Moscow scientists present 14 realistic anatomical phantoms for medical training

RUSSIA—Moscow has expanded its cutting-edge medical training infrastructure with two groundbreaking anatomical phantoms: a multi-layered stomach model and a pulsating arterial vessel simulator.

Doctors now use these highly realistic training tools to master complex surgical procedures, refine ultrasound diagnostic techniques, and verify the accuracy of CT and MRI imaging equipment.

Anastasia Rakova, Deputy Mayor of Moscow for Social Development, confirmed that Moscow scientists have developed 14 sophisticated anatomical models to date, serving dual purposes of advanced medical training and precise diagnostic equipment calibration.

Innovation Driving Medical Education

Moscow continues to integrate innovative technologies not only to enhance diagnostic and treatment capabilities but also to revolutionize how physicians receive training.

The development of anatomical phantoms represents a significant milestone in this initiative.

These precise models replicate the unique properties and characteristics of human tissue and physiology, providing clinicians with essential tools to practice ultrasound diagnostics, assess CT and MRI scan quality, and perfect their techniques for intricate medical procedures.

The Multi-Layered Stomach Phantom

The stomach phantom features a hollow organ design with a five-layer wall structure.

Each layer possesses distinct ultrasonic reflectance properties that generate imaging results nearly identical to those obtained from an actual human stomach.

The innermost layer mimics the gastric mucosa with a realistically folded anatomical structure.

Scientists embedded models of tumors at varying depths within these layers, making the phantom an invaluable resource for practicing endoscopy, mastering ultrasound diagnostics, and perfecting biopsy techniques.

During simulated ultrasound-guided gastric biopsies, clinicians must precisely navigate needles into targeted layers to reach simulated tumors.

Since each wall layer measures only one to three millimeters thick, the procedure demands exceptional accuracy to avoid puncturing incorrect layers or penetrating entirely through the organ wall.

The Pulsating Arterial Vessel Simulator

The pulsating arterial vessel phantom functions as a dynamic model that mimics precise pulse waves within specific blood vessel sections.

This advanced simulator comprises two core components: an abdominal aorta model and a specialized device generating realistic pulse waves.

Medical professionals use this platform to refine computed tomography angiography protocols while surgeons practice essential vascular surgery techniques.

This training proves critical because accidental injury to major arteries remains a potential complication during complex spinal or abdominal procedures.

Surgeons must meticulously avoid piercing arterial walls, and the phantom provides a safe environment to develop this vital skill.

Expert Perspective on Training Impact

Anton Vladzimirsky, who holds both a Ph.D. in Medicine and a D.Sc., serves as Deputy Director for Research and Development at the Center for Diagnostics and Telemedicine of the Moscow Healthcare Department.

He emphasized that medical phantom creation exemplifies how scientific innovation directly enhances clinical training quality and subsequently elevates patient care standards.

Vladzimirsky explained that the stomach phantom allows clinicians to practice multiple essential skills simultaneously, from ultrasound diagnostics to tissue sampling.

Given current statistics on gastrointestinal diseases, all measures improving diagnostic and treatment quality carry paramount importance.

The pulsating arterial vessel phantom enables physicians to observe differences between normal and pathological pulsation through visual, tactile, and CT-based examination. Irregular or intensified pulses can signal aneurysms, which represent life-threatening conditions that physicians must recognize flawlessly.

Seven Years of Development Excellence

The Center for Diagnostics and Telemedicine operates as a leading research and practical institution within the Moscow Healthcare Department.

The organization coordinates radiation and instrumental diagnostics departments, drives digital healthcare transformation, integrates artificial intelligence technologies into clinical practice, conducts scientific research, and provides specialized medical professional training.

Scientists at the Center’s laboratory have dedicated more than seven years to developing medical phantoms.

This extensive experience enabled them to establish MosMedMaterial, Russia’s first comprehensive database of tissue-mimicking materials specifically engineered for radiation diagnostics.

The repository catalogues 23 solid materials and 19 liquid materials formulated for creating specialized medical phantoms used in ultrasound, computed tomography, and magnetic resonance imaging applications.
