The MVM ventilator and 3D PET scanner development arising from basic science work

Area of Science:

• Medical physics
• Biomedical engineering
• Particle physics

Background:

• The COVID-19 pandemic created an urgent need for medical equipment, including ventilators.
• The DarkSide-20k (DS) collaboration, originally focused on dark matter research, pivoted to address this need.
• Existing medical imaging technologies like positron emission tomography (PET) have limitations in resolution and radiation dose.

Purpose of the Study:

• To rapidly develop and manufacture a readily available, low-cost ventilator for severe COVID-19 patients.
• To leverage expertise from particle physics research for advancements in medical technology.
• To enhance positron emission tomography (PET) scanner sensitivity and resolution for improved diagnostics, especially in pediatrics.

Main Methods:

• The DarkSide-20k collaboration repurposed their scientific and engineering expertise.
• Engineers, scientists, and manufacturers collaborated internationally to design and produce the MVM ventilator.
• Innovations in photo-electronics are being applied to develop a new 3D PET scanner.

Main Results:

• 7300 MVM ventilators were manufactured and authorized, delivered to the Canadian government.
• The ventilators are being considered for donation to countries facing urgent needs.
• Development of a more sensitive 3D PET scanner with potential for reduced radiation doses and better resolution is underway.

Conclusions:

• The DarkSide-20k collaboration demonstrated adaptability by contributing critical medical equipment during a global health crisis.
• The project highlights the potential for interdisciplinary collaboration between fundamental science research and medical technology development.
• Advancements in PET scanner technology promise improved diagnostic capabilities and patient care, particularly for pediatric applications.
