AAPM‐HPS medical physics practice guideline 16.a: medical health physics scope of practice [PDF]
J Appl Clin Med PhysAbstract The field of Medical Health Physics (MHP) lies at the intersection of Health Physics (HP) and Medical Physics (MP). The MHP is one of the five subfields identified by the AAPM that in which a Qualified Medical Physicist (QMP) may operate independently to provide clinical professional services.

Femoral Skeletal Growth in Early Infancy Assessed by Radiofrequency Echographic Multi-Spectrometry. [PDF]
J Clin UltrasoundRadiofrequency echographic multi‐spectrometry (REMS) acquisition of raw ultrasound radiofrequency signals from neonatal bone. Signals undergo preprocessing and frequency‐domain analysis to extract spectral features reflecting bone properties. A software‐guided procedure then identifies and selects standardized regions of interest (ROIs).
