HigHNoon - CT Guide

Why HigHNoon?

In interventional radiology, every millimeter matters. Even a small deviation in needle angle or entry point can require additional scans, increasing radiation exposure and patient discomfort.

HigHNoon changes that. It transforms CT-guided interventions using light- and shadow-based real-time needle navigation. A calibrated light and laser system projects a precise shadow and laser guidance pattern aligned with the planned needle trajectory. As the clinician positions the needle, the shadow provides instant visual feedback, ensuring accurate alignment with the planned path before puncture and during insertion.

No guesswork. No delays. Just smarter, faster, and safer interventions.

Three Key Pillars

Absolute Precision

Experience 2mm accuracy with real-time laser and shadow guidance. HigHNoon visually aligns every planned trajectory, ensuring the needle follows the exact CT-defined path — even in small, deep, or mobile targets.


Consistent Control

HigHNoon provides real-time visual guidance that keeps the planned trajectory aligned from entry to target—reducing variability and improving reproducibility. With fewer manipulations and rescans, procedures become faster, safer, and more consistent, while still preserving freehand flexibility.

Seamless Efficiency

HigHNoon integrates seamlessly with any existing CT workflows. Its plug-and-play design requires no repeated calibration, enabling quick setup and supporting multiple clinical applications without disrupting routine operations.


Clinical Benefits:

For interventional radiologists, HigHNoon simplifies complex needle-guided procedures and enhances operator confidence—even for deep-seated, small, or critically located targets.

It shortens the learning curve for interventional radiologists early in their practice, improves reproducibility across users, and enables faster procedures with greater precision.

For patients, it means:

  • Shorter time on the CT table
  • Less radiation exposure
  • Fewer punctures
  • Higher accuracy and comfort

    Patient-Centric Features

    Breathing Synchronization

    Even a small inhale or exhale can shift a lesion by millimeters. HigHNoon’s dynamic visual navigation helps radiologists synchronize insertion with the patient’s breathing, maintaining trajectory accuracy despite respiratory motion — reducing rescans and improving first-pass success.

    Patient Movement Detection

    Using reference markings and laser-based light-shadow alignment, HigHNoon detects even slight patient movement in real time. Instant visual feedback allows radiologists to correct trajectory shifts before they occur, enhancing both procedural safety and targeting precision.

    Clinical Applications:

    • Ablation
    • Biopsy
    • Drainage
    • Drug Delivery

    Efficacy of Shadow-Based Needle Positioning System in Performing CT Image-Guided Percutaneous Biopsy of Lung Lesions: Our Initial Experience

    Computed tomography (CT) plays a key role in interventions such as tumor ablation, FNAC/FNAB, percutaneous block of the upper sympathetic chain, treatment of secondary pulmonary aspergilloma, and brachytherapy. The procedures are user-dependent, and achieving accuracy is challenging. Several navigation tools have been innovated for CT-guided interventions; however, drawbacks continue to exist. There is a need for a navigation tool with improved accuracy and reduced intervention time.
