Abstract
An ultrasound imaging system applies multi-line artifact mitigation during scanning and determines relative motion between the subject being scanned and a transducer array (12) of the ultrasound imaging system. A further jail-bar artifact mitigation is applied only when the relative motion exceeds an excessive motion limit.

A method for reducing or eliminating motioned-induced jail-bar artifacts in an ultrasound imaging system that includes a transducer array (12), a beamformer (30) producing RF data from pressure pulses received by the transducer array, a detector (34) for processing the RF data output by the beamformer, a scan converter (40) for converting the processed RF data to image data in an image data format, and a display (50) for displaying an image of the scanned subject based on the image data, the method comprising the steps of
- (a) scanning, by the transducer array (12), a subject to be imaged and applying multi-line artifact mitigation to the scanned data;
- (b) determining whether relative motion between the transducer array and the subject to be image exceeds an excessive motion limit;
- (c) if the excessive motion limit is exceeded, initiating a jail-bar artifact mitigation.
An ultrasound imaging system for reducing or eliminating motion-induced jail-bar artifacts, the system comprising:
- a transducer array (12) for gathering image data;
- and
- an image processing mechanism (300, 30, 31, 32, 34, 36, 40) including a beamformer (30) for receiving pressure pulses from the transducer array and generating RF data and a scan converter (40) for converting the RF data to image data in an image data format, wherein the image processing mechanism is arranged and dimensioned for applying a multi-line artifact mitigation to the ultrasound image, determining whether relative motion between the transducer array and the subject to be image exceeds an excessive motion limit, and initiating further jail-bar artifact mitigation if the relative motion exceeds the excessive motion limit.
