  1. 1. Design and evaluation of a novel Transillumination SFDI system for quantitative assessment of tissuesections for rapid, label-free cancer margin detection

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Merel Younan; [2023]
    Nyckelord :SFDI; transillumination SFDI system; tissue-conserving surgeries; thin layers; tissue analysis; skin cancer;

    Sammanfattning : 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. LÄS MER

  3. 2. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Måns Boll; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 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. 3. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Zeyneb Alsadi; [2019]
    Nyckelord :DCS; Diffuse correlation spectroscopy; Biomedical optics; coagulation; phantom study; coagulation depth; coagulation thickness; diffusion; model; two layer model;

    Sammanfattning : 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. LÄS MER

  5. 4. Development and characterization of tissue-mimicking phantom materials for photoacoustic imaging

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Chen Xu; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : 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. LÄS MER

  7. 5. Preparation of Materials for Deep Tissue Imaging with Slow Light

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Mengqiao di; [2018]
    Nyckelord :Ultrasound Optical Tomography; Deep Tissue Imaging; Monte Carlo Simulation; Spectral Hole Burning; Physics and Astronomy;

    Sammanfattning : Ultrasound Optical Tomography (UOT) is a proposed technique, which combines ultrasound imaging and optical imaging in a new way to detect, e.g. LÄS MER
