Augmented Reality Training Platform for Placement of Neurosurgical Burr Holes
Baum, ZacAugmented reality has been used in neurosurgery to aid in the visualization of lesions, though it has not been widely adopted for simulation-based neurosurgical training. This work aims to determine if augmented reality ... -
Breast Reconstruction Planning and Assessment Using Three-Dimensional Surface Scans
House, RachaelPurpose: Breast-conserving therapy can result in significant breast deformity in up to 40 percent of patients. Breast reconstruction to correct these deformities is considered an integral part of breast cancer care. ... -
Characterization of Ultrasound Elevation Beamwidth Artefacts for Brachytherapy Needle Insertion
Peikari, Mohammad (2011-09-01)Ultrasound elevation beamwidth is the out of plane thickness causing image artefacts normally appearing around anechoic areas in the medium. These artefacts could also cause uncertainties in localizing objects (such as ... -
A cloud-based system for measuring radiation treatment plan similarity
Andrea, Jennifer (2016-09-27)PURPOSE: Radiation therapy is used to treat cancer using carefully designed plans that maximize the radiation dose delivered to the target and minimize damage to healthy tissue, with the dose administered over multiple ... -
Computer-assisted Assessment and Feedback for Image-guided Interventions Training
Holden, MatthewTo improve patient safety, many surgical and interventional specialties use simulation training. This ensures that trainees have a minimum level of proficiency prior to real patient encounters. During simulation training, ... -
Computer-assisted Workflow Recognition for Central Venous Catheterization
Hisey, RebeccaPurpose: The transition to competency-based medical education from an apprenticeship model requires a greater amount of human resources to evaluate trainees. Therefore, there is an increased need for tools that can evaluate ... -
Computer-Integrated Methods for Breast Cancer Surgery and Brachytherapy Guidance
Vaughan, ThomasBreast cancer is a leading cause of cancer-related death in women in Canada. Lumpectomy and brachytherapy are treatments of choice for early stage breast cancer, but the soft nature of the breast makes it difficult to ... -
Data Management Workflow and Architecture For Simulation-Based Medical Training
Abou-Seido, Nisrin (2015-09-01)Purpose: Research is ongoing on how best to integrate simulation-based surgical training and the associated quantitative metrics into competency-based medical education. In a review of the literature, study data management ... -
Development of a Computational Treatment Planning System for Radiofrequency Ablation of Vertebral Metastases
Underwood, GraceIntroduction: Vertebral metastases affect around 61,000 Americans annually. The presence of vertebral metastases may lead to skeletal related events which can include pain, fracture, and neurologic compromise, all of which ... -
Dynamic Representation of Anatomical Structures in Radiation Therapy Treatment Planning and Evaluation
Pinter, CsabaSegmentation is a ubiquitous operation in radiation therapy (RT) and in medical image computing (MIC) in general. Various data representations can describe segmentation results, such as binary volumes or surface models. ... -
Electromagnetic tracking in ultrasound-guided high dose rate prostate brachytherapy
Lugez, Elodie (2016-03-22)Electromagnetic (EM) tracking assistance for ultrasound-guided high-dose-rate (HDR) prostate brachytherapy has recently been introduced in order to enable prompt and uncomplicated reconstruction of catheter paths with ... -
Fractional Labelmap Representation of Anatomical Structures
Sunderland, KyleINTRODUCTION: In medical imaging software, structures are often represented using image volumes known as labelmaps. Conversion of structures to labelmap representations results in a loss of information which impacts medical ... -
An immersive virtual reality environment for diagnostic imaging
King, Franklin (2015-08-26)Advancements in and adoption of consumer virtual reality are currently being propelled by numerous upcoming devices such as the Oculus Rift. Although applications are currently growing around the entertainment field, ... -
Immobilization and Catheter Guidance for Breast Brachytherapy Using Patient-Specific Templates
Pompeu-Robinson, Alexandra (2011-10-03)Brachytherapy is an important method of breast cancer treatment; however, improvements in both treatment planning and delivery are needed. The procedure involves insertion of catheters in the tumor site, which, in current ... -
Linear Object Registration for Image-Guided Interventions
Holden, Matthew (2014-08-25)Purpose: Image-guided interventions rely on registration of images, models, and surgical tools into a common navigation space. Point-set registration is commonly used to perform this registration, but requires well-defined ... -
Point-Based Registration of Brachytherapy Implants
Gordon, Lauren Elizabeth (2012-01-04)Prostate brachytherapy, a treatment for prostate cancer, was a procedure that typically involved placing radioactive sources in a cancerous prostate using percutaneous needles. The placement of these sources determined ... -
Scoliosis visualization using ultrasound data
Church, BenScoliosis is a disease characterized by spinal deformation which typically appears during adolescence and growth. Regular assessment to monitor the progression of the disease is important to ensure timely intervention. ... -
Software for Designing Custom Orbital-Craniofacial Implant Plans
Ibrahim, AmaniPurpose: Custom cranio-orbital implants have been shown to achieve better performance than their hand-shaped counterparts by restoring skull anatomy more accurately and by reducing surgery time. Designing a custom implant ... -
Surface Mesh-Based Ultrasound Simulator For Spinal Interventions
Bartha, Laura (2013-07-24)Purpose: Ultrasound is prevalent in image-guided therapy as a safe, inexpensive, and widely available imaging modality. However, extensive training in interpreting ultrasound images is essential for successful procedures. ... -
Target localization in MRI-guided prostate biopsy
