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

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Chen Xu; [2019]
    Keywords : Physics and Astronomy;

    Abstract : 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

  2. 2. Measuring the Optical Properties of Human Muscle Tissue using Time-of-Flight Spectroscopy in the Near Infrared

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Staffan Strömblad; [2015]
    Keywords : photon; Time-of-Flight; muscle tissue; optical; spectra; Infrared; Physics and Astronomy; Technology and Engineering;

    Abstract : Optical spectroscopy is commonly used in technology and science today. The presence and concentration of a substance can be determined by its spectral signature, the typical wavelengths that are absorbed (or emitted) by the atoms or molecules. READ MORE

  3. 3. Broadband Photon Time-of-Flight Spectroscopy on Pharmaceutical Tablets and Dairy Products

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Sören Johansson; [2015]
    Keywords : Compositional Analysis; Dairy; Tablets; Pharmaceutics; Scattering; Absorption; Spectroscopy; Photonics; Optics; Chemometrics; Partial Least Squares; PLS; Physics and Astronomy;

    Abstract : In this thesis, Photon Time-of-Flight Spectroscopy (PTOFS) is presented as a method to measure absorption and scattering spectra of turbid media samples in the near infra red wavelength range. In particular, absorption and scattering spectra measured on pharmaceutical tablets and dairy products are used to analyse the composition of the samples. READ MORE

  4. 4. Photon time-of-flight and continuous-wave near-infrared-spectroscopy of human skeletal muscle tissue; a comparative study

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Matematisk fysik

    Author : Alfi Shaharin; [2013]
    Keywords : Photon time-of-flight spectrometer; pTOFS; Tissue Saturation; StO2; and CW-NIRS; Physics and Astronomy;

    Abstract : The focus of this thesis is to perform a comparative study between two noninvasive optical techniques: Photon Time-of-flight Spectroscopy (pTOFS) and a Continuous-wave NIRS system for measuring muscle tissue oxygen saturation. INVOS 5100C (Manufactured in 2011, Serial Number 11-10269, Produced by Somanetics Troy, MI 48084 USA) is such a CW-NIRS system that provides tissue oxygenation using continuous wave Near Infrared Spectroscopy technique and widely used in the hospitals.
