Innovation Summary:
This invention introduces a linear scanning architecture for computed tomography (CT) that eliminates the need for rotational gantries. The system uses linearly translating X-ray sources and detectors moving in opposite or near-opposite directions. This arrangement enables tomographic imaging in environments where traditional circular CT systems are impractical due to space, mobility, or cost constraints. The linear geometry is compatible with compressive sensing techniques, which allow for image reconstruction from sparse or limited-angle data. This reduces the amount of required projection data, enabling faster scans and lower radiation doses. The innovation supports modular designs and can be integrated into portable or in-line inspection tools. Its simplicity also lowers mechanical complexity, making it more reliable and easier to maintain. This linear CT approach represents a major step toward adaptable, point-of-care, or embedded diagnostic imaging systems.
Challenges / Opportunities:
Conventional CT scanners are large, mechanically complex, and require a fixed installation space. This restricts their use in emergency medicine, remote environments, and industrial settings. Moreover, their cost and complexity pose a barrier to widespread adoption in smaller clinics and developing regions. This invention solves these problems by eliminating the rotary gantry, reducing weight, complexity, and power requirements. It opens up new opportunities for mobile CT scanners, compact diagnostic tools, and cost-effective healthcare solutions. In industrial contexts, it offers flexible options for in-line inspection and quality control where space is limited.
