For radiologist Hou Dailun, artificial intelligence has made a major difference in his daily work.
Hou, head of Beijing Chest Hospital's medical imaging department, said since the introduction of an AI system in 2020, he's witnessed a significant improvement in the accuracy and efficiency of the department's work.
The system assists radiologists in analyzing the results of computed tomography scans for lung nodules.
After several years of refinement, the system is now able to analyze "within seconds" a CT scan of a person's lung, which often contains 300 to 600 slices, and provide accurate information on the size, shape and density of nodules, Hou said.
Radiologists further evaluate the system's initial findings and come up with suggestions on whether surgery is needed.
Before the system was put to use, Hou said it used to take him more than 20 minutes to go through all of a patient's CT lung scan slices.
With the help of the system, the department is able to complete the interpretation of lung nodule CT scan results for about 600 patients a day, he said.
