Latest Patents

Alex Stewart holds a patent for a "Tomosynthesis imaging system and method." This system is designed for three-dimensional tomosynthesis imaging of a target element. It includes an image acquisition element and a processor. The image acquisition element captures multiple images of the target element from various angles, utilizing a radiation source that can be positioned at different angles relative to the target element, along with a radiation detector. The radiation detector is strategically placed to detect radiation emitted by the source as it passes through the target element. This setup allows for the determination of multiple attenuation values, which are essential for creating a radiation absorbance projection image of the target element for a specific radiation source angle. The processor then applies an iterative reconstruction algorithm to these images, generating a comprehensive three-dimensional reconstruction of the target element.
