Title:
X-RAY DIAGNOSTIC DEVICE AND MEDICAL IMAGE PROCESSING DEVICE
Document Type and Number:
Japanese Patent JP2023148430
Kind Code:
A
Abstract:
To generate a medical image in which artifacts due to saturation are reduced.SOLUTION: An X-ray diagnostic device includes a first reading part, a second reading part, an acquisition part, an estimation part, and a correction part. The first reading part causes an X-ray detector to execute non-destructive reading of signals accumulated in an X-ray detection element before ending X-ray exposure. The second reading part causes the X-ray detector to execute destructive reading of signals accumulated in the X-ray detection element after X-ray exposure. The acquisition part acquires first projection data generated on the basis of the signals read by the non-destructive reading, and acquires second projection data generated on the basis of the signals read by destructive reading. The estimation part estimate a saturation region in which saturation is occurring on the basis of the second projection data. The correction part replaces signals in the saturation region in the second projection data with signals in the saturation region in the first projection data.SELECTED DRAWING: Figure 1
