C11894: 3D Imaging Endoscope Method and Software
Novelty:
Inventors at Hopkins have developed a safer method for determining the diameter of an airway, specifically for stenosis, the abnormal narrowing of the airway.
Value Proposition:
The problem of stenosis, or abnormal narrowing of the airway is an upper airway anomaly that presents frequently in children and has significant associated morbidity. Current methods use Computed Tomography and Endotracial tubes for sizing has associated negative effects. This method and software system, called quantitative endoscopy (QE) is designed to replace current methods for determining airway diameter. Other advantages of the technology are:
- 3D Structure of the anatomy using the computed endoscope motion, triangulated salient, and image intensities.
- Recovery of motion scale using an external tracking system.
- Clinically useful mechanical sizing of the airways.
Technical Details:
Johns Hopkins researchers have developed a system and process for automatically determining the area and volume of the structures of non-collapsed tubular cavities. The method uses video sequences taken during video assisted endoscopy and performs the following steps. The images are used in the sequence to estimate the motion of the endoscope in the airway. An external tracking device is used to determine the correct scale of the endoscope motion. The measured motion of the endoscope is used to determine the structure of the biological tissue with respect to the endoscope position. Computing a 3D surface which represents the volume of the anatomy is the main feature.
Looking for Partners:
To develop and commercialize the technology to be used medically for measurement and diagnosis of any non-collapsed tubular cavity.
