CurveBeam’s pedCAT Imaging System Exhibited at CIRMS Annual Meeting

The Council on Ionizing Radiation Measurements and Standards (CIRMS) 25th Annual Meeting in Gaithersburg, MD will showcase new cutting edge technologies touching on the fundamental aspects of radiation measurements and focusing on the theme of ‘Past, Present, and Future’. The dynamic and diverse aspects of the importance of measurements and standards in this area will be addressed by international experts from academia, industry, and government. These experts will examine radiation protection, industrial applications and radiation effects, medical applications, homeland security, and other related areas.

CurveBeam is pleased to announce we will be participating. A CurveBeam engineer will be presenting on Tuesday, March 28 during “Breakout Session III: Real Time Imaging for Orthopedic Applications.” Her talk is titled “Why Cone Beam CT Can Make 3D the Standard of Care in Extremity Imaging.” With Cone Beam CT imaging, CurveBeam is revolutionizing the way specialists diagnose and create comprehensive treatment plans for podiatric and orthopedic issues.

The core team behind CurveBeam pioneered Cone Beam CT imaging technology for the dental specialties. The introduction of point-of-care Cone Beam CT imaging revolutionized the industry and ushered in the advent of custom dental implants and improved practices in orthodontics and oral surgery. Today, Cone Beam CT scans are virtually the standard of care for advanced oral surgery treatment planning. In the same way, CurveBeam hopes to contribute to the improvement of the orthopedic and podiatric specialties worldwide through their new product pedCAT.

One of the goals of the CIRMS Annual Meeting is to get input from audience participants on the need for developing a 3D real-time imaging tool for evaluating orthotics inside shoes with the patient in a weight bearing position. Once the orthotic has been made, an image of the patient can be taken in the weight bearing position, with the patient standing in his/her shoes with the new orthotic installed in the shoe. This type of analysis could be used to evaluate if the orthotic does what it is meant to do. The 3D weight bearing images can provide information about specific bone alignment issues using the new orthotics. The images can also reveal if the new orthotic is providing the expected amount of correction without compromising other foot anatomical issues, and if the spacing between the major foot joints is affected by the new orthotic.

CurveBeams’s pedCAT system allows specialists a unique bilateral, weight bearing 3-dimensional view of the foot and ankle to fully diagnose and create comprehensive treatment plans. The pedCAT is a compact, ultra-low dose CT imaging system ideal for orthopedic and podiatric clinics. Patients benefit from the convenience of point-of-care advanced diagnostic imaging. Scan time is one minute, and the pedCAT automatically generates all standard X-Ray views in addition to the full CT volume. Depending on the scan protocol, the patient is exposed to 2 – 5 micro Sieverts per scan. That’s about the same as a plain X-Ray study of the foot and ankle, and less than the average daily background radiation a U.S. resident is exposed to.

CBCT Technology is Increasingly Used by Orthopedists and Podiatrists

Cone beam computed topography (CBCT) systems are becoming popular with orthopedists and podiatrists because they quickly provide high-quality, low-dose, 3D imaging of musculoskeletal conditions. Dentists and podiatrists have been using CBCT technology for years, but the pedCAT by CurveBeam is designed specifically for extremities: especially knees, ankles, and feet. This compact, affordable unit gives specialists bilateral, weight-bearing 3D views of the foot and ankle, allowing physicians to create comprehensive treatment plans. In a Radiology Today article titled “Imaging in the Extremities,” Beth W. Orenstein, a freelance medical writer, examines this new technology.

There are a number of advantages to these new compact CBCT units. First, they have a larger area detector by which to image the patient in a single rotation, rather than taking many slices as with a tradition CT scanner. This feature eases system operation and reduces scan time. The pedCAT, for example, scans a patient in about one minute. Second, CBCT units can be located outside radiology departments, since they typically don’t require a lead-lined room or a special power source. Third, providers will find that CBCT positively impacts their practice, with improved diagnostic capabilities, streamlined workflow, and greater productivity. Finally, patients benefit with an easy-access unit that provides same-day results from a single brief visit.

CBCT provides other benefits to orthopedists and podiatrists, as well, such as the ability to produce load-bearing images. Load-bearing images of extremities, such as feet and ankles, may reveal alignment abnormalities that a conventional CT scan might miss. And CBCT offers improved spatial resolution over other methods, such as traditional CT scans or X-rays. One of the biggest benefits, though, is the transmission of a far smaller radiation dose. The tube current on a conventional CT scan typically ranges between 50 mA and 300 mA, and even an ultralow-dose setting would be between 20 mA and 60 mA. CurveBeam’s pedCAT, by contrast, has a fixed tube current of just 3mA, and the patient is exposed to 2 to 5 micro Sieverts per scan—less than the average background radiation a U.S. resident experiences daily.

