Radiation Safety

ALARA component for all clinical modules

The Mentice Radiation Safety software module is designed for physicians, nurses, and technicians who use interventional fluoroscopy equipment.

Radiation carries with it serious risks both to the medical team and the patient. The incidence of lens opacities after several years of work in a cath lab can be up to 40-50%, and unintended use of extreme doses to patients can cause life-changing injuries. Learning proper radiation reduction techniques is therefore critical for all interventional procedures. 

This Mentice unique solution increases the value of the procedural training by adding a hands-on ALARA (as low as reasonably achievable) component to all of the user’s installed training modules. The plug-in assumes some familiarity with interventional fluoroscopy and the basic principles of ionizing radiation.

An evidence-based radiation model takes into account the patient anatomy, C-arm geometry and operator-controlled settings, and dynamically calculates realistic air kerma, KAP, ESD and PSD readings. The delivered dose affects the degree of noise on the fluoroscopy x-ray image, which opens for training on how to best manage difficult imaging situations

Furthermore, a number of instructive visual heatmaps with live information on current dose distributions are displayed, both for patient skin dose and for scattered radiation to the operator and team. Together with many other advanced functionalities, such as estimation of eye doses, the plug-in lets the trainee optimize his or her own radiation reduction skills under highly realistic conditions, but in a completely radiation-free environment.

The ability to remotely introduce complications in real-time while trainees are performing a procedure on the Mentice simulator tremendously enhances the learning experience and brings simulation even closer to reality.
