Why HigHNoon?

In any CT-guided intervention, the accuracy of needle placement, which influences diagnostic performance or treatment success, largely depends on the skill and experience of the physician.

With conventional techniques, challenging targets often require multiple needle adjustments and imaging during the procedure. This can prolong the procedure duration and increase patient discomfort, radiation exposure, and procedural risk.

  • Target Accuracy: 2 mm
  • Angular Error: -2.2°
  • Manipulations: 3%
     
     
  • Time Required for Needle Placement: 11 min.
  • Average Wheel Entry and Exit Time: 26 sec
  • Mean value calculated over data from 55 patients

  • Effectiveness of Shadow-Based Needle Positioning System for Image-Guided Percutaneous Biopsy of Lung Lesions by Computed Tomography: Our Initial Experience

    Pain Management:

    Computed Tomography (CT) plays a key role in interventions such as tumor ablation, FNAC/FNAB, percutaneous upper sympathetic chain block, treatment of secondary pulmonary aspergilloma, and brachytherapy. Procedures rely on the user, and achieving precision is a challenge. Several navigation tools have been innovated for CT-guided interventions; however, drawbacks still exist. There is a need for a navigation tool with higher precision and shorter intervention time.
