The International Transcranial Ultrasonic Stimulation Safety and Standards Consortium (ITRUSST) has developed a set of standardized reporting guidelines for transcranial ultrasound stimulation (TUS) to enhance comparability and reproducibility across studies. The guidelines focus on the ultrasound aspects of TUS experiments, including the transducer and drive system, free field acoustic parameters, pulse timing parameters, and in situ estimates of exposure parameters in the brain. The document provides detailed explanations and checklists for reporting these parameters, ensuring that studies are conducted and reported consistently. Key components include descriptions of transducer and drive systems, free field acoustic pressure amplitude and spatial characteristics, pulse timing parameters, and methods for estimating in situ exposure parameters such as pressure amplitude, mechanical index, thermal metrics, and intensity parameters. The guidelines aim to standardize the reporting of TUS parameters, facilitating better understanding and reproducibility in TUS research and applications.The International Transcranial Ultrasonic Stimulation Safety and Standards Consortium (ITRUSST) has developed a set of standardized reporting guidelines for transcranial ultrasound stimulation (TUS) to enhance comparability and reproducibility across studies.
