WATERLOO, Ontario–(BUSINESS WIRE)- For the first time, practitioners will be able to leverage dual-energy x-ray technology in a portable system. Canadian manufacturer KA Imaging is getting ready to launch Reveal, the world’s first dual-energy x-ray detector that can be taken to the bedside. “Due to infectious nature of COVID-19, bringing patients into a fixed radiology room can sometimes be risky”, explains Amol Karnick, President and CEO of KA Imaging. “Current dual-energy systems are all fixed and Reveal overcomes the limitation of a fixed room by providing a world first portable dual energy solution. Reveal provides radiologists with an unobstructed view of the lungs by removing the bones in an x-ray image”, he continues.

The FDA 510(k) pending detector works with a single exposure. Unlike fixed dual energy solutions, Reveal’s technology enables bone and soft tissue differentiation with no motion artifact. “Our patented technology also allows lateral and oblique dual energy views for the first time”, explains Dr. Karim S Karim, CTO at KA Imaging.

Whereas fixed dual-energy systems can cost as high as half a million dollars, KA Imaging’s Reveal is highly affordable at less than ¼ of this price.

“If a hospital requires dual energy X-ray for COVID-19, you can simply replace any older CR plate or digital fixed or portable detector with Reveal”, says Amol.

Clinical trials

The company is planning clinical trials globally to demonstrate the efficacy of Reveal in triaging COVID-19 and other imaging tasks in the Emergency Room and Intensive Care Units. One of them is expected to begin in Toronto by August. “The world needs affordable and effective portable bedside diagnostics now, and Reveal is a solution that can provide tremendous value for clinicians, hospitals and government”, emphasizes Karim.

Reveal is also being tested on patients with lung cancer. Grand River Hospital (Kitchener, Ontario, Canada) was the first to test the technology. More than 20 patients have been imaged with Reveal, with promising initial results.

ECR

Radiologists globally can learn more about Reveal at the European Congress of Radiology (ECR) from July 15th to 19th. Due to the pandemic, the conference will be held online. KA Imaging is part of the virtual exhibition.

8 Features That Make Reveal Able To Join The Fight against COVID-19

Canadian manufacturer KA Imaging is seeking clinical and government partners for trials

With numbers still climbing, the novel Coronavirus has reached more than 2 million confirmed cases worldwide. As the number of infections gets higher, experts from different fields are trying to find ways to help stop the disease from spreading. In the article “How Reveal’s Technology Can Help Screen For COVID-19”, KA Imaging’s CTO Karim S. Karim says that “recent experiences have shown that testing for viral RNA may not suffice as the only test to confirm or rule out the infection. This is where we can help, as radiological imaging, in some cases, has indicated presence of pulmonary disease even days earlier than PCR testing1. Moreover, radiological imaging can follow the progress of COVID induced pneumonia over time enabling timely decision making about treatment efficacy or need for ventilators”.

The company is in late stage discussions to start clinical trials on the efficacy of Reveal in triaging COVID-19, and actively seeking clinical and government partners to obtain the necessary clinical evidence to determine deployment conditions and to accelerate adoption.

Reveal is undergoing IEC testing and will be submitted to the FDA for US 510K regulatory clearance in 2020.

The following list presents Reveal’s most important features, which could be helpful in the current crisis.

1. Dual-energy subtraction radiography

KA Imaging’s portable Reveal X-ray detector uses dual-energy subtraction radiography, a digital X-ray technique that is widely known for classifying lung nodules for diseases like lung cancer, pneumonia and tuberculosis.

2. One exposure, three images

With one shot, Reveal provides high-quality traditional X-ray, bone subtracted (which is ideal for pulmonary disease diagnosis), and tissue subtracted.

 

3. Motion artifact free

Motion artifacts are streaks due to breathing motion that invalidate images and mislead radiologists. The flaw is possible when using conventional dual energy x-ray systems

4. High DQE = less radiation

Ability to acquire an image with 50X less radiation than CT.

5. Portable

The Reveal detector can be moved to a patient’s bedside or used in the field.

6. Retrofittable

Reveal can be retrofitted into existing X-ray equipment within a few hours. There are 500,000 conventional X-ray systems globally with more than 10,000 installed in Canada even in remote areas.

7. Cost-effective

Conventional dual exposure dual-energy systems can cost as much as half a million dollars and require dedicated rooms. Reveal, on the other hand, has a list price of $125,000 USD.

8. Promising initial results in clinical trial

In October 2018, KA Imaging started a clinical trial at Grand River Hospital in Kitchener, Ontario, Canada to image lung cancer patients with Reveal. The initial results are promising. Watch some of them in the short video below.

