Introduction
The 404GS LE phantom is designed to measure the image quality of small parts and
intra-cavity ultrasound scanning systems. With added grey scale targets, this small parts
phantom can also be used to measure contrast, temporal resolution and system linear-
ity. This Small Parts Phantom permits precise measurements of resolution for testing
for:
•
Axial and lateral resolution targets at 1, 3.5 and 6 cm for precise resolution mea-
surements
•
Low scatter cyst imaging at 1, 2 and 4 mm
•
Attenuation coefficients of either 0.5 or 0.7 dB/cm/MHz
•
7 mm cyst to evaluate system noise and distortion and 7 mm grey scale targets of
-6 dB, +6 dB and high scatter relative to the background.
Limitations of Use
The 404GS LE is designed to be used to aid in the Quality Control testing and monitor-
ing of ultrasound instruments only. The 404GS LE is not to be used to make diagnostic
decisions.
