Abstract—Regional Anaesthesia (RA) is a rapidly growing field,
which appears to be a great challenge for novices in terms of
learning a new technique. Although many training methods are
available, they do not provide a sufficient training that gives
novices an opportunity to gain all skills required to perform RA
safely. New prototypes of RA simulator have been developed
under project RASimAs (Regional Anaesthesia Simulator and
Assistant). The RASimAs prototypes are based on a Virtual
Physiological Human model that includes anatomy, physics and
biological functions. One of the possible ways to develop this model
is based on the use of existing 3D anatomical models (e.g.,
ZygoteBody, Anatomium3D Anatomy Model). The model for RA
simulator is inducted based on some physiological layers that are
indicated in these 3D models separately. This indicates existence of
intersections between different layers, what is not good for
development of RA simulator. Therefore, intersections between
different layers of Zygote Male Human Anatomy Collection v.4.0
(a part of ZygoteBody) are considered and investigated in this
paper.

I. INTRODUCTION
The principal goal of use of information technologies in
medicine is improvement of health care. This application
provides a new concept of Health Information Technology (HIT)
that supposes use of computer hardware and software that deals
with the storage, retrieval, sharing, and use of health care data,
information, and knowledge for communication and decision-
making [1]. The HIT is composed of computers and
communications attributes that are combined together to build
systems for health monitoring and diagnosis, medical treatment,
and patient care. Application of such system allows decreasing
medical error and increasing level of patient care. An important
part or component of this system is medical personnel. Because
of that, the development of a high-reliable healthcare system has
to be implemented in conjunction with creation of background
for rise of qualification level of medical staff. Inadequate
technical skills resulted from limited training methods are one of
the most difficult challenges faced by trainees today. Current
teaching methods have failed to provide the sufficient training
for young medical specialists. They include simple phantoms,
cadavers, video teaching and, if it is possible, training on human
volunteers or colleagues. These methods have limited
capabilities and, therefore, development of new training
methods is a current issue. A possible way to solve these
limitations is application of computer-based simulator.
The important part of any medical simulator is a virtual 3D
anatomical model [2–4]. Virtual Environment (VE) is used for
different purposes in medicine and healthcare [5], and it intends
to provide a balance between engagement and aspects of
learning using the simulator. VE can allow a wider range of
content and the enhanced learning through the different subjects
and learning methodologies [3, 4]. Typically, medical simulators
are developed based on a Virtual Physiological Human (VPH)
3D model. This implies that reliability of a simulator depends on
the quality of the used VPH model. As a rule, model’s quality
and simulator’s reliability are evaluated in step of testing after
designing the simulator. Reliability analysis of a system in
design is a complex and unformalized problem. This problem is
caused by a lot of specifics of the elaborated system (in
particular, the medical simulator). In this paper, we consider the
preliminary reliability evaluation of the simulator for Regional
Anaesthesia (RA) in the step of design. This simulator has been
developed under the project RASimAs (Regional Anaesthesia
Simulator and Assistant) [5, 6]. The evaluation is implemented
by qualitative analysis of the designed VPH model. This
analysis allows us to obtain basic statistics about possible
inconsistencies. These inconsistencies are interpreted as initial
faults of the model, which can cause failure and unacceptable
functioning of the simulator.
