Surgeons at Michigan’s Henry Ford Health System successfully treated a patient who suffers from a recurrent brain tumor by delivering a dose of radiation therapy directly on the tumor. This new approach could revolutionize treatment by delaying or preventing future tumor cells from regrowing. Called GammaTile Therapy, the surgically targeted radiation therapy was the first of its kind performed in Michigan; the patient was a 41-year-old male.

Adam Robin, M.D., a neurosurgeon at the Hermelin Brain Tumor Center at Henry Ford, said, “The current standard of care for brain tumors is tumor resection, often followed by radiation, chemotherapy, or a combination of both. Approximately half of patients treated for brain tumors experience tumor recurrence within a year. In his most recent surgery, the patient was treated with a form of surgically targeted radiation therapy, which targets residual tumor cells with radiation before they can significantly replicate. Our hope is this therapy will delay or prevent the tumor cells from replicating and forming a recurrent tumor.”

GammaTile Therapy is cleared by the FDA and designed to delay tumor regrowth while protecting healthy brain tissue in patients who suffer from recurring tumors.

Mira M. Shah, M.D., a radiation oncologist at Henry Ford, external beam radiation therapy is usually delivered no sooner than two- to three weeks after surgery to let the incision heal. With GammaTile, the radiation is focused on specific areas of the brain using a type of brachytherapy (internal radiation) which delivers a therapeutic dose to the tumor during surgery.

Leaving the healthy tissue unharmed, GammaTile maximizes the amount of radiation aimed at the tumor and is critical for those patients who have received external beam radiation therapy, which exposes healthy tissue to radiation.

A bioresorbable, conformable 3D-collaten tile uses uniformly spaced radiation sources to target the tumor cavity after the tumor is removed. In just 33 days, 90 percent of the radiation dose is delivered, and after 100 days, the GammaTiles are considered free from radiation. The placement of GammaTile takes approximately five minutes.

Revolution Ascend, GE Healthcare’s newest workflow, has officially been released. The technology extends clinicians a combination of Artificial Intelligence (AI) meant to automate and simplify otherwise time-consuming tasks. The goal is to deliver more individualized care to patients by freeing up physicians’ time.

The new, wider system can accommodate higher Body Mass Index (BMI) or trauma patients who would otherwise be too challenging to manipulate in a small gantry.

Timothy P. Szczykutowicz, Ph. D., director of clinical operations and the CT Protocol Project at the University of Wisconsin School of Medicine and Public Health, said, “The most time-consuming part of the CT experience isn’t the scan itself, but the steps that fall outside the scan. Within a typical 10 – 30 minute CT exam, the scan itself only takes a few minutes, and the remainder of the time is dedicated to patient prep – including positioning the patient and identifying the correct protocols and settings, plus image reconstruction and report time. Historically, these have been manual processes, putting them at risk of human error; however, AI offers new opportunities to automate workflows and expedite exams with the same or better results.”

The first step in the Revolution Ascend workflow is for the technologist to use an attached bar code reader to scan the patient’s chart. Once scanned, the patient’s information is automatically displayed on-screen, with applicable protocols recommended. Then, the CT technician initiates Auto Positioning, which creates a 3D model of the patient’s body using real-time depth-sensing technology. Auto Positioning also establishes the proper table elevation and cradle movements to ensure the center is in range with the bore’s isocenter. The new Clarity Operator Environment then suggests optimal scan range settings, dosage, and image quality personalized to each person.

Gladys Farias, Imaging Services Manager at Baptist Health in Miami, Florida, said, “Having Revolution Ascend is like having an extra set of hands – which are much needed in today’s healthcare environment. Not only do the system’s intelligent solutions help us expedite exams, but they also enable us to deliver a more comfortable and personalized experience for each patient. Technologists love it for its simplicity. Clinicians love it for its results. And patients love it for its fast exams and comfort.”

Radiologic technicians have been on the front lines of the COVID-19 pandemic more than most people. These technicians have taken a front-seat approach and made a direct impact on the virus outbreak. They work extremely close with coronavirus patients daily, unlike many people throughout the world.

National Radiologic Technology Week (NRTW) marks the centennial celebration for the American Society of Radiologic Technologists (ASRT.) It also exhibits and honors those who perform thousands of X-rays, MRIs, CTs, mammograms, nuclear medicine, cardiac and vascular international, and ultrasound procedures weekly. The vital work of radiologic technologists across the nation are celebrated annually during NRTW. Wilhelm Conrad Röntgen discovered the x-ray on November 8, 1895, which is commemorated by NRTW.

More than 340,000 radiologic technologists have completed chest X-rays, CT scans, and cardiac ultrasounds for COVID-19 patients. These lifesaving procedures have been crucial in detecting and handling virus advancement. When dealing with pandemic patients, proper ventilation placement and ensuring patients receive appropriate care is paramount.

To learn more about NRTW, check out the American Society of Radiologic Technologists website. For more information about purchasing radiologic parts, contact RadParts for all your needs today.

This month big news has hit the medical radiation industry with the partnership between Siemens Healthineers and Varian Medical Systems. Although, according to the German stock market, little change has been observed with Siemens AG, and Varian has made it very clear that Siemens is ready to revolutionize the industry to a new set of standards very soon.

One of the most evident benefits is the strength in adding additional mature products and hardware to the already robust lineup that Varian is well known for in the market. In 2019, Varian’s business held 55% of the global installed base, and with combining the two companies, this move alone will create a product line no other competitor will be able to match. Secondly, the new joint plans will allow for Siemens’ growth to offset the gradual decrease of demand for its imaging modality business (MRI, CT). Lastly, as a company, Varian has grown to a size that, without further investment in operations and new market channels, would not be successful, so this opportunity will allow them to grow and remain steadfast in this sector.