Of course, there are also several challenges in adopting CPCT technology. For example, since CBCT uses a completely different image acquisition technology, comparing scans with conventional CT is difficult. The lack of dose and image quality assessment standards for CBCT limits accreditation. And since a unit like the pedCAT automatically generates all standard X-Ray views in addition to the full CT volume, many orthopedists and podiatrists feel they can interpret the images themselves in-house. In fact, some radiologists fear that point-of-care units could negatively impact their role as specialists. But other radiologists argue that the sophistication required in interpreting CT scan results will keep their expert services in demand.

In the future, CBCT units may even be used in emergency departments, as well, since the unit takes up so little space. The pedCAT’s footprint, for example, is about four feet by five feet. This means a CPCT scanner could be easily relocated where needed since it is relatively lightweight and mobile.

The Hospital for Special Surgery Utilization of pedCAT

The Hospital for Special Surgery (HSS) located in Manhattan is ranked as the #1 hospital for orthopedics by the prestigious US News and World Report (2016-2017). And when the surgeons and clinicians at this elite medical institution need to make a proper foot and ankle diagnosis, they rely on CurveBeam’s revolutionary pedCAT system for fast and accurate 3D imaging.

Assessing the root cause of a patient’s pain is essential for developing a comprehensive treatment plan. At HSS, this evaluation process begins with an interview so that specialists can learn a patient’s unique history and obtain information regarding the primary care physician’s prognosis. Then the patient steps into the pedCAT scanner, where expert radiologists can conduct foot and ankle imaging faster than X-rays and CT scans, resulting in fewer hospital trips and significantly reduced exposure to radiation. The pedCAT system delivers the highest quality images and robust data, allowing physicians to make the most accurate diagnosis of the malady, and guiding the surgeon in the operating room for a superior treatment outcome.

Join The TALAS Revolution in Foot and Ankle Diagnosis

For years, Dr. François Lintz, an orthopedic foot & ankle surgeon at Clinique de l’Union in Toulouse, France, relied on 2D (weight-bearing) X-rays and 3D (non-weightbearing) CT scans in treating patients, some with extraordinarily complicated deformities. Because of the shortcomings of the images, the doctor had to rely on his eyes and hands to calculate alignment measurements. The combination of the rudimentary tools and his expertise allowed him to successfully correct many malformations, although for reasons unknown, a fraction of patients did not experience positive treatment outcomes.

In order to minimize these unsuccessful treatment outcomes, Dr. Lintz searched for more advanced imaging tools and found CurveBeam’s pedCAT. pedCAT provides bilateral, weight bearing 3D CT imaging of the foot and ankle. Dr. Lintz quickly discovered that pedCAT greatly surpassed traditional imaging methods. pedCAT technology proved to be ten times faster than X-Ray and CT studies, reduced the number of patient trips to the hospital, and exposed patients to significantly less radiation.

Dr. Lintz also realized the 3D data generated by pedCAT was far more robust than could be interpreted by available software for making foot alignment measurements. So he embarked on a collaboration with CurveBeam engineers to develop a revolutionary new measurement software – TALAS.

TALAS Software demonstration of 3DWBCT hindfoot alignment measure

 

TALAS (Torque Ankle Lever Arm System) is a groundbreaking feature within pedCAT’s visualization application CubeVue. Currently only applicable for hindfoot alignment with forefoot alignment coming soon, TALAS automatically determines foot and ankle offset in a 3D volume. While not approved as a diagnostic tool in humans, TALAS can be used in research for establishing a 3D database of important anatomical landmarks for future diagnostic use. TALAS is patent pending.

Using TALAS to conduct his own research, Dr. Lintz compared the correlations of 3D and 2D biometrics of hindfoot alignment with actual alignment. What he discovered was a 20% greater correlation with actual alignment using pedCAT’s 3D imaging and TALAS feature. pedCAT outperforms radiographs and non-weightbearing CT scans in detecting correct angles, helping to prevent inaccuracies of projection and foot orientation. And TALAS utilizes this wealth of data to provide remarkably precise measurements.

The innovative features of the TALAS Software

TALAS is the only tool available dedicated to measure hindfoot alignment with a weight bearing 3D dataset. While presently useful for research, Dr. Lintz hopes clinicians around the world will use the software feature to help build a comprehensive database of (anonymized) information, which will allow TALAS to one day serve in diagnosis. Quantifying deformities is the first step to helping medical experts develop treatment plans to correct them. You’re invited to join the data harvesting effort by utilizing TALAS in order to create more positive outcomes for your current, and future, patients.
