Research Title: Dual-Energy Computed Tomography Temperature Monitoring
Synopsis: My primary focus is the use of
Dual-Energy Computed Tomography (DECT) to assess temperature changes
in tissue.
Temperature monitoring is particularly important for thermal therapies of malignant disease to ensure treatment of the whole tumor volume, while minimizing damage to the normal tissues surrounding the lesion. I am currently performing preliminary experiments to assess the sensitivity of DECT metrics to changes in the thermal expansion of water and various tissue types and assessing the reproducibility of CT temperature measurements.

Research Title: Measurement of MR brain connectomics in glioma patients
Synopsis: Dr. Chen’s research focuses on the use of advanced MRI for surgical planning and outcome prediction of brain tumor resection. His current project aims to develop MR measurement methods to build a predictive model that simulates the impact of neurosurgery on both functional and structural brain connectomics by utilizing pre-operative imaging.
The goals of the model are twofold: 1) to provide a basis for predicting near- and long-term patient outcome, and 2) to use these predictions in a real-time environment to optimize the surgical plan to the individual patient.

Research Title: Constrained Reconstruction Methods
Synopsis: As a member of the magnetic relaxometry research lab, I have the opportunity to work with a novel technology that estimates the location of target-biology using nanoparticles (MRXTM). My efforts primarily focus on utilizing convex optimization algorithms to model and constrain the acquired signal from the nanoparticles to generate a distribution map with high sensitivity.

Research Title:: Optimization of Data-Driven Gated PET/CT
Synopsis: Data-driven gated (DDG) PET/CT aims to improve motion correction and misregistration in PET/CT. DDG PET has been studied for several years and recently became commercially available through GE. DDG CT is a much newer area where the same benefits of motion correction and respiratory phase binning from 4D-CT can be achieved without an external motion device. DDG PET/CT corrects both PET and CT for respiratory motion, enabling ideally matched PET and CT data for registration and optimal attenuation correction. DDG PET/CT will offer the same improvements to PET/CT imaging as 4D-CT and 4D-PET but without the need for any external device setups. Our current DDG CT technique utilizes the same cine CT protocol used for 4D-CT and average CT, both of which have been used in routine clinical practice for thousands of radiation therapy (4D-CT and average CT) and cardiac PET/CT (average CT) patients.
Our goal is to maximize the potential clinical benefits of DDG PET by improving and/or fine-tuning DDG CT methods that have only recently been explored in research or through early-stage commercial development (GE). The primary objective is to offer DDG PET/CT both prospectively and retrospectively for all PET/CT studies and patients without the need for external motion device tracking and setup.

Research Title: Functional Sequelae of Variable Radiation Dose Exposure to Netowrk Hubs in Brain Connectomes
Synopsis: Dr. Mitchell's research focuses on the use of brain connectomic measurements as a novel predictor of neurocognitive function (NCF) impairment caused by radiation therapy. The goals of this work are 1) to determine the associations between radiation-induced NCF impairments and radiation dose distribution to network hubs in patients with head and neck/base of skull tumors and 2) to build a hub-based radiation-injury model to simulate post-radiation brain connectomes for the prediction of radiation-induced NCF impairments.

Research Title: Development and implementation of MRI and image analysis techniques for MRI-assisted radiosurgery (MARS) of prostate cancer
Synopsis: Dr. Sanders’ research focuses on developing new MRI and image analysis techniques for MARS low-dose-rate (LDR) prostate brachytherapy, a curative radiotherapy treatment for prostate cancer. The goals are to reduce the technical barriers for using MRI in LDRPBT and to improve the consistency and quality of this curative radiotherapy treatment through the development and translation of advanced MRI and image processing techniques. We are also investigating the effectiveness and limitations of machine learning (ML) and deep learning (DL) techniques in clinical imaging applications including cancer detection, target and organs at risk segmentation, and image synthesis.
Our MRI research focuses on developing the imaging capability of a multimodality implantable fiducial marker for prostate radiotherapy treatments. The goal is to enable imaging of it across X-ray CT, kV linear accelerator imaging, and MRI for patients receiving multimodality radiotherapy treatments. Our image analysis research focuses on developing decision support systems to assist with treatment planning and treatment quality assessment of MARS LDR prostate brachytherapy.

Research Advisor: James A. Bankson Ph.D.
Research Title: Development and Optimization of Imaging Methods for Hyperpolarized MRI
Synopsis: Hyperpolarized (HP) MRI is an emerging modality that enables non-invasive interrogation of cells and tissues with unprecedented biochemical detail. Due to the highly transient nature of HP signals, specialized methods are needed for acquiring and analyzing imaging data in order to extract accurate and reproducible measurements of tissue function. In clinical imaging of cancer and other diseases, these measurements of perfusion and metabolism hold tremendous potential in the rapid assessment of disease state and evaluation of early treatment response.
Our goals in this work are the development and validation of imaging
strategies that provide improved quantitative biomarkers of perfusion
and metabolism, for example via greater insight into the physiological
compartmentalization of HP signals in vivo. Such improvements in
biomarkers derived from HP imaging data will be vital in establishing
the value of HP MRI for clinical use.
