Solution Overview

Problem

Current methods for detecting pre-cancerous and cancerous tissue in the colon using X-Ray capsules are inefficient, as they often require extensive examination by trained experts and may overlook cancerous tissue due to limited imaging capabilities.

Innovation Solution

A system where a patient swallows a solution with nanoparticles coated to adhere to cancerous tissue, followed by an X-Ray capsule that emits radiation and detects energy levels to construct images highlighting the locations of nanoparticles, enhancing the visibility of cancerous polyps or tumors.

Function Achieved in This Case

This method improves the detection of cancerous tissue by clearly marking locations with high nanoparticle density, reducing the likelihood of overlooking small or flat polyps and providing a more accurate indication of tissue severity.

Implementation Method 1

a radiation source providing X-Ray and gamma radiation with energies sufficient to induce X-Ray fluorescence from nanoparticles that adhere to cancerous tissue

Methodology Applied
Scientific EffectX-Ray fluorescence: Fluorescence

Implementation Method 2

The imaging capsule typically includes a radiation source, for example including a radioisotope that emits X-rays and/or Gamma rays. The radiation is typically collimated to allow it to be controllably directed toward a specific area during the imaging process. In an exemplary case the imaging capsule is designed to measure X-Ray fluorescence and/or Compton back-scattering

Methodology Applied
