Breast Ultrasound QA Phantom US-4

Ultrasound QA phantom for high precision imaging in the high frequency sonography around 10 MHz that is required in breast examination.
For monthly basic quality check of ultrasound images, as well as longer term quality assurance to maintain consistency of the performance of scanners and transducers.
Four kinds of targets, gray scale, cyst targets, dot targets and 45 degrees line target at 2 depth, 10mm(0.4 inch)and 20mm(0.8 inch).
Backgraound of each phantom block is of different attenuation rate and speed of sound.
Detailed spinal resolution as minute 0.5mm(0.02inch)can be assessed.
Mass targets block (contrast resolution)
Gray Scale targets

10 step gray scale targets. Find the optimal gain to visualize all targets clearly and with even change in enchogenicities. Then keep the gain for subsequence assessment session.


Cyst targets

4 targets with different diameter from 1mm(0.04inch) to 4mm(0.16 inch). Visualize the four targets as clear as possible. Then check their roundness and if the 1mm(0.04inch) dia. target can be properly recognized.


Dot targets block (spatial resolution)

Dot targets

Dot targets for horizontal and vertical resolution. Spaving from 0.5mm(0.02inch)to3mm(0.12inch).


45 degrees line target

Infkuence on the image quality by the slice thickness can be assessed. Consists of two dot targets with 2mm(0.08inch) distance with a line target embedded horizontally with 45 degrees from the front wall to the back wall.
