Model 551 provides a comprehensive means of evaluating the performance of higher frequency (approximately 7.5- 20 MHz) ultrasound systems designed to detect small anatomic features.
Our Small Parts Phantom is designed with a combination of monofilament line targets and tissue mimicking cylindrical targets of varying sizes and contrasts. The monofilament line targets have a diameter of 0.05 mm, to optimize the displayed image at frequencies of 7.5 MHz or greater. Four groups of line targets are provided to evaluate the vertical and horizontal calibration measurements, dead zone and axial-lateral resolution. The model 551 provides enhanced axial-lateral resolution targets (down to 0.25mm spacing) over the standard axial-lateral targets over the 551.
The Model 551 is constructed of our rubber-base tissue mimicking material to provide a phantom which is accurate, durable and maintenance free. All ATS urethane phantoms are guaranteed for the useful life of the phantom, defined as 10 years.
