Ma, W., Hogg, P., & Howard, D. (2017). Closed-loop control of compression paddle motion to reduce blurring in mammograms. Medical Physics, 44(8), 4139-4147. https://doi.org/10.1002/mp.12333

Background: Since the introduction of full field digital mammography (FFDM) a large number of UK breast cancer screening centers have reported blurred images, which can be caused by movement at the compression paddle during image acquisition. Purpos... Read More about Closed-loop control of compression paddle motion to reduce blurring in mammograms.

A JAFROC study of nodule detection performance in CT images of a thorax acquired during PET/CT (2017)
Journal Article
Thompson, J., Wareing, A., Szczepura, K., Vinjamuri, S., & Hogg, P. (2017). A JAFROC study of nodule detection performance in CT images of a thorax acquired during PET/CT. Radiography, 23(3), 191-196. https://doi.org/10.1016/j.radi.2017.03.001

Purpose Two types of CT images (modalities) are acquired in PET/CT: for attenuation correction (AC) and diagnosis. The purpose of the study was to compare nodule detection and localization performance between these two modalities. Methods CT...

Blurred digital mammography images : an analysis of technical recall and observer detection performance (2017)
Journal Article
Ma, W., Kelly, J., Millington, S., Hilton, B., Borgan, R., Aspin, R., …Hogg, P. (2017). Blurred digital mammography images : an analysis of technical recall and observer detection performance. British Journal of Radiology, 90(1071), 20160271. https://doi.org/10.1259/bjr.20160271

Background: Blurred images in Full Field Digital Mammography (FFDM) are a problem in the UK Breast Screening Programme. Technical recalls may be due to blurring not being seen on lower resolution monitors used for review. Objectives: This study ass...

Analysis of effective and organ dose estimation in CT when using mA modulation : a single scanner pilot study (2017)
Journal Article
Tootell, A., Szczepura, K., & Hogg, P. (2017). Analysis of effective and organ dose estimation in CT when using mA modulation : a single scanner pilot study. Radiography, 23(2), 159-166. https://doi.org/10.1016/j.radi.2017.02.006

Effective dose (ED) estimation in CT examinations can be obtained by combining dose length product (DLP) with published ED per DLP coefficients or performed using software. These methods do not account for tube current (mA) modulation which is influe...

Compression forces used in the Norwegian Breast Cancer Screening Program (2017)
Journal Article
Waade, G., Moshina, N., Sæbuødegård, S., Hogg, P., & Hofvind, S. (2017). Compression forces used in the Norwegian Breast Cancer Screening Program. British Journal of Radiology, 90(1071), https://doi.org/10.1259/bjr.20160770

Objectives: Compression is used in mammography to reduce breast thickness, which is claimed to improve image quality and reduce radiation dose. In the Norwegian Breast Cancer Screening Program (NBCSP), the recommended range of compression force for f...

Health behavioural theories and their application to women’s participation in mammography screening : a narrative review (2017)
Journal Article
narrative review. Journal of Medical Imaging and Radiation Sciences, 48(2), 122-127. https://doi.org/10.1016/j.jmir.2016.12.002

The most effective method of detecting breast cancer amongst asymptomatic women is by mammography screening. Although, most countries have this preventive measure in place for women within their society; most of these programmes still struggle with w...
