A NEW IMAGING SCIENCE TEST OBJECT FOR PERFORMANCE-MEASUREMENTS OF ULTRASONIC-IMAGING SYSTEMS

We propose a novel test object for ultrasound imaging. The test object , or phantom, is manufactured using thin film techniques allowing prec ise placement of 'digital scatterers' which can produce sophisticated test targets, similar to those that are widely used in imaging science to evaluate displays, printers and electronic imaging systems. These test objects can be used in conjunction with standard performance eval uation methods and devices to augment and enhance their capabilities a nd range of application.
