Subjective Versus Quantitative Methods of Assessing Breast Density

Diagnostics, 2020
In order to find a consistent, simple and time-efficient method of assessing mammographic breast density (MBD), different methods of assessing density comparing subjective, quantitative, semi-subjective and semi-quantitative methods were investigated ...

Proton-counting radiography for proton therapy: a proof of principle using CMOS APS technology [PDF]

, 2014
Despite the early recognition of the potential of proton imaging to assist proton therapy (Cormack 1963 J. Appl. Phys. 34 2722), the modality is still removed from clinical practice, with various approaches in development. For proton-counting radiography

Ultrasound diagnosis of ulnar nerve entrapment by confirming baseline cross-sectional area measurement for normal and abnormal nerves

South African Journal of Radiology, 2015
Background: Magnetic resonance imaging is most commonly employed, alongside electrodiagnostic studies, in the diagnosis of ulnar nerve entrapment. It is expensive, time consuming, not readily available to the general public, and limits imaging to a ...
