Summary
Smart Puncture, a smartphone app, accurately guides CT-guided punctures without fluoroscopy. This innovation enhances precision in medical procedures, offering a valuable tool for physicians.
Area of Science:
- Medical Imaging Technology
- Interventional Radiology
Background:
- Conventional computed tomography (CT)-guided punctures often rely on CT fluoroscopy.
- There is a need for accessible and precise guidance tools in interventional radiology.
Observation:
- A novel smartphone application, "Smart Puncture," was developed to aid CT-guided punctures.
- The app utilizes motion sensors and LCD angle detection to display accurate puncture guidelines.
- Experimental testing involved puncturing a sponge target at various angles and device tilts.
Findings:
- The application demonstrated mean puncture errors of less than 2° parallel to the LCD, regardless of device tilt.
- Errors in the sagittal plane were less than 3° without device tilt but increased with tilt.
- The "Smart Puncture" app objectively and accurately assists CT-guided procedures.
Implications:
- This technology can potentially reduce reliance on CT fluoroscopy for certain puncture procedures.
- Smartphones can be transformed into valuable tools for enhancing accuracy in medical interventions.
- The application offers a cost-effective and accessible solution for improving CT-guided puncture accuracy.
