A projection‐domain deep learning approach for respiratory motion correction of myocardial perfusion imaging using a multi‐pinhole solid‐state SPECT

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Myocardial perfusion imagining (MPI) is a nuclear medicine technique used in the assessment of coronary artery disease. Differences in the perfusion of the myocardium at rest and stress and regions of perfusion defects can be indicators of various cardiac disease states. Respiratory motion (RM) can result in the degradation of image

Comparison of three methods of calculation, experimental and monte carlo simulation in investigation of organ doses (thyroid, sternum, cervical vertebra) in radioiodine therapy

Journal of Medical Signals and Sensors, 2012
Radioiodine therapy is an effective method for treating thyroid cancer carcinoma, but it has some affects on normal tissues, hence dosimetry of vital organs is important to weigh the risks and benefits of this method.

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 ...
