulation, experimental and clinical studies
Sammanfattning : Radio-Frequency (RF) lesioning, or RF ablation, is a method that uses high frequency currents for thermal coagulation of pathological tissue or signal pathways. The current is delivered from an electrode, which also contains a temperature sensor permitting control of the current at a desired target temperature. In the brain, RF lesioning can e.g. LÄS MER
2. Thermocoagulation in Deep Brain Structures : Modelling, simulation and experimental study of radio-frequency lesioning
Sammanfattning : Radio-frequency (RF) lesioning is a method utilising high frequency currents for thermal coagulation of pathological tissue or signal pathways. The current is delivered from an electrode with a temperature sensor, permitting control of the current at a desired target temperature. In the brain RF-lesioning can e.g. LÄS MER
3. New techniques in liver surgery
Sammanfattning : The development of liver surgery has a long history and through the years, much knowledge has been gathered concerning various aspects of the liver. The exploration and understanding of liver anatomy and liver regeneration and development of surgical techniques are important landmarks. LÄS MER
4. Characterisation of brain electrodes for ablative neurosurgery
Sammanfattning : Stereotactic ablative neurosurgery with radio frequency current is regularly performed on patients with movement disorders, for instance Parkinson's disease. Even though the technique has been used for ablation in the brain for almost 50 years, nobody has suggested a standardised way of testing the electrodes used for ablative surgery. LÄS MER
5. Irreversible electroporation in the liver
Sammanfattning : Introduction: Malignant tumours in the liver are divided into primary liver cancers and liver metastases. Among primary liver cancers, hepatocellular carcinoma (HCC) accounts for 75-85% and is globally the fourth most common cause of cancer related death. Colorectal cancer (CRC) is the second most common cause of cancer related death. LÄS MER
