System Components

Custom-Fit Probe Design

• Material: Utilizing advanced conductive polymers, the probe’s dome end is 3D printed to fit the unique anatomy of each patient precisely. This ensures optimal contact with the cervix, crucial for accurate EIT scanning.
• Manufacturing: Immediate, on-demand 3D printing of the dome end allows for quick customization based on a prior AI-powered sizing scan, ensuring a perfect fit and reducing preparation time for the screening procedure.

Electrical Impedance Tomography (EIT)

• Principle: EIT is a non-invasive imaging technique that measures the impedance of different tissues to electrical currents. Since cancerous tissues and healthy tissues have distinct electrical properties, EIT can highlight these differences, enabling the detection of abnormalities.
• Phased Array Technology: Integrating phased array engineering enhances the resolution and depth of EIT imaging. By dynamically adjusting the electrical fields, it’s possible to focus on specific areas of interest within the cervix, improving the detection of early-stage cancerous changes with unprecedented clarity.

Microfluidic Tip

• Functionality: A microfluidic tip integrated into the probe’s design allows for simultaneous biological sample collection during the EIT scan. This feature enables the collection of cellular material from the cervix, which can be used for further pathological analysis.
• Design: The tip is designed to extend through a central channel in the dome, allowing for precise targeting and minimal discomfort during sample collection.

Operational Workflow

1. Sizing and Customization: Initially, an AI-powered sizing probe is inserted to map the patient’s cervical anatomy. Data collected on dimensions and elasticity inform the design of the custom-fit dome, which is then 3D printed from conductive polymer material.
2. Screening Procedure: The custom-fit dome, attached to the main probe body, is gently inserted to achieve complete contact with the cervix. The phased array EIT system is activated, sending small electrical currents through the cervical tissue. Impedance measurements are captured and analyzed in real-time, generating a high-resolution map of the cervical area.
3. Sample Collection: Concurrently, the microfluidic tip collects biological samples from the cervix. This process is designed to be seamless and minimally invasive, with the capability to target specific areas identified by the EIT system as potentially abnormal.
4. Analysis and Diagnostics: The impedance data, along with the collected biological samples, are analyzed to identify any abnormalities. Advanced algorithms interpret the EIT data to distinguish between healthy and potentially cancerous tissues, while the biological samples undergo pathological examination for cellular abnormalities.
5. Result Interpretation and Follow-Up: Results from the EIT scan and pathological analysis provide a comprehensive diagnostic overview. Based on these findings, healthcare providers can recommend appropriate follow-up actions, ranging from routine monitoring to more targeted diagnostic procedures or treatments.

Advantages

• Precision and Accuracy: The integration of custom-fit probes with phased array EIT technology offers unprecedented precision in detecting cervical abnormalities, potentially identifying precancerous conditions and cancer at very early stages.
• Patient Comfort: The use of a custom-fit, 3D-printed probe end from conductive polymers significantly enhances patient comfort, reducing anxiety and discomfort associated with cervical screening.
• Safety and Hygiene: The disposable nature of the custom-fit dome end ensures a sterile procedure environment for each patient, minimizing the risk of cross-contamination.
• Comprehensive Diagnostics: By combining EIT imaging with microfluidic sample collection, the device provides a holistic view of cervical health, enabling more informed diagnostic decisions and treatment plans.

Conclusion

This advanced cervical screening device leverages cutting-edge technologies to offer a more accurate, comfortable, and safe alternative to traditional screening methods. By marrying the capabilities of conductive polymers, EIT, phased array technology, and microfluidics, it promises to transform cervical cancer diagnostics, paving the way for earlier detection and more effective treatment strategies.
