“…Starting from 1979, early investigations assessing the feasibility of applying ultrasound imaging for temperature detection in biological tissues were carried out by several research groups [ 159 , 160 , 161 , 162 , 163 , 164 ]. Ultrasound-based thermometry has found certain applications in the field of HIFU [ 35 , 36 , 37 , 38 ], and RFA [ 69 , 70 ] therapies, mainly on hepatic tissues, and to a lesser extent during LA [ 165 , 166 ] and MWA [ 167 ]. Despite the large use of ultrasound imaging in clinical practice, only a few studies have been conducted in the field of myocardial RFA.…”

“…The most commonly used techniques for temperature monitoring during HIFU are non-invasive. Among others, thermometry based on ultrasound [ 35 , 36 , 37 , 38 ] and MRI [ 39 , 40 , 41 ] has been the most exploited. The use of thermal probes embedding fluoroptic fibers [ 42 , 43 ] and thermocouples [ 44 , 45 , 46 ] was also explored but at the expense of the non-invasiveness, which is one of the main advantage of HIFU.…”

Cardiac radiofrequency ablation (RFA) has received substantial attention for the treatment of multiple arrhythmias. In this scenario, there is an ever-growing demand for monitoring the temperature trend inside the tissue as it may allow an accurate control of the treatment effects, with a consequent improvement of the clinical outcomes. There are many methods for monitoring temperature in tissues undergoing RFA, which can be divided into invasive and non-invasive. This paper aims to provide an overview of the currently available techniques for temperature detection in this clinical scenario. Firstly, we describe the heat generation during RFA, then we report the principle of work of the most popular thermometric techniques and their features. Finally, we introduce their main applications in the field of cardiac RFA to explore the applicability in clinical settings of each method.

The present work is aimed at development of a method for estimation of the accuracy of ultrasound thermometry (UST) when applying during local HIFU heating of a tissue-mimicking material (TMM). The method is based on comparison of the ultrasound measurement results with a temperature field reconstructed inside the TMM using data of the infrared (IR) camera surface measurements. In the case presented, the HIFU transducer heated up the TMM by 30 °C for 10 s in the focus area. Ultrasound signals were processed using an in-house UST application software. A 3D temperature field inside the TMM was reconstructed using a method based on the neural network approach. As a result, it has been achieved a good agreement between the UST measurement data and the reconstructed temperature field, especially for the points along the HIFU transducer axis.

High Intensity Focused Ultrasound (HIFU) is widely used in modern medicine. One of the important applications is the ablation of internal organ tumors under the HIFU heating. During this procedure, it is necessary to monitor the temperature in healthy adjacent tissues. Ultrasound thermometry (UST) is a promising non-invasive method of temperature control. The paper presents implementation of the UST technique in case of short-term local heating. A new algorithm suggested for ultrasound data processing improves the accuracy of the ultrasound thermometry technique to 2 °C.
