Focused ultrasound surgery (FUS) is a non-invasive method for tissue ablation that has the potential complete and controlled local tumour destruction with minimal side effects. The treatment of abdominal organs such as liver, however, requires particular technological support in order to enable safe, efficient effective treatment. As FUS applied from outside patient's body, suitable imaging methods, magnetic resonance or diagnostic ultrasound, are needed guide track procedure. To facilitate...
This paper introduces a general implementation procedure for the measurement of harmonic phase angles using Power Quality (PQ) instruments. It is intended to fill this gap standards IEC 61000-4-7 and 61000-4-30, particular with focus on grid measurements. While single time instant well defined, focuses methods aggregate in frequency time. The application illustrated different simulated real data. Moreover, accuracy angle procedures test are provided.
Focused ultrasound (FUS) is rapidly gaining clinical acceptance for several target tissues in the human body. Yet, treating liver targets not clinically applied due to a high complexity of procedure (noninvasiveness, motion, complex anatomy, blood cooling effects, shielding by ribs, and limited image-based monitoring). To reduce complexity, numerical FUS simulations can be utilized both treatment planning execution. These use-cases demand highly accurate computationally efficient...
Purpose The accuracy of a numerical simulation cryoablation ice balls was evaluated in gel phantom data as well clinical kidney and lung cases.Materials methods To evaluate the accuracy, 64 experimental single-needle cryoablations 12 multi-needle phantoms were re-simulated with corresponding freeze-thaw-freeze cycles. simulated temperatures compared over time measurements thermocouples. For single needles, temperature values at each thermocouple location. multiple Euclidean distances between...
Focused ultrasound (FUS) is entering clinical routine as a treatment option. Currently, no clinically available FUS system features automated respiratory motion compensation. The required quality standards make developing such challenging. A novel with compensation described, developed the goal of use. comprises MR device and transducer system. controller very generic could use any suitable or device. image sequences (echo planar imaging) are acquired for both observation thermometry. Based...
Design, embodiment, and experimental study of a novel concept extracorporeal phased array ultrasound transducer for prostate cancer regional deep hyperthermia treatments using transperineal acoustic window is presented. An optimized design applicator was derived from modelling software where thermal fields were computed based on anatomical data. Performance tests have been experimentally conducted gel phantoms tissues, under 3T MRI guidance PRFS thermometry. Feedback controlled (ΔT = 5 °C...
Introduction: The novel Trans-Fusimo Treatment System (TTS) is designed to control Magnetic Resonance guided Focused Ultrasound (MRgFUS) therapy ablate liver tumours under respiratory motion. It crucial deliver the acoustic power within tolerance limits for effective tumour treatment via MRgFUS. Before application in a clinical setting, evidence of reproducibility and reliability must safe practice.Materials methods: TTS software delivers ExAblate-2100 Conformal Bone (CBS) transducer. A...
Phase-contrast MRI (PC MRI) can be used to assess blood flow dynamics noninvasively inside the human body. The acquired images reconstructed into vector fields. Traditionally, streamlines computed based on fields visualize patterns and particle trajectories.The traditional methods may give a false impression of precision, as they do not consider measurement uncertainty in PC images. In our prior work, we incorporated computation trajectories.As major part contribution, novel numerical scheme...
Article Internationale Einkünfteabgrenzung: Anmerkungen zum BFH-Urt. v. 9.8.2023 – I R 54/19 aus Sicht von Herrn Dr. Michael Schwenke, BFH was published on April 1, 2024 in the journal SteuerRundschau (volume 13, issue 4).
Non-invasive ablation and hyperthermia treatments of abdominal organs using High Intensity Focused Ultrasound (HIFU) still impose severe challenges. Especially for liver kidney treatments, the target motion accessibility over entire respiratory cycle make application HIFU difficult. To allow a safe, effective, efficient treatment, detailed planning monitoring intervention is needed. Current general-purpose physics simulation software cannot fulfill real-time requirements therapy-monitoring...
The application of FUS in abdominal organs such as the liver or kidneys is impeded by a number complications. One most challenging organ motion due to breathing. To achieve ablation target within moving system has be steered focus on same anatomical position. We present prototypical that tracks an ex vivo ovine via diagnostic ultrasound (US) and adjusts focal spot fixed
Abstract Organ motion is a major problem for Focused Ultrasound Surgery (FUS) of liver tumors. We present phantom mimicking human respiratory (20 mm range, 3 − 7 s/cycle) and the evaluation an ultrasound-tracked steered FUS system on that phantom. Temperature curves are recorded while sonicating in moving static The temperature correlate well show ability to compensate breathing like motion.
