New Developments on Quantitative Imaging Using Ultrasonic Waves
Although ultrasound imaging is widely used for medical applications, conventional sonographic B-mode images are qualitative. As a consequence, medical diagnosis using sonograms is commonly subjective and depends on the expertise of the operator. The need to obtain quantitative information from …

Statistical Preconditioning and Quantitative Imaging for Electrical Impedance Tomography
… As x-ray mammography is the current standard imaging modality used to screen for breast cancer, it is natural to see if we can combine the high spatial resolution of the mammogram image along with the EIT solution to improve the sensitivity and specificity of the diagnosis, rather than using …

Quantitative imaging of living cells by deep ultraviolet microscopy
… yet many questions remain unanswered by current imaging approaches. Deep ultraviolet microscopy received attention in the 1950s as a way to generate image contrast from the strong absorbance of proteins and nucleic acids at wavelengths shorter than 300 nm. However, the lethal effects of these …

Quantitative Imaging For Precision Medicine In Head and Neck Cancer Patients
… work was to determine if prediction models using quantitative imaging measures in head and neck squamous cell carcinoma (HNSCC) patients could be improved when noise due to imaging was reduced. This was investigated separately for salivary gland function using dynamic contrast enhanced magnetic …

Statistical Methods For The Analysis And Development Of Quantitative Imaging Biomarkers
The field of neuroimaging statistics is concerned with elucidating meaningful conclusions from high-dimensional imaging objects, often in the form of single-dimensioned summary statistics. Ideally, these summaries should provide interpretable biomarker measurements that can guide patient diagnoses …

Towards real-time light field processing for quantitative imaging and perception
This thesis aims to make light field imaging based 3D particle image velocimetry (PIV) practically feasible and affordable. In addition, this thesis also extends light field imaging techniques developed with PIV as a target application, for improved perception in robotics. Building upon the basic …

Integrating Serial Quantitative Imaging with Clinical Data to Predict Brain Hemorrhage Outcomes
Serial brain imaging, particularly non-contrast computed tomography (NCCT), is routinely used to diagnose, monitor, and inform clinical decisions in patients with brain hemorrhage. Subarachnoid hemorrhage (SAH) is a devastating form of brain hemorrhage in which blood erupts into the space …

Development of a method for quantitative imaging of air-water gas exchange
… could be used to obtain horizontally resolved, quantitative information on local changes in the concentration of a dissolved gas in the water-side mass boundary layer for the first time. During the experiments, also a fluorescence profile created by a focused laser beam was imaged at 800 Hz by a …

Engineering semiconductor quantum dots for quantitative imaging of cell motility and invasion
… makes them useful for a variety of biological imaging applications. In this study, QDs presenting different chemical moieties were used to quantify non-specific binding to different extracellular matrix (ECM) proteins. QDs coated with poly-maleic anhydride (PMA), which had been modified to …

Non-contact quantitative imaging of limbs, bone and tissue, using ultrasound tomographic techniques
Non-contact and quantitative ultrasound images of bone and soft tissue are produced from original algorithms applied to observational data sets collected on two custom built ultrasound imaging systems for limb imaging. The images are quantitative in that the distribution of sound speeds and …

Quantitative imaging of the air-water flow fields formed by unsteady breaking waves
… and comparisons are drawn where applicable. Quantitative experimental data for the air flow induced by wave breaking in the absence of wind has not previously been observed, to the author's knowledge. Revealing physical insights and observations are drawn from this novel data.

Methodological Development of A Multi-Parametric Quantitative Imaging Biomarker Framework For Assessing Treatment Response With Mri
<p>Quantitative imaging biomarkers (QIBs) are increasingly being incorporated into early phase clinical trials as a means of non-invasively assessing the spatially heterogeneous treatment response to anticancer therapies, particularly as indicators for early response. MR QIBs are derived from the …

Photophysical characterization of toluene and 3 pentanone for quantitative imaging of fuel/air ratio and temperature in combustion systems
… tool in modern engine research. However, quantitative interpretation of fluorescence signals in terms of fuel/air ratio or temperature requires sound fundamental knowledge of the compound’s photophysical behavior, i.e. the dependence of the LIF-signal on temperature, pressure and bath gas …

Single-shot quantitative interferometric microscopy for imaging high-speed dynamics
… next-generation clinical diagnosis methods. For imaging these high-speed dynamics, we need optical microscopy methods having millisecond temporal resolution, submicron spatial resolution and the capability of quantitative imaging. However, current imaging techniques usually either could only …

Quantitative Non-Contrast Perfusion Measurements Using Arterial Spin Labeled MRI: Evaluation of Therapy Response in Brain Tumors and Technical Advancements in Kidneys
… any significant change in size becomes evident. Quantitative imaging techniques can identify these early effects, providing a valuable window of opportunity to effectively manage cancer treatments. Notably, angiogenesis, a key biological process that promotes aberrant tumor neovascularization, is …

Three-Dimensional Single-Molecule Localisation Microscopy and Visualisation Techniques
Quantitative imaging in complex biological samples requires techniques such as, super-resolution (SR) imaging to better understand the morphology and stoichiometry of proteins below the diffraction limit. 3 Dimensional (3D) SR tools such as the 3D double helix-point spread function (DH-PSF) and 3D …

Magnetization Transfer and Diffusion Tensor Imaging in Dogs with Intervertebral Disc Herniation
Background: Quantitative imaging surrogates of myelin and axonal integrity using magnetization transfer and diffusion tensor imaging may provide beneficial prognostic details on long-term post-surgical recovery in dogs with spinal cord injury (SCI) secondary to intervertebral disc herniation …
