Abstract: A needle guiding device for imaging-guided procedures features sensors to monitor the needle's attitude and a calibration tool fixed to the imaging machine for alignment. The device offers customizable feedback, including visual, audible, and haptic alerts, to maintain the planned insertion trajectory. The calibration tool, which may include reference surfaces that are perpendicular, non-perpendicular, or feature a groove, ensures accurate alignment. The device can log procedural data and is compatible with both single-use and reusable configurations. It is designed for use with one needle at a time, with options to use multiple devices for multiple needles or sequentially against different needles.

Abstract: The invention provides an optical image processing system that performs convolutional operations using spatially modulated light and a photosensitive film embedded with a convolutional kernel. A spatial light modulator (101), such as a digital micromirror device or LCD panel, emits light corresponding to an input image. This light passes through a photosensitive film (102) embedded with the kernel via a process of photographic exposure, chemical development, and fixing. The modulated light is projected onto an output plane (103), forming the final image, which is the convolution of the input image and the kernel. This image can be captured by a camera for further analysis. The system allows real-time, high-speed image processing by utilizing the properties of light, reducing digital computational requirements, and enabling flexibility through replaceable films for various tasks.
