Abstract Purpose Patient-specific dosimetry is required to ensure the safety of molecular radiotherapy and predict response. Dosimetry involves several steps, first which determination activity radiopharmaceutical taken up by an organ/lesion over time. As uncertainties propagate along each subsequent steps (integration time–activity curve, absorbed dose calculation), establishing a reliable quantification essential. The MRTDosimetry project was European initiative bring together expertise in...
We present new $\ensuremath{\Sigma}$ beam asymmetry data for $\ensuremath{\eta}$ meson photoproduction on the proton, using a novel tagged, laser backscattered, linearly polarized photon up to 1.1 GeV. The show large, positive asymmetries, at all incident energies. In addition ${S}_{11}(1535)$ and ${D}_{13}(1520)$ resonances necessary reproduce cross sections, ${P}_{13}(1720)$ ${D}_{15}(1675)$ ``four stars'' contribute observable, but cannot strong forward asymmetries measured energies...
PET/CT has recently been shown to be a viable alternative traditional post-infusion imaging methods providing good quality images of 90Y-laden microspheres after selective internal radiation therapy (SIRT). In the present paper, first we assessed quantitative accuracy 90Y-PET using an anthropomorphic phantom provided with lungs, liver, spine, and cylindrical homemade lesion located into hepatic compartment. Then, explored different computational approaches on dose calculation, including (I)...
The double π0 photoproduction off the proton has been measured in beam energy range of 0.65–1.5 GeV. total and differential cross sections Σ asymmetry were extracted. section for first time third resonance region nucleon shows a prominent peak. interpretation these results by two independent theoretical models infers mostly selective excitation P11- D13-nucleon resonances.Received 17 January 2003DOI:https://doi.org/10.1103/PhysRevLett.90.222001©2003 American Physical Society
Interlaboratory exercises are a good tool to compare the response of different systems same quantity and identify possible inconsistencies between them. One main goals EMPIR 19ENV01 traceRadon project is harmonize radon flux measurements based on methodologies. In framework Project, two intercomparison campaigns were carried out in October 2021 at high low source areas. Four institutions participated field with their own systems. Every system was specific monitor (diffusion or pump mode) an...
The differential cross section for the reaction p(γ,ηp) has been measured from threshold to 1100 MeV photon laboratory energy. For first time, region of S11(1535) resonance is fully covered in a photoproduction experiment and will allow precise extraction its parameters at point. These high precision data together with already beam asymmetry provide stringent constraints on new couplings baryon resonances η meson.
the gamma-emitting radionuclide Technetium-99m (99mTc) is still workhorse of Single Photon Emission Computed Tomography (SPECT) as it used worldwide for diagnosis a variety phatological conditions. 99mTc obtained from 99Mo/99mTc generators pertechnetate ion, which ubiquitous starting material preparation radiopharmaceuticals. 99Mo in such currently produced nuclear fission reactors by-product 235U fission. Here we investigated an alternative route production by irradiating natural metallic...
The $ \Sigma$ beam asymmetry in \eta^{\prime}$ photoproduction off the proton was measured at GrAAL polarised photon with incoming energies of 1.461 and 1.480 GeV. For both as a function meson production angle shows clear structure, more pronounced lowest one, change sign around 90^{\circ}$ . observed behaviour is compatible P-wave D-wave (or S-wave F-wave) interference, closer to threshold stronger. results are compared existing state-of-the-art calculations that fail account for data.
