METHODS AND SYSTEMS FOR AUTOMATIC CONTROL OF SUBJECTIVE IMAGE QUALITY IN IMAGING OF OBJECTS

摘要

The present invention relates to method and system for automatic control of image quality in imaging of an object using, for example, an ultrasound system. The method comprises transmitting image generating signals into the object using selected system parameter sets of the imaging system. The imaging system has a number of different system parameter sets based on an image ranking measure reflecting a subjective expert opinion of a pre-defined set of images. The captured images are analyzed with respect to at least one image quality feature to determine an image quality metric for each image. The respective image quality metric for each image are analyzed to identify an image associated with a highest image quality metric and the system parameter set used for generating the image associated with the highest image quality metric can be selected as system parameter set for imaging of the object.

1. A method for automatic control of image quality in ultrasound imaging of an object using an ultrasound system, comprising:
transmitting/receiving ultrasound image signals into the object/from the object using selected system parameter sets of the ultrasound system, wherein the ultrasound system has a number of different system parameter sets based on an image ranking measure reflecting at least one subjective expert opinion of a pre-defined set of ultrasound images; processing the sets of signals into ultrasound images, each image being associated with a system parameter set; analyzing the images with respect to at least one image quality feature to determine at least one image quality metric for each image; analyzing the respective image quality metric for each image to identify an image associated with a highest image quality metric; selecting the system parameter set used for generating the image associated with the highest image quality metric as system parameter set for further ultrasound imaging of the object; and repeating one or more of the steps transmitting/receiving, processing, analyzing and selecting until at least one predetermined quality condition is satisfied, or until an operator manually terminates the process.
