Ultrasonic diagnostic imaging system with automatically controlled contrast and brightness |
摘要 |
An ultrasonic diagnostic imaging system includes a predetermined TGC characteristic which is automatically selected or calculated at the initiation of a diagnostic procedure. An automatic TGC circuit analyzes current image data to calculate an adjustment to the predetermined TGC characteristic when activated by the clinician. The ultrasound system produces a displayed TGC curve which illustrates the predetermined TGC characteristic as modified by automatic adjustment and any manual refinement done by the clinician. In a preferred embodiment automatic TGC modification is accompanied by automatic overall gain and dynamic range adjustment to automatically optimize image quality.
