10/24/23 - First Annual Colorado Springs Witches, Warlocks, & Ghouls Bicycle Ride a huge success! 

The First Annual Colorado Springs Witches, Warlocks, & Ghouls Bicycle Ride on Saturday was a huge success, raising over $10,000 to support the Memorial Hospital Circle of Hope, a fund that helps patients in need cover uncovered expenses such as daily transportation during their treatment course. Lead organizers Tecie Haller and Mackenzie Daly (third and fourth from left) are shown here alongside other faculty, family, and a furry friend. The event was a bike ride in costume along a beautiful parkway in Colorado Springs, and the weather was superb!

10/17/23 - Computer vision surface imaging breast DIBH project granted funding by Cancer Center

“In an ongoing cross-institutional collaboration with the Department of Computer Science at CU Boulder and the Department of Bioengineering at CU Anschutz, we are using artificial intelligence (AI) and computer vision to improve real time patient alignment and tracking for breast cancer patients.  This project, “Computer vision enhanced breast DIBH-RT “, will allow improved protection of the heart and lungs, lowering the risk of cardiac and lung toxicity and reducing the risk of heart disease and lung cancer.”

7/28/23 - Patient Access and Patient Experience Scores in top 90th percentile


Celeste Trevino, Manager of Clinic Nursing, shared good news with the staff about the annual performance metrics for the Radiation Oncology Department at AMC. The patient experience results for  April 2022-March 2023 have resulted and we are in the outstanding range (90th + percentile) with our  patient access and patient experience scores. In fact, we had both the highest patient experience score  and the highest patient access score of any department in the hospital! Our department could not have  achieved these metrics without the each of the team members that make our department. From check in  to check out, and through all the background work that is unseen, the patients that walk through our  department encounter many different groups of people who make their treatment experience as seamless  as possible. The positive experience we provide to our patients would not be possible without each  Radiation Therapist, Nurse, Dosimetrist, Physicist, Provider, PAS team member, Administrative Staff  Member, and Manager on this team. Thank you to all of you for your steadfast dedication to our patients;  your efforts have been recognized and you should all be very proud!