The hardware aspect has gained the most attention with the real jewel being that Siemens possesses its software business, hitting almost $600 million in sales during 2019. Recent plans for Siemens have begun channeling its digital strategy to tap into the most significant challenges that most healthcare providers are struggling with today. This newly formed partnership will allow a radiation therapy linac fleet management system that no other vendor can offer or compete. Read this article to learn more about the three substantial benefits of this merger.

Researchers affiliated with UNIST (Ulsan National Institute of Science and Technology) have demonstrated, for the first time, the ionizing cooling of muons. For those who work in the field, this is considered a massive step toward creating the world’s most powerful particle accelerator. The new muon accelerator is expected to provide a better understanding of the fundamental properties of matter.

The Muon Ionization Cooling Experiment (MICE) collaboration has been behind the breakthrough, including many UK scientists. One of the pioneers is Professor Moses Chung, who leads his team at the School of Natural Sciences at UNIST. His organization’s work has been featured in the online version of Nature on February 5, 2020.

“We have succeeded in realizing muon ionization cooling, one of our greatest challenges associated with developing muon accelerators,” says Professor Chung. “Achievement of this is considered especially important, as it could change the paradigm of developing the Lepton Collider that could replace the Neutrino Factory of the Large Hadron Collider (LHC).”

These experiments have demonstrated that the phase-space volume occupied by the muon beam can be controlled with ionization cooling, as predicted by the field’s theories.

Over the past few years, companies that produce linear accelerators have been focusing on the service and maintenance areas as the primary source of their business plan. Not surprisingly, service contract sales have increased yearly for all linear accelerator companies. As this is beneficial to investors in this space, it doesn’t help the owners of the equipment and medical professionals that use them in their practice.

Many hospitals and clinics are looking for ways to decrease the cost of maintenance and service repairs. The cost of linear accelerator parts and servicing them can get quite pricey, and it can be quite easy to go over-budget very quickly.

This article will break down the main components that will eventually need to be replaced or serviced in the Elekta linear accelerator and will assist those places looking to do their own maintenance. This will help lower the cost of maintenance and allow for more accurate budget forecasting.

Below is the average lifespan of a variety of parts that will eventually need to be serviced or replaced and what you can expect of their overall lifetime value.

Depending on your Elekta linear accelerator, the magnetron has considerably different life expectancy expectations. New magnetrons usually are not equipped with a feedback system, which will need to be replaced with 3-4 years. The 18MV, however, is an older machine that has a feedback system that can last up to 10 years.

The ion chamber of the Elekta part is sensitive to indoor climate and the region in which it is located. High humidity can shorten its lifespan by two-thirds, with a typical chamber lasting within four years and one in higher humidity levels as low as one year.

High use on a linear accelerator can wear on the electron gun and may need to be replaced within a year, but if not used as frequently can last over six years.

The thyratron tube is the part that produces the pulses to the electron gun and is one of the most critical components of any linear accelerator. Surprisingly the thyratron tube has a consistent lifespan regardless of usage. The baseline expectation is three years, with a possible stretch of five years if properly taken care of.

Daily patient volume significantly affects the X-ray tube’s lifespan, and lower levels of usage will allow several years of operation before needing to be replaced.

Newer models of the Elekta linear accelerator include Versa and the Infinity/Axesse. The VersaHD is still relatively new in terms of linear accelerator world, and many of its components still have yet to be determined for life expectancy. However, looking at earlier models can help gauge these expectations.

As with all linear accelerators, usage levels will affect the lifespan of the individual components. The main factors that will affect your parts will be humidity levels, patient loads, and dose rates.

Research from Washington University School of Medicine in St. Louis has found using new mmWave technology to be a great asset to perform precise monitoring of patient motion in real-time during radiotherapy treatments. The mmWave technology can monitor displacements with .1mm to 1 mm accuracy at low cost using a simple and easy to use device. Imaging with millimeter waves can overcome obstacles of current techniques like the optical tracking of a patient’s skin surface or CT scanning. This new device can also monitor breathing and cardiac motion that may, in time, replace respirometers or other breathing monitoring devices. To read more about the research and the outcome of mmWave technology, you can read this article for more information.

In celebration of World Cancer Day on February 4^th, director of IAEA General Rafael Mariano Grossi raised awareness about radiotherapy and how widely used the treatments are throughout the world. He brought to light the fact that 1/3 of lower-to-middle-income countries do not have access to any radiotherapy treatments. A total of 28 countries in Africa do not have a single radiotherapy unit, which makes a cancer diagnosis almost a death sentence for many. It is estimated that 300,000 women die from cervical cancer each year, which needs to stop as this form of cancer can typically be treated and cured in developed countries. The IAEA continues to spread awareness and will establish nuclear and radiation medicine services and provide training to medical professionals to help change these statistics. To learn more, read this article.

Treating cancer can be a long and tedious process with multiple procedures that need to be performed using radiation equipment such as linear accelerators. To become cancer-free, what if this process could be easier? An emerging form of treatment called FLASH radiation therapy treats a cancer patient with a similar amount of radiation normally given over weeks, dispensed at once, within a second of time. FLASH radiotherapy is found to be as effective in killing cancer cells without the continual exposure of radiation to healthy tissue. Researchers at Pennsylvania University are also studying that by changing the type of particle used in the linear accelerator from electrons to protons the treatment will penetrate deeper into the body, essentially making FLASH radiotherapy more effective in treating cancerous tumors.
