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.

Radiation Oncology | September 20, 2019

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.

Treatment Planning | August 21, 2019

This is an example of the Mirada DLCExpert deep learning software that automatically identifies organs, segments and auto-contours them as the first step in creating radiation oncology treatment plans. This example of a segmented prostate computed tomography (CT) scan being used to plan radiotherapy was created without any human intervention. It was demonstrated at the American Association of Physicists in Medicine (AAPM) 2019 meeting. 

This example shows OAR Space hydrogel (outlined in blue) injected to create space between the prostate and the rectum to prevent damage to that radiation sensitive structure. The gel is hard to identify on the CT scan because it looks like part of the rectum or prostate. But the softwares AI has been trained to identify it when present.

The DLCExpert software was cleared by the FDA in July 2018 and was first shown at ASTRO 2018. It automatically identifies anatomical structures and contours them to save staff time. The files created by the software are vendor neutral and can be imported into any vendor’s treatment planning system. Read more about this software.

Patient Positioning Radiation Therapy | August 21, 2019

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.

Treatment Planning | August 21, 2019

This is a lung cancer tumor radiotherapy treatment plan for the Accuray CyberKnife system demonstrated at the American Association of Physicists in Medicine (AAPM) 2019 meeting. The blue lines are the radiation beam lines that are shot from different positions to all intersect in the tumor to deliver the prescribed amount of radiation and prevent damage to surrounding healthy tissue. The beams also are planned around the critical structure organs near the target tumor to limit their dose. The organs are color coded to differentiate them on the treatment plan and to help with the estimated radiation dose each receives based on the plan. After the plan is optimized, it is fed into the radiotherapy treatment system computer to deliver the treatment once the patient is positioned on the treatment table exactly as they are in the CT scans used to create the plan.

Computed Tomography (CT) | August 21, 2019

This is a quick walk around of a mobile 32-slice computed tomography (CT) scanner used for surgery, brachytherapy and proton therapy on display by Mobius Imaging at the 2019 American Association Of Physicists in Medicine (AAPM) meeting. The system simply plugs into a standard wall outlet and all of the required hardware and software is built into the gantry. There is no need for an equipment closet, cabinet or server tower. The company said the CT system was created by some of the same developers who built the O-arm mobile CT system, but they said this CT scanner is much more compact.

 

Radiographic Fluoroscopy (RF) | August 09, 2019

Shimadzu displayed the FluoroSpeed X1 conventional radiographic fluoroscopy (RF) system at the Association for Medical Imaging Management (AHRA) 2019 meeting in July. The system was pending U.S. Food and Drug Administration (FDA) approval at AHRA, but received FDA 510(k) clearance in early August 2019.

The system features a 33-inch aperture, large enough to place a wheelchair inside. It can be rotated 90 degrees in either direction and the deck can be parked in any position, making it easier for patients to get on and off the 660-pound weight table. The FluoroSpeed X1 offers controls that are ergonomic for technologists, with duplicate controls on each side for either a left- or right-handed tech. The machine also has a large aperture to allow swallow studies.

The FluoroSpeed X1 comes equipped with a 17 x 17-inch dynamic digital X-ray detector (FPD) in the table bucky, allowing it to both be used for fluoroscopy as well as radiographic exams.

CT Angiography (CTA) | August 07, 2019

This is a quick walk around of the new Siemens Somatom Go.top cardiovascular edition compact computed tomography (CT) scanner on display at the Society Of Cardiovascular Computed Tomography (SCCT) 2019 meeting in July. It is aimed at cardiology office based imaging and was released this past spring at the American College of Cardiology (ACC) meeting.

The system has removable tablets on each side of the scanner where the tech can adjust the machine, review scout scans and trigger the scanner. The idea is to improve workflow and allow the tech to remain at the bedside longer to be with the patient, rather tucked away in a remote control room using an intercom.

The entire system is built into the gantry seen here, so there is no need for extra equipment in a closet, cabinet or server tower.

It comes in a 128 slice configuration with 4 cm of anatomical coverage per rotation.

It uses the Stellar detector and tin filtration to eliminate low energy photons and help lower dose. It can be programmed to aid workflow by automatically removing bone, create cured planar reconstructions, lung CAD and other post-processing features so more time can be spent on reading scans. The scanner also comes with a HeartFlow FFR-CT starter pack.

Sudhen Desai, M.D., FSIR, interventional radiologist at Texas Children's Hospital, editor of IR Quarterly for the Society of Interventional Radiology (SIR) and on the Board of Directors for the Society of Physician Entrepreneurs, explained how artificial intelligence (AI) can assist in pediatric imaging and the pitfalls of training AI systems. He spoke at the 2019 Radiology AIMed conference

Deep learning algorithms require large amounts of patient case data to train the systems to read medical images automatically without human intervention. However, in pediatrics, there are often much lower numbers of normal and abnormal scans that can be used compared to vast amounts of adult exams available. This makes it difficult to train systems, so AI developers are coming up with innovative new ways to train their software. Compounding issues with training pediatric imaging AI is that the normal ranges change very quickly for young children due to their rapid development. He explained what is normal for a 2-year-old may not be normal for a 5-year-old.

Desai and other pediatric physicians who spoke at the conference said AI could have a big impact on pediatric imaging where there are not enough specialists for the increasing image volumes.

Digital Radiography (DR) | May 20, 2019

This is a quick walk-around video showing the Siemens Healthineers Multix Impact digital radiography (DR) room X-ray system at RSNA 2018. The system offers an intuitive operating system to help improve productivity. The in-room touch user interface on the tube allows the technologist to remain at the patient’s side. And when unable to be at the patient’s side, the technologist is able to monitor and optimize positioning from the control room via the system’s patient positioning camera, potentially reducing repeat imaging and unnecessary patient dose. Lights at the top of the X-ray system automatically indicate it the patient anatomy is aligned properly with the exam type the technologist chose for optimal imaging to reduce the need for retakes. 

The Multix Impact also offers an intuitive user interface and graphical organ program selection. The positioning guide display on both the in-room touch user interface and the workstation supports precise, consistent patient positioning. Advanced motorization and tracking reduce the physical exertion of technologists and help prevent repetitive stress injuries.

The FDA cleared the system In January 2019.
