Publications
Positive Force Feedback May Ameliorate Muscle Weakness

Performance Assessment of Texture Reproduction in High-Resolution CT
Assessment of computed tomography (CT) images can be complex due to a number of dependencies that affect system performance. In particular, it is well-known that noise in CT is object-dependent. Such object-dependence can be more pronounced and extend to resolution and image textures with the increasing adoption of model-based reconstruction and processing with machine learning methods. Moreover, such processing is often inherently nonlinear complicating assessments with simple measures of spatial resolution, etc. Similarly, recent advances in CT system design have attempted to improve fine resolution details - e.g., with newer detectors, smaller focal spots, etc. Recognizing these trends, there is a greater need for imaging assessment that are considering specific features of interest that can be placed within an anthropomorphic phantom for realistic emulation and evaluation. In this work, we devise a methodology for 3D-printing phantom inserts using procedural texture generation for evaluation of performance of high-resolution CT systems. Accurate representations of texture have previously been a hindrance to adoption of processing methods like model-based reconstruction, and texture serves as an important diagnostic feature (e.g. heterogeneity of lesions is a marker for malignancy). We consider the ability of different systems to reproduce various textures (as a function of the intrinsic feature sizes of the texture), comparing microCT, cone-beam CT, and diagnostic CT using normal- and high-resolution modes. We expect that this general methodology will provide a pathway for repeatable and robust assessments of different imaging systems and processing methods.

Building Scalable and Automated Verification Tools for Healthcare Imaging Systems
Traditional verification of healthcare imaging systems remains burdened by manual effort, fragmented vendor implementations, and limited traceability. Ensuring compliance with DICOM conformance statements across interacting components often requires testers to repeat labour-intensive checks across multiple systems, configurations, and protocol variants. As standards evolve and legacy infrastructures are retired, these activities struggle to keep pace with modern release cycles and become increasingly unsustainable, error-prone, and difficult to scale. This paper presents a human-centered automation framework that modernizes healthcare imaging verification through a unified pipeline of automated tools spanning key software subsystems. The framework abstracts underlying tool complexity and enables engineers and QA professionals to collaboratively execute, monitor, and interpret verification tasks. Guided by human-factor design principles, the approach lowers cognitive overhead, streamlines reporting, and improves transparency through repeatable workflows and traceable verification artifacts. The result is a scalable, adaptive, and user-friendly verification process that bridges standards-driven compliance with modern software engineering practices.

Verifying performance and safety is critical, but has been a bottleneck in the medical software release process. UI software testing, being the most complex and integrated component, has traditionally been tested manually. Because the UI software is constantly updated, building automated UI testing solutions (TAS) for continuous verification offers significant benefits — reducing manual labor and human errors, enabling early detection of software issues, and strengthening the robustness of the development lifecycle.
This presentation introduces a **readable and maintainable Python-based automation framework** for medical imaging applications that emulates user interactions, communicates with external web APIs, performs data validation, records test evidence, and generates comprehensive test reports.
