Abstract: Disclosed is a method of auditing of artificial intelligence-based medical image enhancement, including: performing preprocessing to generate a comparison image based on an input image and an output image received from a medical image enhancement device; generating a heatmap image to generate a hallucination heatmap image including a hallucination region in the comparison image by inputting the comparison image to a deep learning model trained in advance; calculating an error risk to calculate a hallucination risk for the hallucination region based on pixel values of the hallucination heatmap image; and providing auditing information to provide the auditing information for auditing accuracy of the output image based on the calculated hallucination risk to a user.

Abstract: Disclosed are an optimization method and system for a personalized contrast test based on deep learning, in which a contrast medium optimized for each individual patient is injected to implement optimum pharmacokinetic characteristics in a process of acquiring a medical image, the method including: obtaining drug information of a contrast medium and body information of a patient, in a contrast enhanced computed tomography (CT) scan; generating injection information of the drug to be injected into the patient by a predefined algorithm based on the drug information and the body information; injecting the drug into the patient based on the injection information, and acquiring a medical image by scanning the patient; and amplifying a contrast component in the medical image by inputting the medical image to a deep learning model trained in advance.

Abstract: Provided is a deep learning based accelerated MRI image quality restoring method. The deep learning based accelerated MRI image quality restoring method includes extracting test information from an input accelerated MRI image, selecting at least one deep learning model corresponding to the test information, among a plurality of previously trained deep learning models, and outputting an MRI image with a restored image quality for the input accelerated MRI image with the input accelerated MRI image as an input of at least one selected deep learning model.
