Medical examination installation with improved image contrast |
摘要 |
A medical installation for examining a patient irradiates at least a portion of the patient with an examination field, and detects the attenuated field and generates an image therefrom. During exposure of the patient to the examination field, a contrast agent injector is operated to intermittently inject contrast agent into the patient at a selected frequency. The image is generated of the patient at an image pick-up frequency, and the frequency of injection of the contrast agent may be matched to, or differ from, the image pick-up frequency. The liquid injected into the patient will have alternating sections with and without contrast agent following in succession.
