Real-time dose measurement in minibeam radiotherapy using radioluminescence imaging.

Purpose: Minibeam radiotherapy (MBRT) uses small parallel beams of radiation to create a highly modulated dose pattern. The aim of this study is to develop an optical radioluminescence imaging (RLI) approach to perform real-time dose measurement for MBRT.

Methods: MBRT was delivered using an image-guided small animal irradiator equipped with a custom collimator.

Advancements and applications of artificial intelligence in cardiovascular imaging: a comprehensive review.

Artificial intelligence (AI) is transforming cardiovascular imaging by offering advancements across multiple modalities, including echocardiography, cardiac computed tomography (CCT), cardiovascular magnetic resonance (CMR), interventional cardiology, nuclear medicine, and electrophysiology. This review explores the clinical applications of AI within each of these areas, highlighting its ability to improve patient selection, reduce image acquisition time, enhance image optimization, facilitate the integration of data from different imaging modality and clinical sources, improve diagnosis and risk stratification. Moreover, we illustrate both the advantages and the limitations of AI across these modalities, acknowledging that while AI can significantly aid in diagnosis, risk stratification, and workflow efficiency, it cannot replace the expertise of cardiologists.

Polymer-free versus biodegradable-polymer drug-eluting stent in patients undergoing percutaneous coronary intervention: an assessor-blind, non-inferiority, randomised controlled trial.

Background: Few data are available on polymer-free drug-eluting stents in patients undergoing percutaneous coronary intervention (PCI).

Aims: We aimed to determine the efficacy and safety of a polymer-free amphilimus-eluting stent (AES), using a reservoir-based technology for drug delivery, compared with a biodegradable-polymer everolimus-eluting stent (EES).

Methods: This was a randomised, investigator-initiated, assessor-blind, non-inferiority trial conducted at 14 hospitals in Italy (ClinicalTrials.

Origin of the Temperature Dependence of Gate-Induced Drain Leakage-Assisted Erase in Three-Dimensional nand Flash Memories.

Through detailed experimental and modeling activities, this paper investigates the origin of the temperature dependence of the Erase operation in 3D nand flash arrays. First of all, experimental data collected down to the cryogenic regime on both charge-trap and floating-gate arrays are provided to demonstrate that the reduction in temperature makes cells harder to Erase irrespective of the nature of their storage layer. This evidence is then attributed to the weakening, with the decrease in temperature, of the gate-induced drain leakage (GIDL) current exploited to set the electrostatic potential of the body of the nand strings during Erase.

Key steps in exposure techniques for robotic total mesorectal excision (TME).
