SPHERICAL LESION PHANTOM MODEL 408LE

The Spherical Lesion Phantom Model 408 LE provides a unique way of testing resolution performance of ultrasound scanners. The Spherical Lesion Phantom contains 2 mm and 4 mm diameter tissue mimicking spherical lesions which lie in a single plane at the center of the phantom. Axial, lateral and elevational resolution are accounted for simultaneously and equally for all types of ultrasound systems and configurations. In the 2 mm section, there are 105 anechoic spheres at 0.5 cm depth intervals and in the 4 mm section there are 211 anechoic spheres at 0.75 cm depth intervals.

Spherical Lesion

Phantom

Model 408 LE

 

Ultrasound imagine quality in three dimensions: axial, lateral and elevational.  The Spherical Lesion Phantom Gammex 408

LE provides a unique way of testing resolution performance of ultrasound scanners.  The Spherical Lesion Phantom

contains 2 mm and 4 mm diameter tissue mimicking spherical lesions which lie in a single plane at the center of the

phantom. Axial, lateral and elevational resolution are accounted for simultaneously and equally for all types of ultrasound

systems and configurations. In the 2 mm section, there are 105 anechoic spheres at 0.5 cm depth intervals and in the 4 mm

section there are 211 anechoic spheres at 0.75 cm depth intervals.

 

The Spherical Lesion Phantom Gammex 408 LE incorporates our Tissue Mimicking (TM) gel which provides a smoother

background texture than conventional tissue mimmicking gels. The Gammex gel allows production of lesions with negligible

echogenicity while producing no distal enhancement or shadowing inherent with other gel forms. The TM gel is also

optimized for use with tissue harmonics imaging technology.

 

In addition, the Gammex 408 LE has a new composite film scanning surface that has improved transmission properties so

more of the ultrasonic beam can be transmitted and received.

 

Optional accessories for the Gammex line of Ultrasound phantoms include Soft Foam-Lined Carrying Case, Rigid Case, or

the Precision Ultrasound Transducer Guide.

 

This ultrasound image demonstrates the anechoic spheres contained in the Spherical Lesion Phantom

Gammex 408 LE. Note the well defined 2 mm and 4 mm targets.
