One Engineer’s Quest to Cut Medical Radiation in Half

When we think about life-saving medical care, we often imagine skilled surgeons, advanced technology, and high-tech operating rooms. But inside every surgical suite, there is an invisible, silent workhorse operating in the background: the C-Arm X-ray system.

While C-Arm devices provide essential real-time imaging during complex procedures, they also present an unavoidable challenge—invisible, cumulative radiation exposure. Day after day, surgeons and nurses work alongside these machines, absorbing doses of direct beams and scattered radiation that quietly accumulate over a career.




A Question Born in the Operating Room

Before founding MSLINEENG, Biomedical Engineer Jae-Sang Ham spent over a decade working directly in hospital environments alongside mobile X-ray equipment.

During those years, he repeatedly witnessed a troubling reality. In fast-paced, high-pressure operating rooms, medical personnel could not always wear heavy lead aprons comfortably or cover every part of their bodies. Over time, low-dose scattered radiation poses genuine long-term health risks to the very people dedicated to saving lives.

Seeing this firsthand led to a single, persistent question: "Can we protect medical staff and patients at the source, without disrupting the surgical workflow?"


The Breakthrough with KICET

Driven by this mission, Ham set out to find a solution that wouldn't just block radiation, but optimize it.

Blocking X-rays is simple—heavy metals like lead do it easily. The real challenge, however, was doing so without degrading X-ray image contrast. If an image becomes blurry, a surgeon cannot diagnose or operate accurately.

To solve this dilemma, MSLINEENG partnered with the Korea Institute of Ceramic Engineering & Technology (KICET) on a specialized R&D initiative. Together, they developed a proprietary composite ceramic material formulation designed to filter out useless, high-exposure soft X-rays and scattered radiation while allowing vital diagnostic imaging rays to pass through clearly.

The result was the CVP-2 Radiation Reduction Filter—a smart, compact filter attached directly to the X-ray tube housing. Armed with this technology and a mission to transform medical safety, MSLINEENG Co., Ltd. was officially established in 2011.


Protecting Healthcare Workers Worldwide

Introducing a new safety innovation into established medical workflows required rigorous, objective proof.

Clinical studies conducted in collaboration with researchers at Seoul National University Bundang Hospital demonstrated significant radiation reduction without loss of image contrast—findings later published in the peer-reviewed SCI journal, Journal of Radiological Protection.

With global certifications including FDA registration, CE mark, KFDA approval, and ISO standards, CVP-2 filters quickly expanded beyond local clinics. Today, MSLINEENG’s filters are installed in operating rooms and pain management centers across over 12 countries, actively lowering daily exposure levels for healthcare teams.


A Continuing Mission for Safer Care

MSLINEENG continues to expand its ceramic filtering technology beyond C-Arm devices to mobile X-rays, angiography systems, and other radiation-emitting medical equipment.

"Our mission is simple: to safeguard the people who heal others."

By turning years of dedicated research into practical, life-saving solutions, MSLINEENG is quietly transforming operating rooms into safer spaces—ensuring that those who care for our health are protected as well.

Reducing Radiation Exposure in C-Arm Procedures with the CVP-2 Filter

  Every day in operating rooms around the world, doctors and staff stand beside patients, focusing only on one thing: helping them heal. But while patients are usually exposed to radiation just once during a procedure, the healthcare team is there all day, every day — and that means radiation quietly builds up inside their bodies over time. C-arm is an essential imaging tool for modern surgery. But with it comes an invisible risk. The Hidden Risks of C-Arm Radiation Think about this: A single CT scan can expose a patient to over 13 times the annual radiation dose limit allowed for the general public. If a physician’s hand is exposed to C-arm X-rays for just 12 minutes and 30 seconds , it can already reach the yearly limit set for extremities. Radiation doesn’t leave immediate marks. There are no burns, no pain signals. It accumulates silently — and health problems may appear years later. That’s why reducing exposure isn’t optional. It’s essential. Why Lead Aprons A...

Safer Dental Imaging for Patients and Clinicians: Meet the DTG Filter

 Dental X-rays are among the most common imaging procedures worldwide. From routine check-ups to orthodontic planning and implant treatment, patients—especially children and adolescents—often undergo multiple X-ray exposures throughout their lives. While each exposure may seem minimal, the cumulative effect is something we cannot ignore. In many clinics, patients are protected with a thyroid collar or a lead apron. These are important and effective, but they primarily shield against direct beams. Scatter radiation, which spreads into the surrounding environment, remains a hidden risk that standard protective gear alone cannot fully address. This is where the DTG Filter comes in. Specifically designed for dental X-ray units, the DTG filter reduces unnecessary scatter radiation while maintaining high-quality diagnostic images. It offers: Improved safety for patients, particularly children who may require repeated imaging. Peace of mind for dental professionals working close ...

Pioneering Radiation Reduction Filters for a Safer Medical Environment

Radiation has played a vital role in modern medicine for many years, but it doesn't come without dangers. Healthcare professionals—doctors, nurses, and radiologic staff—are exposed to scatter radiation daily while treating patients. At MSLINEENG, we identified this issue early and proudly became the first in the world to introduce an X-ray radiation reduction filter for hospitals, raising the bar for safety in medical settings. Our Product Line CVP-2: C-arm Radiation Reduction Filter Specially engineered for C-arm X-ray machines, the CVP-2 is trusted by more than 1,000 hospitals across the country. Featuring patented filter technology, it reduces harmful scatter radiation while preserving image clarity, offering vital protection for surgeons and medical teams during demanding procedures. DTG: Dental Radiation Reduction Filter Dental professionals often work extremely close to X-ray sources. The DTG filter is designed specifically for dental imaging, significantly cutting down on...
