mamography

For digital mammography what is the National Reference Level dose for the Mean Glandular Dose (MGD) measured on the 2cm PMMA phantom?

1mGy

In Mammography the minimum Aluminium Equivalent Tube Filtration is:

0.5mm

In Mammography the Heel Effect can be used to:

Give a higher intensity at the chest wall

In Mammography the Line Focus Effect can be used to:

Give higher spatial resolution in the breast

A tube with a 23 degree anode angle and a further 6 degree tilt has an effective focal spot size of 0.1 mm. What is the target size on the anode

0.21mm

Why is a Molybdenum (Mo) filter used with a Molybdenum (Mo) target in Mammography?

To produce less polychromatic x-ray spectrum which gives optimum diagnoses in the breast with less dose 

What is the ACR Mammography phantom and what are the minimum detection requirements?

ACR phantoms are standardized quality control tools comprises of 6 fibres, 5 spec groups, 5 masses

Equipment needs to detect 4 fibres, 3 specs and 3 masses to pass
