Implementation of digital multiplexing for high resolution X-ray detector arrays.

Area of Science:

• Medical Imaging
• Detector Technology
• X-ray Imaging

Background:

• X-ray imaging systems require larger fields of view (FOV) and high-resolution capabilities for regions-of-interest (ROI).
• Existing technologies face limitations in achieving both extended FOV and ROI high-resolution imaging simultaneously.

Purpose of the Study:

• To introduce and demonstrate the novel Multiple Module Multiplexer (MMMIC) for a 2x2 array of electron multiplying charge coupled device (EMCCD) based x-ray detectors.
• To enable extensible FOV and high-resolution ROI imaging in x-ray detection systems.

Main Methods:

• A two-stage configuration using three identical MMMICs was implemented to acquire and multiplex data from a 2x2 array of EMCCD detectors.
• The first stage utilized two MMMICs, each handling data from two EMCCD detectors.
• The second stage employed a single MMMIC to receive multiplexed data from the first stage, producing final 12-bit multiplexed data from all four modules.

Main Results:

• Successful acquisition and multiplexing of data from a 2x2 array of EMCCD detectors were achieved using the described MMMIC configuration.
• The system demonstrated the capability for both extended FOV and high-resolution ROI imaging.
• Final 12-bit multiplexed data was transmitted via a high-speed Camera Link interface.

Conclusions:

• The novel MMMIC effectively addresses the need for extensible FOV and high-resolution ROI imaging in EMCCD-based x-ray detector arrays.
• The demonstrated two-stage configuration successfully multiplexes data from multiple detectors, validating the MMMIC's potential for advanced x-ray imaging applications.
