“…Regarding clinical application of our findings, ultrasound simulation can serve as innovative method in education and training [3][4][5] and preparing staff before handling specialized procedures in UGRA. Here, we show that ultrasound of vessels and peripheral nerves can be reconstructed from 3D-UV with preservation at highresolution ultrasonographic appearance of nervous echo texture [6] by means of a simple electromagnetically tracking system [5]. Such 3D-UV are well suited to study sonoanatomy, learn handling and movement of ultrasound probe, plane interpretation for UGRA and of sonoanatomic landmark structures for specific block techniques.…”

“…Ultrasound simulator and recording system A free-hand recording system as part of an ultrasound simulation system (Ultrasound simulator Reslice, registered trademark by Schallware GmbH, Berlin, Germany, http://www.schallware.de) [5] was coupled to a high-end ultrasound device (Vivid-i, registered trademark by GE Healthcare Ultrasound, Solingen, Germany) with a 12 MHz linear probe (12L). The free-hand recording system consists of a PC with Ubuntu software platform (Linux-based public license, non-commercial software, version 7.10, http://www.ubuntu.com), an electromagnetic tracking system, a mannequin and a probe dummy with localization transmitter, and also consists of a PC with recording software (Schallware Acquisition 2007, Fa.…”

“…Thereby training was more independent of models and patients and also could address real-life scenarios within training courses. Furthermore, ultrasound simulation is of strong interest, because it can provide a large case numbers and thus provide teaching on anatomical variations and pathology [3][4][5].…”

Objective Regarding education in ultrasound-guided regional anaesthesia, we aimed to develop three-dimensional ultrasound volumes (3D-UV) of peripheral nerves for ultrasound simulation. This study mainly addressed to estimate diagnostic feasibility as well as comparison of original ultrasound images with 3D-UV. Methods A free-hand recording system as part of an ultrasound simulation system (Ultrasound simulator Reslice, Schallware GmbH, Berlin, Germany) was coupled to a high-end ultrasound device (Vivid-i, GE healthcare Ultrasound). 3D-UV were recorded as transverse parallel planes from four healthy models and positioned with an electromagnetic tracking system into a mannequin on identical anatomical sites. Using developer software, single B-Mode 3D-UV were combined into 3D-multivolumes (MV). Original short and long axis B-Mode planes were compared with reconstructed planes (reslices).Results A total of 108 3D-UV including vessels of carotid region (n = 22), and peripheral nerves of interscalene (31), axillary (28), femoral groin (8) and distal sciatic (19) were recorded. Visual presentation of reconstructed volumes of vessels and peripheral nerves revealed almost comparable quality to the original B-Mode scans of the model examination. Ultrasonographic nerve structure appearance derived from high-resolution ultrasound recordings could be preserved in reslices of 3D-UV and also in part in the long axis. Conclusions Our data provide a new proof of concept for ultrasound simulation of peripheral nerves in 3D-ultrasound multivolumes based on high-resolution ultrasound technology. It has the ability to provide pathologic findings and may serve as a powerful method for training in regional anaesthesia and critical care ultrasound.

Abstract. Medical ultrasound interpretation requires a great deal of experience. Real-time simulation of medical ultrasound provides a costeffective tool for training and easy access to a variety of cases and exercises. However, fully synthetic and realistic simulation of ultrasound is complex and extremely time-consuming. In this paper, we present a novel method for simulation of ultrasound images from 3D CT scans by breaking down the computations into a preprocessing and a run-time phase. The preprocessing phase produces detailed fixed-view 3D scattering images and the run-time phase generates view-dependent ultrasonic artifacts for a given aperture geometry and position within a volume of interest. We develop a simple acoustic model of the ultrasound for the run-time phase, which produces realistic ultrasound images in real-time when combined with the previously computed scattering image.
