A light-guidance system to be used for CT-guided biopsy

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Surgical Navigation

Background:

• CT-guided biopsies are crucial for diagnosing chest and abdominal conditions.
• Accurate needle placement is essential for effective and safe biopsy procedures.
• Current guidance methods can be limited in complex anatomical regions or with compound angles.

Purpose of the Study:

• To introduce a new light-guidance system for CT-guided biopsies.
• To enable precise guidance for biopsy approaches from any direction, including compound angles.
• To enhance visualization and simplify the setup of biopsy apparatus.

Main Methods:

• Utilized intersecting helium-neon laser beams to create a guidance system.
• Developed interactive software for path visualization and trajectory planning.
• Integrated apparatus setting display for user convenience.

Main Results:

• The system provides precise guidance for biopsy approaches.
• It accommodates approaches from any direction, including compound angles.
• Interactive software effectively visualizes proposed paths and relevant settings.

Conclusions:

• The described light-guidance system offers a precise and versatile solution for CT-guided biopsies.
• This technology has the potential to improve accuracy and efficiency in chest and abdominal interventions.
• Interactive software enhances usability and planning for clinicians.
