6. Ultrasonic Methods for Quantitative Carotid Plaque Characterization
Sammanfattning : Cardiovascular diseases are the leading causes of death worldwide and improved diagnostic methods are needed for early intervention and to select the most suitable treatment for patients. Currently, carotid artery plaque vulnerability is typically determined by visually assessing ultrasound B-mode images, which is influenced by user-subjectivity. LÄS MER
7. Image Quality Optimisation and Dose Management in CT, SPECT/CT, and PET/CT
Sammanfattning : The significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.

8. Fat-IBC : A New Paradigm for Intra-body Communication
Sammanfattning : In the last two decades, a significant development in the field of medical technology occurred worldwide. This development is characterized by the materialization of various body implants and worn devices, that is devices attached to the body. LÄS MER
9. Adolescent Idiopathic Scoliosis. The Role of Low Dose Computed Tomography
Sammanfattning : Continuous implementation of new operative methods for correction and stabilization of spinal deformities in young patients with AIS demands a detailed morphological analysis of the vertebral column. CT spine according to protocols available in daily clinical practice means high radiation dose to these young individuals. LÄS MER
10. Prospective Applications of Microwaves in Medicine : Microwave Sensors for Orthopedic Monitoring and Burn Depth Assessment
Sammanfattning : In recent years, the use of microwave techniques for medical diagnostics has experienced impressive developments. It has demonstrated excellent competencies in various modalities such as using non-ionizing electromagnetic waves, providing non-invasive diagnoses, and having the ability to penetrate human tissues within the GHz range.
