Model 539
Multipurpose Quality Assurance, Rubber-based
|
|
The Model 539 Multipurpose, a rubber based tissue mimicking phantom, provides 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 and structures of varying sizes and contrasts.
Cystic-like target structures are positioned in-line vertically, permitting an entire target group to be displayed in one view. |
Matching the acoustic impedance of the background and the cystic structures eliminates artifacts caused by distortion, shadowing or enhancement.
Six gray scale targets ranging in contrast from +15 to -15 dB relative to background are provided to evaluate the system's displayed dynamic range and gray scale processing performance. Lifetime warranty. |
