Does elevating image receptor increase breast receptor footprint and improve pressure balance? (2015)
Journal Article

There is no consensus in the literature regarding the image receptor (IR) position for the cradio-caudal
projection in mammography. Some literature indicates the IR should be positioned to the infra mammary
fold (IMF); other literature suggests the... Read More about Does elevating image receptor increase breast receptor footprint and improve pressure balance?.

Observer studies in mammography (2015)
Book Chapter

Mammography is a special imaging technique and is unusual in a number of ways: Some of these are technical because of the type of tissue under investigation and some apply to the distinctive nature of the client group. But in one important aspect mam... Read More about Observer studies in mammography.

Breast compression - an exploration of problem solving and decision making in mammography (2014)
Journal Article
Nightingale, J., Murphy, F., Robinson, L., Newton-Hughes, A., & Hogg, P. (2015). Breast compression - an exploration of problem solving and decision making in mammography. Radiography, 21(4), 364-369. https://doi.org/10.1016/j.radi.2014.11.004

Objective: Breast compression decreases radiation dose and reduces potential for motion and geometric unsharpness, yet there is variability in applied compression force within and between some centres. This article explores the problem solving proces... Read More about Breast compression - an exploration of problem solving and decision making in mammography.

Extra patient movement during mammographic imaging : an experimental study (2014)
Journal Article

Objectives: To determine if movement external to the patient occurring during mammography may be a source of image blur. Methods: Four mammography machines with seven flexible and nine fixed paddles were evaluated. In the first stage, movement at the...

A 6 year study of mammographic compression force : practitioner variability within and between screening sites (2014)
Journal Article

Background
The application of compression force in mammography is more heavily influenced by the practitioner rather than the client. This can affect client experience, radiation
dose and image quality. This research investigates practitioner comp... Read More about A 6 year study of mammographic compression force : practitioner variability within and between screening sites.
