This is a hologram of a fracture from a computed tomography (CT) scan displayed by the start up company Voxon at the 2019 Radiological Society Of North America (RSNA) meeting. The technology uses a half millimeter thick glass plate that pulses up and down very rapidly while projecting 4,000 images per second. It can display standard DICOM radiology files or STL files used for 3-D printing.

There were at least four vendors showing holographic screens to display advanced visualization 3-D renderings of anatomy from medical imaging. All four of these screens could be viewed in true 3-D using normal vision without the need for special glasses or a virtual reality visor.

The images in this example flickers because of the different frame rates of the system and the iPhone used to film it, but the actual images appears much more stable.

Kevin Little, Ph.D., assistant professor and medical physicist, Department of Radiology, at The Ohio State University, explains how hospitals can better manage their computed tomography (CT) imaging protocols across their fleet of CT scanners from various vendors. He moderated a session on this topic at the 2019 Radiological Society of North America (RSNA) meeting.

He stressed the importance of CT protocol management to an imaging practice and showed examples of tools that can be used to develop consistent protocols across multiple systems. Little said it is important to develop awareness of the Management of Acquisition Profiles (MAP) IHE profile and features that should be requested from CT scanner vendors.

CT protocols, which include all clinical and technical parameters for a given study, are the starting point for achieving high-quality images with reasonable radiation and contrast doses. An imaging practice that desires to follow the "as low as reasonably achievable” (ALARA) principle and produce high-quality images should have standardized protocols across their enterprise. Accreditation standards require a periodic review of all scanner protocols. However, variations among vendors, models, and clinical indications mean that managing and optimizing dozens of parameters for each protocol on every scanner in a health system is challenging. Even when variations between systems are limited, managing protocol names and parameters across multiple systems can be difficult. The purpose of this symposium is to identify tools and techniques that may be used to manage protocols across multiple systems and to provide a framework for protocol optimization.

Mahadevappa Mahesh, Ph.D., chief of medical physicist and professor of radiology and medical physics, Johns Hopkins University, Baltimore, treasurer of the American Association of Physicists in Medicine (AAPM),a board member of the American College of Radiology (ACR), presented a late-breaking study on how medical imaging radiation dose has started to drop over the past decade. He is the co-chair of the National Council on Radiation Protection and Measures Report (NCRP), and presented the most recent NCRP data analysis at the 2019 Radiological Society of North America (RSNA) meeting.

The new NCRP 184 report covers the period between 2006 and 2016, the period of the most current CMS data. It shows a decrease of about 20 percent in the radiation dose the U.S. population receives from medical imaging, compared to the NCRP 160 that covered the period of up to 2006.

Key findings of the study include:

   • CT dose dropped about 6 percent, despite a 20 percent increase CT scans since 2006;

   • Drop of more than 50 percent for nuclear imaging scans, mainly due to fewer procedures being performed;

   • A 15-20 percent decrease across X-ray imaging modalities.

Mahesh says this shows the impact of using "as low as reasonably achievable" (ALARA) principals, new dose guidelines outlined jointly by numerous medical societies, and dose reduction initiatives like Image Wisely, Image Gently, and the American College of Radiology (ACR) Dose Index Registry.

He said there was growing concern a decade ago when the last council report was published, which showed a steep increase in radiation dose. This was mainly due to a rapid increase in the use of computed tomography (CT) and other types of X-ray based and nuclear radiotracer medical imaging. This prompted the ACR to create the Image Wisely program and push for the use of more thoughtful imaging doses based on patient size, using the "as low as reasonably achievable” (ALARA) principle. While CT dose was lowered, he said the biggest decline over all was in nuclear imaging.

David Sjostrom, Ph.D., deputy chief physicist, Herlev Hospital, Department of Oncology, Division of Radiotherapy, Herlev, Denmark, shares the first clinical experience treating cancer patients with the Varian Ethos radiation therapy system. He spoke to ITN at ASTRO 2019, where he presented information on the first 5 patients in the world being treated with this new technology. It uses artificial intelligence to take the onboard cone beam CT scans to automatically create an adaptive plan for any changes in patient weight loss, bladder volume, or change in tumor size. The plan can be available in minutes while the patient is on the table. It enables sparing of more healthy tissue and makes adaptive therapy much easier to use. 

Kristin Higgins, M.D., medical director of radiation oncology, Emory Clinic at the Winship Cancer Institute, explains considerations when treating previous radiation oncology patients again at the same or other tumor sites. She spoke on this topic at the American Society for Radiation Oncology (ASTRO) 2019 annual meeting in Chicago.

Candice Johnstone, M.D., MPH, Medical College of Wisconsin explains the need for palliative radiotherapy and patient selection considerations at the American Society for Radiation Oncology (ASTRO) 2019 annual meeting. 

Despite improvements in the survival of some populations of cancer patients, some patients are not candidates for ablative therapy and need symptom relief. Cases will be used to highlight evidenced based approaches to palliative radiation therapy. A significant proportion of patients do not benefit from immunotherapy and need standard palliative radiation. The best palliative radiation utilizes the fewest number of fractions to achieve the desired effect, minimizes side effects of treatment and treatment related costs.

Anne Hubbard, MBA, director of health policy for ASTRO, explains the details and purpose of the proposed Radiation Oncology Alternative Payment Model (RO Model) at the ASTRO 2019 meeting.

In July 2019, the Center for Medicare and Medicaid Innovation (CMMI) issued a proposed rule establishing the RO Model. It requires participation from about 40 percent of radiation oncology practices in a model that dramatically changes the way Medicare pays for radiation therapy services. The RO Model is designed to test whether prospective episode-based payments to physician group practices (PGPs), hospital outpatient departments (HOPDs) and freestanding radiation therapy centers for episodes of care would reduce Medicare expenditures while preserving or enhancing the quality of care for Medicare beneficiaries. CMMI proposes launching the model as early as Jan. 1, 2020.

This is a quick demonstration of the Varian Identify image-guided patient positioning system at the American Association of Physicists in Medicine (AAPM) 2019 meeting. It helps align patients on the radiotherapy system treatment table to match the position they were in when the computed tomography (CT) scan was created. This ensures the radiation beams are delivered according to the treatment plan and will not be aimed accidentally at health tissue. It uses real-time tracking of the surface of the patient's skin using three visible light emitters, so it does not add dose, such as when on-board X-ray imaging is used. The system compares the patients position to the treatment plan CT scan and color codes in red any areas that are not in the proper position. It also uses RFID tags on the table to help know the exact position of the patient.

The system can show the radiotherapist if the patient is no longer aligned with the plan and the therapist can manually stop the therapy. The vendor said in the future, they plan to integrate the system with Varian's therapy systems so treatment will be stopped automatically by the Identify system. 

The system also uses a biometric scanner to ensure the correct plan is being used with the correct patient.
