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.

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.

Cynthia McCollough, Ph.D., director of the Mayo Clinic Computed Tomography (CT) Clinical Innovation Center, professor of medical physics and biomedical engineering, and the 2019 president of the American Association of Physicists in Medicine (AAPM), explains the "building bridges" theme of the 2019 AAPM meeting. 

This theme was the focus of her president’s address at the 2019 AAPM meeting. She spoke on the theme of diversity and how to break down the barriers between various minorities, male-female, religion, national origin, etc. She gave many photo examples of how we pigeon hole people into neat categories and that we often say we have equally in society, however her images showed recent images of big political summits where there are no women present, or they were the secretaries in the background. She said in medical practice, department administration and collaboration on projects, people need to be cognoscente of bias they have engrained by culture for which they may not even be aware.

She showed a slide of the AAPM membership makeup by generation and said members need to keep in mind the way each generation thinks and communicates varies by their generation's life experience and upbringing. McCollough said understanding these differences can help bridge perceived gaps in communication.

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.

Nina Kottler, M.D., vice president of clinical operations, Radiology Partners, explains how the company developed its own artificial intelligence (AI) application to check the accuracy of radiologists' reports as they dictated and to follow-up automatically on incidental findings. She spoke at the 2019 Radiology AIMed conference.

She said the AI sits on top of Radiology Partners' natural language processing application and will immediately flag any comments that do not appear to make sense or might need clarification. Instead of forcing radiologists to change their workflow to create structured reports, Kottler said this AI software helps adapt the existing workflow to make the reports more consistent and able to be data mined later.

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. 

At ASTRO 2018, Accuray showcased new patient-first innovations, including motion synchronization on Radixact, and the new CK VoLO, a fast optimizer on the CyberKnife system. Andrew Delao, senior director of marketing for Accuray, highlights the new features.
