Medical Physics, EarlyView.Abstract Background Intensity‐modulated proton therapy (IMPT) holds promise for improving outcomes in head‐and‐neck cancer (HNC) patients by enhancing organ‐at‐risk (OAR) sparing. A key challenge in IMPT is ensuring an accurate dose delivery at the distal edge of the tumor, where the steep dose gradients make treatment precision highly sensitive to ...

Medical Application Studies at ELI-NP [PDF]
arXiv, 2012 We study the production of radioisotopes for nuclear medicine in (gamma,gamma') photoexcitation reactions or (gamma,xn + yp) photonuclear reactions for the examples of ^195mPt, ^117mSn and ^44Ti with high flux [(10^13 - 10^15) gamma/s], small beam diameter and small energy band width (Delta E/E ~ 10^-3 -10^-4) gamma beams.

The Prostate, EarlyView.ABSTRACT Background Brain metastases (BMETS) from prostate cancer are rare. Hence, brain imaging in neurologically asymptomatic patients with advanced prostate cancer (aPC) is not routinely performed. Prostate‐specific membrane antigen (PSMA) PET/CT uses a radiotracer that binds to prostate cancer epithelial cells and is FDA‐approved for initial ...

Novel Direct Alpha Spectroscopy Technique for $^{225}$Ac Radiopharmaceutical detection in Cancer Cells [PDF]
arXivTargeted alpha-particle therapy (TAT) employs alpha-emitting radionuclides conjugated to tumor-targeting molecules to deliver localized radiation to cancer cells, showing great promise in treating metastatic cancers. Among these radionuclides, Actinium-225 ($^{225}$Ac, t$_{1/2}$ = 9.9 days) has emerged as a clinically promising candidate.

Optimization of the image contrast in SPECT-CT bremsstrahlung imaging for Selective Internal Radiation Therapy of liver malignancies with Y-90 microspheres [PDF]
arXiv, 2015 The quality of SPECT Bremsstrahlung images of patients treated with Y-90 is poor, mainly because of scattered radiation and collimator septa penetration. To minimize the latter effect, High Energy (HE) or Medium Energy (ME) collimators can be used. Scatter correction is not possible through the methods commonly used for the diagnostic radionuclides (Tc-

VIEW, EarlyView.The tumor immune microenvironment (TIME) plays a critical role in cancer progression and treatment response. Advanced tools like nanotechnology‐empowered sensors to precisely detect at microscopic scales are introduced. These innovations improve the ability to predict patient responses to immunotherapies and identify new therapeutic targets, paving the

A quantitative assessment of Geant4 for predicting the yield and distribution of positron-emitting fragments in ion beam therapy [PDF]
arXivPurpose: To compare the accuracy with which different hadronic inelastic physics models across ten Geant4 Monte Carlo simulation toolkit versions can predict positron-emitting fragments produced along the beam path during carbon and oxygen ion therapy.
