SimRT - 4D and Breath-Hold CT Contactless Motion Monitoring Platform
The SimRT system is a sophisticated contactless motion monitoring platform utilized in radiation therapy, offering heightened precision in 4D and breath-hold CT simulations. This system is engineered to ensure optimal image quality by mitigating patient movement, which is crucial for treatment planning involving tumors influenced by respiratory motion, such as those located in the breast, lungs, and liver. Traditional CT methods can be labor-intensive, causing variability and discomfort due to the use of physical markers or blocks. SimRT's innovative approach eliminates these challenges through the use of ceiling-mounted cameras and virtual tracking points, ensuring minimal patient distraction and enhanced workflow efficiency. Optional modules such as PatientSide provide in-room monitoring and feedback, further refining the simulated environment for accurate treatment delivery, while improving patient and therapist experiences.
Accurate treatment begins with accurate simulation. Any patient movement during simulation can compromise image quality, particularly for tumours affected by respiratory motion (e.g., breast, lung, liver), resulting in suboptimal treatment planning and reduced treatment effectiveness. Traditional CT workflows can be time-consuming, rely on physical blocks, and may introduce variability or discomfort for patients.
SimRT changes that.
Reduce Rescan Rates
Impact of SimRT on rescan rate – University Hospital Birmingham
“Using SimRT together with PatientSide and the Real Time Coach has reduced our DIBH rescan rate from 14.9% to 2.3%1. This has reduced the need for rescans with associated contouring and planning work.”
Enhanced Accuracy
A recent study showed SimRT was 3x more accurate than a physical surrogate method for predicting tumor movement with 4DCT. SimRT showed more precise, stable breathing tracking leading to a more realistic 4DCT reconstruction and breathing-adapted treatment planning.
Non-Invasive Patient Experience
The use of a ceiling-mounted camera to monitor and record the patient eliminates the need for physical markers, blocks or belts – this results in less physical distraction for the patient, no errors due to skin deformation and nothing to set-up or clean.
More Efficient Breath-Hold Coaching
Our Real Time Coach display provides simple and intuitive visual feedback for patients, and our PatientSide in-room interface allows staff to stay closer to the patient for longer – this results in an easier breath-hold coaching experience and greater patient compliance
Faster, Simplified Workflows
SimRT’s Virtual Tracking Point selection enables rapid optimization of the tracking point set-up from the Control Room, meaning minimal patient distraction pre-scan and a more efficient workflow. The Virtual Tracking Point also allows for fast, easy identification of belly-breathers, as it can be placed anywhere on the body, regardless of patient physiology.
