Researchers in Moscow have developed a new phantom that accurately mimics human liver tissue, aimed at enhancing the skills of sonographers. The model includes realistic anatomical features, such as blood vessels and 18 pathological inclusions, including cysts, neoplasms, and adenomas. As a result, this phantom produces realistic ultrasound image for training purposes. This latest version is a modified and expanded iteration of a liver phantom previously developed by Moscow scientists, bringing the total number of models created to twelve. This latest development builds upon an earlier liver phantom model created by Moscow scientists, with significant upgrades to improve realism and functionality. To date, 12 such models have been produced. This initiative was reported by Anastasia Rakova, Deputy Mayor of Moscow for Social Development
"Training on phantoms is a key factor in improving the quality of medical care in Moscow. Doctors who practice on these models gain confidence and precision in performing procedures on real patients. The newest model enables physicians to practice minimally invasive interventions and differentiate between benign and malignant liver lesions under ultrasound guidance", - said Anastasia Rakova.
Researchers at the Center for Diagnostics and Telemedicine of the Moscow Healthcare Department have been advancing the development of medical phantoms for radiation diagnostics over the past seven years. These innovative products, designed to mimic human organs and tissues, are constructed using materials such as plastic and silicone, with components and molds fabricated through 3D printing technology. All materials and production methods are sourced locally, showcasing Russia's commitment to self-reliance in medical innovation.
Dr. Yuri Vasilev, Chief Consultant for radiology at the Moscow Healthcare Department, highlighted the advancements in this new model:
"Previously, we created a liver phantom that mimic the organ alone. The updated version now includes surrounding soft tissues for a more realistic ultrasound image," explained Dr. Yuri Vasiliev, Chief Freelance Specialist in Radiation and Instrumental Diagnostics for the Moscow Department of Health. "We also enhanced the internal structures, adding 6 cysts, six tumors, and 6 hyperechoic lesions. This allows doctors to train in identifying these pathologies and performing procedures such as ultrasound-guided biopsy".
In addition to the liver model, the Center has developed a wide array of phantoms for both ultrasound and magnetic resonance imaging (MRI) training. These include models of the fetus, breast, thyroid, blood vessels and nerves, face, lumbosacral spine, and brain (for transcranial studies). For MRI, the team has created phantoms representing the fetus, spine with varying bone density, and prostate.
Founded in 1996, the Center for Diagnostics and Telemedicine is a leading institution within Moscow's healthcare system. It focuses on integrating artificial intelligence into medical practice, advancing radiology, conducting research, and providing education for healthcare professionals.
