Russian scientists unveil innovative Liver Phantom for ultrasound training

RUSSIA—Researchers in Moscow have unveiled a new medical phantom designed to replicate human liver tissue with remarkable accuracy, aiming to enhance sonographers’ training.

This advanced model features realistic anatomical structures, including blood vessels and 18 pathological inclusions such as cysts, tumors, and adenomas.

By producing lifelike ultrasound images, the phantom allows medical professionals to practice procedures in a controlled environment before working with real patients.

This innovation significantly upgrades an earlier liver phantom developed by Moscow scientists, enhancing both realism and functionality.

Twelve different models have been created so far.

Anastasia Rakova, Moscow’s Deputy Mayor for Social Development, emphasized the importance of these phantoms in improving healthcare quality.

 She noted that training on such models boosts doctors’ confidence and precision when performing minimally invasive procedures.

“The latest model enables physicians to practice interventions and distinguish between benign and malignant liver lesions under ultrasound guidance,” Rakova explained.

Researchers at the Center for Diagnostics and Telemedicine developed the new liver phantom under the Moscow Healthcare Department.

Over the past seven years, this center has been at the forefront of creating medical phantoms for radiation diagnostics.

These models are constructed using locally sourced materials like plastic and silicone, with components and molds produced through 3D printing technology.

This approach highlights Russia’s commitment to self-reliance in medical innovation.

Dr. Yuri Vasiliev, Chief Consultant for Radiology at the Moscow Healthcare Department, elaborated on the advancements in this latest model.

 “Previously, our liver phantom replicated only the organ itself. The updated version now includes surrounding soft tissues for more realistic ultrasound imaging,” he explained.

 Additionally, the internal structures have been enhanced with six cysts, tumours, and hyperechoic lesions, enabling doctors to train to identify these conditions and perform procedures like ultrasound-guided biopsies.

Beyond liver models, the Center has developed a wide range of phantoms for training in both ultrasound and MRI techniques.

 These include models of the fetus, breast, thyroid gland, blood vessels, nerves, spine, brain (for transcranial studies), and prostate.

Founded in 1996, the Center for Diagnostics and Telemedicine is a key institution within Moscow’s healthcare system.

It focuses on integrating artificial intelligence into medical practice while advancing radiology research and education.
