1. Evaluation of intrafractional motion for patients receiving whole brain radiotherapy in open-faced immobilisation masks
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/Background Patients receiving whole brain radiotherapy (WBRT) today are treated with an immobilisation mask which fully covers their face and therefore might be experienced as uncomfortable and claustrophobic. In recent years, optical surface scanning (OSS) systems have been implemented for patient positioning and real-time motion monitoring [1]. READ MORE

2. Design and evaluation of a novel Transillumination SFDI system for quantitative assessment of tissuesections for rapid, label-free cancer margin detection
University essay from Linköpings universitet/Institutionen för medicinsk teknikAbstract : This study investigates the potential of Spatial Frequency Domain Imaging (SFDI) as a non-invasive imaging technique for tissue analysis in the context of Mohs surgery, a standard procedure for skin cancer removal with margin control. The current practice of performing multiple histopathologic sections during the procedure is time-consuming and labor-intensive. READ MORE

3. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.

4. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study
University essay from Linköpings universitet/Institutionen för medicinsk teknikAbstract : The objective of this preliminary study was to determine the potential of diffuse correlation spectroscopy (DCS) for assessment of coagulation depth. Coagulation of tissue can occur due to a number of different reasons such as thermal or electrical burns or radiofrequency ablation. READ MORE

5. Development and characterization of tissue-mimicking phantom materials for photoacoustic imaging
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. READ MORE
