Patient treatment set-ups require greater accuracy when compared to conventional treatments, including SBRT and IMRT. The devices utilized during patient simulation and set-up must be entirely homogenous while not interfering with the treatment beam. Sharp edges, varying densities, and bulky devices are detrimental to effective proton beam delivery. The devices must be strong and secure, yet have zero effect on the proton beam. ZDi Solutions’ devices provide this accuracy and applicability.
It is imperative to utilize appropriate set-up devices to achieve strong, accurate treatment requirements while limiting any interference with the proton beam. Providing the ability to customize your patients’ treatment set-up devices is ZDi Solutions’ specialty.
A beam that partially passes through a device will alter that part of the beam. This can cause a decrease in the range (depth) of that part of the beam, changing the overall dose profile, leading to under-dosage of the tumor volume and increased dose to healthy tissues. Additionally, sub- optimal positioning increases the need for multiple beam angles, thus taking longer amounts of time to deliver the patient treatments. More treatment time compounds the chances for patient movement. ZDi Solutions’ devices are designed to decrease the likelihood of these occurrences.
ZDi Solutions is the first company in the world to explicitly specialize in Proton specific patient positioning devices. Other companies have attempted to create proton-friendly set-up devices, but they seem to lack the full understanding of the simulation and treatment process. ZDi Solutions was founded and developed by a proton therapist who created the designs intentionally for the proton therapy clinical setting.
Depending on protocol, it is realistic to successfully treat a patient in 15-20 minutes a day when utilizing ZDi Solutions’ devices. Approximately 8-12 minutes is spent daily to align each patient to his or her marks, perform IGRT to align the anatomy, and save the set-up for treatments. On average, 2 minutes per field is required to deliver each dose. Overall, this time savings could prove to be significant for both patients and healthcare providers.
There are some intensely basic differences between Proton Therapy and conventional Radiation Therapy, including fundamental treatment concepts, patient positioning, and machine dynamics. With comprehensive training and educational modalities at hand, ZDi Solutions offers solutions to help master your clinical and didactic challenges.
It was noted by MacDonald, et al. (2013) in their study entitled "Proton Therapy for Breast Cancer After Mastectomy: Early Outcomes of a Prospective Clinical Trial," that proton treatments were well tolerated. The authors reported that, "skin reactions were mostly superficial and often with moderate to severe erythema and moderate to large areas of dry superficial desquamation."
