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 precise 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 evaluation methods and devices to augment and enhance their capabilities and range of application.
