Podium - Personal online dosimetry using computational methods [PDF]

, 2019
Individual monitoring of radiation workers is essential to ensure compliance with official dose limits and to allow application of the ALARA principle. Routine monitoring of staff is usually performed by means of passive dosimeters.

Development of an adjustable dynamic phantom for testing deviceless motion correction algorithm in PET

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Respiratory motion during PET Imaging leads to blurring, volumetric overestimation, and reduced quantitative accuracy. Deviceless motion correction algorithms (MCA) such as OncoFreeze (OF) by Siemens Healthineers (Forchheim, Germany) extract respiratory waveforms from list‐mode data but require validation that cannot be obtained in ...

In‐Depth optimization and characterization of prostatic and penile vessel imaging with Ferumoxytol‐enhanced magnetic resonance imaging

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Vasculogenic erectile dysfunction (ED) arises from impairment of the vascular supply to the penis and requires reliable quantitative imaging for diagnosis, management, and longitudinal monitoring, particularly after pelvic surgery or radiotherapy.

Characterization and calibration of the iQID digital autoradiography system for direct quantitative imaging of beta‐emitters in tissue samples

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Autoradiography provides microscale mapping of radionuclide distributions, offering a promising approach to complement nuclear medicine imaging for small‐scale radiopharmaceutical therapy (RPT) research. However, while quantitative protocols for α‐emitters are well‐established, comparable methods for β‐emitters, such as the widely ...

Photon minibeam‐based LATTICE radiotherapy for small and medium‐sized tumors: A dosimetric planning study

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Lattice radiotherapy (LRT) is a spatially fractionated technique that delivers three‐dimensional high‐dose vertices within tumors. However, conventional LRT is constrained by geometric limitations when applied to small and medium‐sized tumor volumes, primarily due to the large beam sizes that restrict optimal lattice pattern ...

A hybrid deep learning framework for real‐time speckle reduction and image enhancement on portable ultrasound systems

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Speckle patterns in ultrasound images often obscure anatomical details, leading to diagnostic uncertainty. Recently, various deep learning‐based techniques have been introduced to effectively suppress speckle; however, their high computational costs pose challenges for low‐resource devices, such as portable ultrasound systems ...
