When recalled the system is automatically setup to reflect the programmed baseline values, thereby reducing the

potential for errors.

General Guidelines for Setting Up the Phantom for Scanning

1. Place the phantom on a clean, flat surface with scan surface positioned for use.

2. Apply an adequate amount of low viscosity gel or water to the scan surface. If water is used, fill the

scanning well slowly to avoid introduction of air bubbles.

3. Set-up the imaging system-transducer pair in accordance with the established baseline values. Record

these settings on the quality assurance record.

Re-certification of an ATS rubber-base phantom can be performed at any time in accordance with an individual

institution's quality assurance procedure. ATS produces a test block of TM material for every rubber-based

phantom sold. The test block is used to measure the acoustic properties of the phantom as part of the products

final quality assurance procedure. The test block is retained at the company for future reference and testing

during the re-certification process.

Procedure for phantom re-certification is simple. The phantom is returned to our facility with all shipping charges

paid by the customer. We perform the following steps:

1. Upon arrival, the phantom is inspected for physical damage.

2. The test block is retrieved from the storage library and the acoustic properties are measured.

3. The phantom is than scanned repeating all of the original tests.

4. Results are than compared with the original results on file.

5. A new Quality Assurance certification document similar to the one originally received when the phantom was

purchased will be issued. The phantom is then returned to our customer.

The Model 570 Multipurpose & Endoscopic phantom is an easy, comprehensive means of evaluating imaging

systems with an operating frequency range of 2.25 to 7.5 MHz. The phantom is designed with a combination of

monofilament line targets for distance measurements and tissue mimicking target structures of varying sizes and

contrasts. Due to the acoustic similarity of the background material and the target structures, artifacts caused by

distortion, shadowing and enhancement have been eliminated. Four gray scale targets ranging in contrast from

+6 to -3 dB are provided to evaluate the system's displayed dynamic range and gray scale processing

performance.

The Model 570 offers a new and improved scan surface design to easily accommodate linear, sector, endoscopic

probes and mechanical sector probes such as used for rectal scanning.
