Anthropomorphic phantoms offer a promising solution to minimize animal testing, enable medical training, and support the efficient development of devices. The adjustable mechanical, biochemical, imaging properties polyvinyl alcohol cryogel (PVA-C) make it an appropriate phantom material for mimicking soft tissues. Conventional manufacturing (CM) aqueous solutions requires constant stirring, using heated water bath, monitoring. To explore potential improvements in dissolution PVA crystals...
<title>Abstract</title> Microwave ablation (MWA) of hepatic tumors benefits from MR thermometry, enabling real-time temperature monitoring to guide treatment and protect healthy tissue. However, thermometry in the abdomen is challenging due respiratory intestinal motion. This study evaluates two advanced 3D imaging sequences, Stack-of-Stars (Stars) Stack-of-Spirals (Spirals), for precise MWA phantom volunteer experiments. Spirals demonstrated superior precision, with a standard deviation...
Abstract Purpose In vivo studies are often required to prove the functionality and safety of medical devices. Clinical trials costly complex, adding ethical scrutiny animal testing. Anthropomorphic phantoms with versatile functionalities can overcome these issues regard education or an effective development assistance systems during image-guided interventions (e.g., robotics, navigation/registration algorithms). this work, MRI-compatible customizable motion phantom is presented mimic...
Abstract Purpose Surgical robotics have demonstrated their significance in assisting physicians during minimally invasive surgery. Especially, the integration of haptic and tactile feedback technologies can enhance surgeon’s performance overall patient outcomes. However, current state-of-the-art lacks such interaction opportunities, especially robotic-assisted interventional magnetic resonance imaging (iMRI), which is gaining importance clinical practice, specifically for percutaneous needle...
Abstract The increased clinical relevance of image-guided procedures, particularly interventional magnetic resonance imaging (iMRI), highlights the need for advanced devices and robotics to optimize those procedures. To enable a realistic integration into workflow, robotic-patient interfaces (RPI) are required ensure both functionality usability. However, current concepts have issues with patient accessibility safety, user handling, or performing interventions on versatile body regions. This...
Motivation: 3D MR-thermometry enhances microwave ablation success by providing real-time temperature and insights. However, clinical availability is limited due to challenges such as breathing motion electromagnetic interferences. Goal(s): Our study conducts comparing stack-of-stars a stack-of-spirals sequences using clinically approved generator phantoms simulating motion. Approach: Temperature precision of zones both were compared. Results: Stack-of-spirals sequence seems be the superior...
