Document Type and Number:
Japanese Patent JP6903495
Kind Code:
B2
Abstract:
To provide an X-ray CT apparatus which prevents a contrast medium from overtaking and eliminates ineffective exposure caused by re-imaging.SOLUTION: A control part in the X-ray CT apparatus predicts the peak of a contrast effect based on an imaging condition and calculates and displays (steps S201-S202) a threshold prediction line, estimates (step S211) the measured value estimation line of a future CT value from a tomographic image of contrast imaging (steps S207-S208), compares (step S212) the threshold prediction line with the measured value estimation line, and changes (step S213) the imaging condition in accordance with a comparison result.SELECTED DRAWING: Figure 2
