P128. The “FUN”-concept. An innovative training model for intestinal ultrasound education

M. Höpfner, Rotes Kreuz Krankenhaus, Medizinische Klinik, Kassel, Germany


Medical education and training for intestinal ultrasound is a demanding and time-consuming process as it consists of several experience-depending steps. Especially the all-important and time-consuming process of creating an individual pathology database in the examiner's mind is a challenge for all trainees. A new possibility for intestinal ultrasound (US) training has been made available through the method of Volume Navigation. The method with ‘Fusion & Navigation’ (FuN) may well improve and accelerate the training process for intestinal ultrasound.


Volume Navigation is based on a new 3D technology, which enables a precise and controlled orientation during US-examinations. The basis for this technique is a weak, spherical-shaped magnetic field which is generated around the examination area. The US-probe is fitted with two sensors that are continually detected in the magnetic field. All movements of the probe during the examination are being registered. This detection is the foundation for the orientation within the magnetic field. A stored 3D data block of clinical images is uploaded from the database and projected onto any position (e.g. into the abdomen of a healthy subject). After coupling the volume block to the desired anatomical position a realistically re-examination of an old case (previously investigated patient) is possible.


According to a survey 63 percent of 6 workshops 120 trainees voted this training concept as ‘much better’ and 37% as ‘better’ compared to other educational concepts.

17 percent voted this trainig method as ‘much better‘ compared to workshops with real patients, 67% as ‘better’and 17% as similar.


Volume Navigation makes for a fast and precise training method. If used sensible and focused on certain pathological findings, it closes an decisive gap in clinical US training. Besides the negligible time expenditure no deep going technological understanding of the method is required, which increases the congeniality of the method. Furthermore ethical and other imaginable problems do not occur as the pathological finding is no longer connected to the patient. These aspects are surely the decisive factor championing the use of this method as a new training procedure for intestinal imaging.
