[A study on computer assistant real-time diagnosis for micro-focused lesion of esophagus]
1The Digestive Endoscopic Center, West China Hospital, Sichuan University, Chengdu 610041, China.
Objective:
To investigate the effect of computer-assisted real-time diagnosis on esophagus micro-focused lesion based on the change of grey shade.
Methods:
Comparison algorithm for the hue saturation mean value and integral algorithm for the vibration frequency of grey color shade were used to analyze the esophagus images collected by quick and real-time operation.
Results:
The research results showed that, the image-operative software, based on the two kinds of arithmetic mentioned above, had some effects on discriminating the esophagus micro-focused lesions, such as esophagitis, early carcinoma of esophagus, middle-late carcinoma of esophagus and atypical hyperplasia of esophagus one another.
Conclusion:
The software could be used as a kind of assisted diagnostic measure to screen out the micro-focused lesion of esophagus effectively.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