Advantages Of Phase Contrast: A Few Examples

inCiTe™ is a world-first phase-contrast benchtop micro-CT. Using KA Imaging patented technology, this x-ray microscope excels at imaging materials that have poor x-ray absorption, such as biomaterials, polymer composites and other low-density samples. inCiTe is also the first commercial micro-CT to utilize BrillianSe™, the highest spatial resolution direct conversion X-ray detector in the world for hard x-rays, that allows for true unmagnified resolution down to 8μm.

Why phase-contrast?

When an object is placed in front of an x-ray source, the shadows, or projections, of the object can be captured by a detector in the background. Computed tomography, also known as CT, is the process of reconstructing an image representation of the object from its x-ray projections using computer algorithms.

The primary advantage of the phase-contrast paradigm is that when an object presents poor conventional absorption-contrast (e.g. soft biological tissue or other low-density materials such as polymers), contrast can instead be generated with higher sensitivity using phase-contrast techniques.

inCiTe™ achieves phase-contrast directly by free-space propagation of the X-ray beam, transforming X-ray phase changes due to the object into X-ray intensity variations at the detector.

The result is an image with much more detail, which wouldn’t be possible using conventional CT techniques.

Watch the video below to see some images and the results of inCiTe.

How Reveal’s Technology Can Help Screen For COVID-19

As the number of infections gets higher, experts from different fields are trying to find ways to help stop the disease from spreading

Picture of Karim S. Karim, CTO at KA Imaging

The latest situation report from WHO points to more than 105,000 confirmed cases globally. As the number of infections gets higher, experts from different fields are trying to find ways to help stop the disease from spreading. In this interview, KA Imaging’s CTO, Karim S. Karim, discusses how Reveal’s technology could strengthen efforts against the spread of the novel Coronavirus. Reveal is undergoing IEC testing and will be submitted to the FDA for US 510K regulatory clearance in 2020.

 

How Reveal’s technology can help diagnose of COVID-19?

Karim: Dual-energy subtraction radiography is widely known for classifying lung nodules for diseases like lung cancer, pneumonia and tuberculosis. Initial studies have demonstrated the improvement of the area-under-the-curve for detecting pneumonia from 0.84 to 0.88 by using the technique1. Thus, the use of dual-energy x-ray in COVID-19 to detect manifestations of the disease in the lungs may contribute to improve diagnosis – especially because Reveal is the only available option that is motion artifact free.

What does “motion artifact free” mean?

Karim: Current dual-energy x-ray implementations are not mainstream because they require acquisition of two X-ray exposures at different energy levels. This double-exposure leads to blurring artifacts due to heart-beating or breathing motion, producing streaks. These artifacts often invalidate the resulting images and force retakes, which is time – and money – consuming. This problem doesn’t happen with Reveal. Our detector uses a patented three-layer sandwich design to acquire images simultaneously from only one exposure. Post-acquisition imaging processing allows the creation of high-quality traditional DR, bone subtracted, and tissue subtracted images. Price also acts like a barrier. A full new dual-energy system can cost as much as half a million dollars, and not many institutions have the resources to invest in this type of high-end technology. Reveal, on the other hand, was designed to be retrofittable. It means that, for a quarter of that price, we can upgrade an existing conventional x-ray system. The install base of all conventional X-ray systems is around 500,000 globally.

Why is early diagnosis so important?

Karim: The World Health Organization says that “early epidemiologic and clinical investigations are critical to carry out early in an outbreak of a new virus”. False negative tests can play an important role in spreading COVID-19, as the patient remains untreated and in contact with others. When the virus is novel, as COVID-19, the challenges are even greater. Recent experiences have shown that testing for viral RNA may not suffice as the only test to confirm or rule out the infection. . This is where we can help, as radiological imaging, in some cases, has indicated presence of pulmonary disease even days earlier than PCR testing2. Moreover, radiological imaging can follow the progress of COVID induced pneumonia over time enabling timely decision making about treatment efficacy or need for ventilators.

What about CT?

Karim: CT is the current clinical reference standard in the detection of pulmonary manifestations of infectious diseases. Though effective, this method suffers from low availability and still exposes patients to high doses of radiation. Even moving the patient to the CT location can represent an extra risk of spreading the virus. The method is undeniably essential but developing alternatives that can increase access and safety is urgent.

What are your next steps?

Karim: A clinical trial comparing conventional X-ray, dual energy X-ray, and computed tomography (CT) is necessary to quantitatively establish the relative performance of all three radiological methods of detecting COVID-19.  KA Imaging is actively seeking clinical and government partners to obtain the necessary clinical evidence to determine deployment conditions and to accelerate adoption.
