Simulating Medical Imaging: MRI Simulators, X-Ray Simulators, and CT Simulators

While we have previously covered Ultrasound Simulators like those from CAE Healthcare, VirtaMed, Intelligent Ultrasound, SonoSim, and Simulab, today we focus on other Medical Imaging Simulators like MRI Simulators, X-Ray Simulators, and CT Simulators. These unique patient simulators enable healthcare simulation programs to simulate medical imaging procedures with standardized and repeatable learning objectives that provide both accuracy and quality. Some of them are even already available in VR! Allied health programs educating and training for the use of medical imaging devices will appreciate the insights gathered here.

medspace.VR

Covering most of the imaging medical devices out there, medspace.VR’s product portfolio includes x-ray simulation, C-Arm simulation, and CT simulation with high quality 3d rendered graphics which look like very realistic. Kelly Wilson-Stewart, Medical Imaging Clinical Educator and Radiographer shared that “With increasing pressures on clinical simulation programs because of the limited availability of facilities and clinical placements, medspace.VR has enormous potential to bring pre-clinical skills training into a safe and remotely accessible virtual environment – a great tool for Medical Imaging educators!”

Corsmed

Often referred to as “the flight simulator of MRI”, Corsmed’s MRI simulator lets both new and experienced users practice and improve their skills in a safe setting. Practitioners can select a preferred scanner system and patient type, and while using the same as a real scanner,  set the slice positions, pulse sequence and parameters. After running the simulated scan, the MRI simulator returns the same resulting images as on a real scanner, including noise and artifacts. As far as we can tell, this is the only high quality MRI Simulation software in the world!

MRI simulations on this level of sophistication usually require expensive hardware and extensive knowledge in MR-physics, MR-simulations and software development. By providing the medical simulation hardware on cloud, educators are almost immediately able to provide programs with high quality with user-friendly training, on demand.

Recent studies (Ma et al., 2013 and Xanthis et al., 2015) have shown that the incorporation of Magnetic Resonance Imaging (MRI) simulations can significantly improve quantitative MRI through the utilization of advanced MRI simulations of the pulse sequence on a large population of spins and the generation of a database of simulated MR signals. Despite the increasing interest in incorporating simulation-aided analyses in quantitative MRI, several MR research groups do not have access to a MR simulation platform or the computational resources required to develop an advanced MR simulation platform.

coreMRI from Corsmed provides high performance and scalability allowing MRI educators to configure advanced MRI experiments without the constraints imposed by experimentation in a true MRI scanner (such as time constraint and limited availability of MR scanners). Of crucial importance, Corsmed’s systems allow for MRI simulation without upfront investment for purchasing advanced MRI computer systems and without any user expertise on computer programming or MR physics.

Virtual Medical Coaching

Providing a CT Simulator and an X-Ray Simulator, the team from Virtual Medical Coaching provides training centers with the ability to use multiple types of imaging machinery with different conditions and pathologies of the patient in both desktop and VR environments. They also train for radiation safety and dosimetry in the OR.

Their virtual reality radiography simulations guide learners through the full end to end process of assessing anatomy, x-ray positioning, and pathology for a dynamic range virtual patients. During sessions, learners are guided through areas of weakness with full feedback reports on progress made. The Virtual Medical Coaching operating theatre simulation allows an anesthesiologists, interventional radiologists, nurses, and radiographers to experience tasks which they would be required to do in real clinical environments when considering radiation safety.

Their CTSimulate training, practice and assessment mode offers a variety of CT theory and practical scanning using Virtual Medical Coaching’s online computer simulations. This module allows educators to train for basic to advanced CT imaging of the head, dose reduction techniques, post-processing, reconstruction parameters and more.

The Virtual Medical Coaching medical education and simulation platform provides virtual reality (VR) simulators as well as feedback on adaptive learning metrics. This allows newcomers to be guided by the right steps and entrenched good habits while allowing more experienced students to pass freely increases the complexity of the simulation.

Psychology Software Tools

The MRI Simulator from Psychology Software Tools (PST) provides a realistic approximation of an actual MRI scanner to allow acclimation and training of participants (and faculty/staff) in a controlled environment for a fraction of the cost of MRI access. The MRI Simulator introduces the participant to an authentic scanning environment, permitting them to gradually become accustomed to the scanning procedure. This particular simulator is less about the software used to take MRI images (see Corsmed above), but rather the logistical motions of MRI medical device training.

The optional MoTrak software uses Ascension Technology’s trakSTAR. The sensor attached to the subject’s head determines the position of the head in space relative to the transmitter. The sensor records angular rotations as well as positional displacements from an initially calibrated position. This information is displayed and logged by the program in real-time, allowing observation of head motion in an MRI simulator. The goal is to monitor how much the participant moves while the scan is in progress. If a participant moves too much, it can potentially result in unusable data and wasted resources.

A mock MRI head coil is also an optional accessory to the MRI Simulator from Psychology Software Tools. Each head coil is keyed to fit securely to the table of the MRI Simulator and includes a head pad for participant comfort. Their head coil products are dimensional representations of the manufacturer’s real head coils. Multiple head coils can be used, as all models are interchangeable.

Simulate the ambient scanner sound and active scanning noise of an MRI Simulator with PST’s SimFx MRI Auditory Simulation Software. Four sound files can be played simultaneously. SimFx also has the capability to accept input from an experimental paradigm which can be used to simulate how the scanner synchronization pulse triggers an experiment.
