LabVIEW Graphical User Interface for a New High Sensitivity, High Resolution Micro-Angio-Fluoroscopic and ROI-CBCT...

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Radiology

Background:

• High-resolution imaging is crucial for visualizing small vessels and endovascular devices.
• Existing systems may lack the necessary real-time acquisition and display capabilities for detailed analysis.
• Clinical evaluation requires user-friendly interfaces for system control and image processing.

Purpose of the Study:

• To develop and evaluate a LabVIEW-based graphical user interface for a novel High-Sensitivity Micro-Angio-Fluoroscopic (HSMAF) system.
• To enable real-time acquisition, display, and rapid frame transfer of high-resolution images.
• To assess the system's utility for clinical applications in angiography and interventional procedures.

Main Methods:

• Development of a graphical user interface using LabVIEW software for controlling HSMAF system parameters.
• Integration of a CsI(Tl) phosphor, light image intensifier, and CCD camera for image acquisition.
• Implementation of features including synchronized acquisition, digital subtraction angiography (DSA), image processing, and playback.

Main Results:

• The HSMAF system achieves real-time 12-bit, 1k x 1k images with >10 lp/mm resolution at up to 30 fps.
• The LabVIEW interface provides control over camera modes, image acquisition, storage, display, and processing.
• The system supports advanced imaging techniques like roadmap and DSA, with capabilities for filtering and gain control.

Conclusions:

• The developed LabVIEW interface facilitates clinical evaluation of the HSMAF system.
• The high-resolution, high-frame-rate imaging capability offers a significant advancement for visualizing small vessels and devices.
• This technology has the potential to improve diagnostic accuracy and guide interventional procedures more effectively.
