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.

Why Scatter Radiation Matters in C-Arm Fluoroscopy

In fluoroscopy, X-rays interact with the patient’s tissues, generating secondary scatter rays that reflect toward the operator. The closer a person stands to the C-arm, the higher the cumulative exposure. Studies have shown that scatter levels can reach several hundred microsieverts per hour near the operator’s hands during orthopedic procedures. During C-arm fluoroscopy, every image produced also generates invisible scatter radiation. This secondary radiation spreads around the operator — especially hands and arms — and can accumulate over years of repeated exposure. While modern imaging prioritizes patient protection, the safety of medical professionals is equally vital. Without proper protection, the people who guide every precise movement under the C-arm face unnecessary risk. Recognizing this risk is only the first step. Real improvement begins with action — using dedicated solutions designed to reduce scatter radiation without disrupting daily workflow. Certified tools su...

An External Way to Reduce Scatter Radiation — Without Interfering With Your C-arm Workflow

 C-arm image quality is established by the device and by the clinical decisions made during each procedure. Our role is not to adjust, replace, or reinterpret those parameters. Instead, we focus on a different part of the environment: The scattered radiation moves outward toward the operator. This portion of radiation is not needed for diagnosis, yet it contributes to long-term occupational exposure. Our external filter is designed to reduce that specific component — working alongside your current setup, not inside it. Works outside the imaging chain The filter attaches externally and functions independently of: kVp or mA settings detector sensitivity contrast or density adjustments device brand or model Once it's set, Clinical teams continue using their established imaging routines. The filter simply operates in the surrounding space where scatter is generated. Designed to maintain your clinical workflow No additional steps. No software. No recalibration....

Reduce C-arm Scattered Radiation Before It Reaches You

 Scatter radiation in C-arm fluoroscopy has long been treated like background noise—always there, rarely questioned. But in reality, it shapes the exposure environment of every operating room. This isn’t a problem of machine performance or operator technique. It is, at its core, a geometry problem , expanding through space before PPE ever has a chance to block it. When the primary beam passes through the patient, it immediately transforms into multi-directional scatter. The pattern never changes. Longer fluoroscopy time means more scatter. Angle variations widen the spread. And the operator’s hands, eyes, and thyroid often sit closer to the field than any other part of the body, collecting dose simply because of proximity. This is why PPE alone can’t solve the issue. Lead aprons, thyroid shields, and gloves protect the body—but only after scatter reaches it . By the time PPE steps in, scatter has already expanded into the room, filling the operating space with exposure that acc...
