First measurement of the rate K0L → πμνγ

1998

Abstract In a preliminary version of the NA48 experiment at the CERN SPS, in which an iron-scintillator sandwich calorimeter was used as a photon detector, the ratio of K L → πμνγ and K L → πμν decays was measured. The branching ratio BR(K L →πμνγ, E γ ∗ ≥30 MeV )/(K L → πμν ) is found to be (2.08±0.17 +0.16 −0.21 )×10 −3 , where the first error is statistical and the second systematic. The result is in agreement with theoretical predictions.

A multicenter evaluation of a deep learning software (LungQuant) for lung parenchyma characterization in COVID-19 pneumonia

2023

Abstract Background The role of computed tomography (CT) in the diagnosis and characterization of coronavirus disease 2019 (COVID-19) pneumonia has been widely recognized. We evaluated the performance of a software for quantitative analysis of chest CT, the LungQuant system, by comparing its results with independent visual evaluations by a group of 14 clinical experts. The aim of this work is to evaluate the ability of the automated tool to extract quantitative information from lung CT, relevant for the design of a diagnosis support model. Methods LungQuant segments both the lungs and lesions associated with COVID-19 pneumonia (ground-glass opacities and consolidations) and computes derived…

Tubular carcinoma of the breast: Outcome and loco-regional recurrence in 307 patients

2005

Abstract Purpose The aim of this study is to describe the University of Florence experience in evaluating clinical, pathologic and treatment factors as they are related to the outcome and loco-regional recurrence in patients with tubular breast carcinoma. Material and methods Three hundred and seven patients (median age 56.4 years, range 26–91 years) with histological verified tubular carcinoma of the breast were consecutively treated at University of Florence from 1976 to 2001. All patients were followed for a median of 8.4 years (range 3 months to 20 years). Thirty-seven women underwent mastectomy and 270 underwent breast conserving surgery. Positive axillary nodes were found in 15% of pa…

Monte Carlo evaluation of the Filtered Back Projection method for image reconstruction in proton computed tomography

2011

Abstract In this paper the use of the Filtered Back Projection (FBP) Algorithm, in order to reconstruct tomographic images using the high energy (200–250 MeV) proton beams, is investigated. The algorithm has been studied in detail with a Monte Carlo approach and image quality has been analysed and compared with the total absorbed dose. A proton Computed Tomography (pCT) apparatus, developed by our group, has been fully simulated to exploit the power of the Geant4 Monte Carlo toolkit. From the simulation of the apparatus, a set of tomographic images of a test phantom has been reconstructed using the FBP at different absorbed dose values. The images have been evaluated in terms of homogeneity…
