Radial Artery Model For Catheterization Procedures, Kyla Beville, Mitchell Gagnon, Benjamin Stalls, Maya Ariza
Williams Honors College, Honors Research Projects
The purpose of this project was to create a radial artery model that is usable under ultrasound that would reduce complications during catheterization procedures. Each year, over one million of these procedures are done and complications can affect the outcomes of the patient. Using ultrasound during these procedures is an upcoming way to reduce these complications and improve the outcome that a patient will have.

A 3d Us Guidance System For Permanent Breast Seed Implantation: Development And Validation, Justin Michael
A 3d Us Guidance System For Permanent Breast Seed Implantation: Development And Validation, Justin Michael
Electronic Thesis and Dissertation Repository
Permanent breast seed implantation (PBSI) is a promising breast radiotherapy technique that suffers from operator dependence. We propose and have developed an intraoperative 3D ultrasound (US) guidance system for PBSI.
A tracking arm mounted to a 3D US scanner registers a needle template to the image. Images were validated for linear and volumetric accuracy, and image quality in a volunteer. The tracking arm was calibrated, and the 3D image registered to the scanner. Tracked and imaged needle positions were compared to assess accuracy and a patient-specific phantom procedure guided with the system.
Median/mean linear and volumetric error was ±1.1% and …
Neurosurgical Ultrasound Pose Estimation Using Image-Based Registration And Sensor Fusion - A Feasibility Study, Utsav Pardasani
Neurosurgical Ultrasound Pose Estimation Using Image-Based Registration And Sensor Fusion - A Feasibility Study, Utsav Pardasani
Electronic Thesis and Dissertation Repository
Modern neurosurgical procedures often rely on computer-assisted real-time guidance using multiple medical imaging modalities. State-of-the-art commercial products enable the fusion of pre-operative with intra-operative images (e.g., magnetic resonance [MR] with ultrasound [US] images), as well as the on-screen visualization of procedures in progress. In so doing, US images can be employed as a template to which pre-operative images can be registered, to correct for anatomical changes, to provide live-image feedback, and consequently to improve confidence when making resection margin decisions near eloquent regions during tumour surgery.
In spite of the potential for tracked ultrasound to improve many neurosurgical procedures, it …

A Novel Imaging System For Automatic Real-Time 3d Patient-Specific Knee Model Reconstruction Using Ultrasound Rf Data, Rimon Adel Messiha Tadross
A Novel Imaging System For Automatic Real-Time 3d Patient-Specific Knee Model Reconstruction Using Ultrasound Rf Data, Rimon Adel Messiha Tadross
Doctoral Dissertations
This dissertation introduces a novel imaging method and system for automatic real-time 3D patient-specific knee model reconstruction using ultrasound RF data. The developed method uses ultrasound to transcutaneously digitize a point cloud representing the bone’s surface. This point cloud is then used to reconstruct 3D bone model using deformable models method.
In this work, three systems were developed for 3D knee bone model reconstruction using ultrasound RF data. The first system uses tracked single-element ultrasound transducer, and was experimented on 12 knee phantoms. An average reconstruction accuracy of 0.98 mm was obtained. The second system was developed using an ultrasound …
