Endoscope Image Recording Apparatus Missing Still Image Alert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In endoscopic examinations, there is a risk of missing images due to incomplete manipulation of the still image shooting button or misjudgment by the operator, leading to incomplete data for diagnosis, and existing solutions require large-scale apparatus or extensive preparation.
Innovation Solution
An endoscope system with a number-of-images counting unit, comparing unit, and alert generating unit that counts and compares the number of still images taken with a preset number, generating an alert for missing images, and an endoscope image recording apparatus that assists in generating missing still images from moving image data to complete the still image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the operator manually takes still images during endoscopic examination, then the imaging process is simple and quick, but mistakes occur such as failure to image some parts to be examined
Solution Approach 1:
The system provides real-time feedback by comparing the number of still images taken with the preset number of examination parts. The number-of-images comparing unit continuously monitors whether the counted number of still images matches the expected number, and the alert generating unit notifies the operator when there is a mismatch, ensuring all examination parts are imaged.
Solution Approach 2:
The system automatically counts the number of still images taken and compares it with the preset number of examination parts without requiring manual tracking by the operator. The apparatus self-monitors the imaging process and self-notifies when incomplete imaging is detected.
2Measurement precision
If position detecting apparatus with magnetism generating units and magnetic sensors is used, then the position of insertion unit can be detected, but the apparatus becomes large-scale and complex
Solution Approach 1:
The patent extracts only the essential function of position detection from complex magnetic sensing systems. Instead of using magnetism generating units and magnetic sensors distributed throughout the examination bed, the system uses a simplified approach where the endoscope insertion unit itself provides position information through its controlled movement, and only the number of images taken is monitored to infer positioning status.
Solution Approach 2:
The system creates a simplified model of position detection by counting image acquisitions rather than directly measuring physical position. Each still image capture is treated as a proxy indicator that the insertion unit has reached a designated examination part, eliminating the need for complex physical sensing infrastructure.
3Reliability
If 3D image data is generated in advance by CT apparatus, then the insertion unit can be moved to desired position reliably, but extensive preparation is required
Solution Approach 1:
The system performs preliminary setup by storing the preset number of examination parts in the storage unit before the actual endoscopic examination. This preliminary configuration allows the number-of-images comparing unit to function during the procedure without requiring time-consuming 3D image generation or CT scanning beforehand.
Solution Approach 2:
Instead of generating complete 3D image data for the entire body cavity, the system uses a partial approach by only storing the essential information of how many images should be taken. This minimal preliminary action provides sufficient guidance for reliable imaging without the excessive preparation time required for full 3D reconstruction.
4Loss of information
If the number of still images taken is less than the preset number, then incomplete image data results, but re-imaging increases patient load
Solution Approach 1:
The system takes preliminary anti-action by detecting incomplete imaging during the examination procedure itself, not after. The alert generating unit notifies the operator of missing images while the endoscope is still in position, allowing immediate correction before patient removal, thereby preventing the need for re-examination and reducing patient burden.
Solution Approach 2:
The system provides immediate feedback when the number of still images taken does not match the preset number of examination parts. This real-time notification allows the operator to correct incomplete imaging during the same examination session, preventing information loss without requiring additional patient procedures.

AI summary
Plural predetermined examination parts of a patient are imaged sequentially and still images of the respective examination parts are thereby acquired by inserting an endoscope insertion unit having an imaging optical system in its tip portion into the body cavity of the patient. To this end, the number of still images taken is counted every time one of the predetermined examination parts. The counted number of still images taken is compared with a preset number of images which corresponds to the number of the plural predetermined examination parts. An alert is generated when non-coincidence is detected between the counted number of still images taken and the preset number. The operator is thus notified of occurrence of a failure to image.
