"I opened up my own CT simulation, as I wanted to see where AutoContour would place nodal volumes compared to where our physicians had drawn them. Supraclavicular, Axillary, and IMNs all overlayed beautifully."

We are thrilled to introduce our exceptional October User of the Month, a true symbol of resilience and inspiration. Meet Marjorie Seidel, a seasoned dosimetrist with over 30 years of experience, whose journey through personal health battles has only strengthened her commitment to delivering top-notch patient care. Marjorie bravely shares her courageous health journey, having faced both Ewings Sarcoma and a recent diagnosis of Breast Cancer. She has undergone intensive treatments resulting in neuropathy and lymphadenopathy that has ultimately affected her contouring dexterity. “AutoContour came at the perfect time. I feel that I am now able to continue working in a complex, fast-paced environment while maintaining accurate contouring requiring minimal editing.”


The first case that Marjorie opened in AutoContour was her own CT Simulation. “I wanted to see where the software would place nodal volumes compared to where our physicians had drawn them.  Supraclavicular, Axillary, and IMNs overlayed beautifully. Also, brachial plexus, parotid, cochlea, and optic structures all showed the same great results.”

Reflecting on her experiences, Marjorie acknowledges the initial struggle of transitioning from a dedicated dosimetrist to a patient. She learned to trust her team, knowing that she would receive the same excellent care she and her colleagues provide to patients every day.


If she didn’t already have enough on her plate, Marjorie also started the US-based Halcyon Planning Group (Facebook / LinkedIn), and encourages all Halcyon users to join. She highlights the unique challenges posed by the Halcyon’s stacked MLCs and 6FFF beam, and acknowledges Radformation software for enabling quick 3D comparison plans with EZFluence and clear simple plan comparisons with ClearCheck.

Beyond her work in the clinic, Marjorie has a vibrant array of hobbies, including extensive travel, pug rescue, advocacy for cancer care, reading, crafts, and enjoying the great outdoors. Her diverse interests mirror her dynamic and positive approach to life, and help her balance the demands of an important profession while overcoming real-life challenges.

Marjorie's journey is a shining example of excellence, resilience, and a passion for providing top-quality patient care. Her positivity is an inspiration to us all, embodying the values of strength, dedication, and compassion.
