The Remove-the-Mask Open-Source head and neck Surface-Guided radiation therapy system.

ABSTRACT:

Background and purpose

Surface Guided Radiotherapy (SGRT) for head and neck radiotherapy is challenging as obstructions are common and non-rigid facial motion can compromise surface accuracy. The purpose of this work was to develop and benchmark the Remove the Mask (RtM) SGRT system, an open-source system especially designed to address the challenges faced in radiotherapy of head and neck cancer.

Materials and methods

The accuracy of the RtM SGRT system was benchmarked using a head phantom positioned on a robotic motion platform capable of sub-millimetre accuracy which was used to induce unidirectional shifts and to reproduce three real head motion traces. We also assessed the accuracy of the system in ten humans volunteers. The ground truth motion of the volunteers was obtained using a commercial motion capture system with an accuracy < 0.3 mm.

Results

The mean tracking error of the RtM SGRT system for the ten volunteers was of -0.1 ± 0.4 mm -0.6 ± 0.6 mm and 0.3 ± 0.2 mm, and 0.0 ± 0.2^° 0.0 ± 0.1^° and 0.0 ± 0.2^° for translations and rotations along the left-right, superior-inferior and anterior-posterior axes respectively and we also found similar results in measurements with the head phantom. Forced facial motion was associated with lower tracking accuracy. The RtM SGRT system achieved submillimetre accuracy.

Conclusion

The RtM SGRT system is a low-cost, easy to build and open-source SGRT system that can achieve an accuracy that meets international commissioning guidelines. Its open-source and modular design allows for the development and easy translation of novel surface tracking techniques.

Project description:Radiomics leverages existing image datasets to provide non-visible data extraction via image post-processing, with the aim of identifying prognostic, and predictive imaging features at a sub-region of interest level. However, the application of radiomics is hampered by several challenges such as lack of image acquisition/analysis method standardization, impeding generalizability. As of yet, radiomics remains intriguing, but not clinically validated. We aimed to test the feasibility of a non-custom-constructed platform for disseminating existing large, standardized databases across institutions for promoting radiomics studies. Hence, University of Texas MD Anderson Cancer Center organized two public radiomics challenges in head and neck radiation oncology domain. This was done in conjunction with MICCAI 2016 satellite symposium using Kaggle-in-Class, a machine-learning and predictive analytics platform. We drew on clinical data matched to radiomics data derived from diagnostic contrast-enhanced computed tomography (CECT) images in a dataset of 315 patients with oropharyngeal cancer. Contestants were tasked to develop models for (i) classifying patients according to their human papillomavirus status, or (ii) predicting local tumor recurrence, following radiotherapy. Data were split into training, and test sets. Seventeen teams from various professional domains participated in one or both of the challenges. This review paper was based on the contestants' feedback; provided by 8 contestants only (47%). Six contestants (75%) incorporated extracted radiomics features into their predictive model building, either alone (n = 5; 62.5%), as was the case with the winner of the "HPV" challenge, or in conjunction with matched clinical attributes (n = 2; 25%). Only 23% of contestants, notably, including the winner of the "local recurrence" challenge, built their model relying solely on clinical data. In addition to the value of the integration of machine learning into clinical decision-making, our experience sheds light on challenges in sharing and directing existing datasets toward clinical applications of radiomics, including hyper-dimensionality of the clinical/imaging data attributes. Our experience may help guide researchers to create a framework for sharing and reuse of already published data that we believe will ultimately accelerate the pace of clinical applications of radiomics; both in challenge or clinical settings.

Project description:PurposeTo identify which patient-reported outcomes (PROs) may be most improved through adaptive radiation therapy (ART) with the goal of reducing toxicity incidence among head and neck cancer patients.MethodsOne hundred fifty-five head and neck cancer patients receiving radical VMAT (chemo)radiotherapy (66-70 Gy in 30-35 fractions) completed the MD Anderson Symptom Inventory, MD Anderson Dysphagia Inventory (MDADI), and Xerostomia Questionnaire while attending routine follow-up clinics between June-October 2019. Hierarchical clustering characterized symptom endorsement. Conventional statistical approaches indicated associations between dose and commonly reported symptoms. These associations, and the potential benefit of interfractional dose corrections, were further explored via logistic regression.ResultsRadiotherapy-related symptoms were commonly reported (dry mouth, difficulty swallowing/chewing). Clustering identified three patient subgroups reporting: none/mild symptoms for most items (60.6% of patients); moderate/severe symptoms affecting some aspects of general well-being (32.9%); and moderate/severe symptom reporting for most items (6.5%). Clusters of PRO items broadly consisted of acute toxicities, general well-being, and head and neck-specific symptoms (xerostomia, dysphagia). Dose-PRO relationships were strongest between delivered pharyngeal constrictor Dmean and patient-reported dysphagia, with MDADI composite scores (mean ± SD) of 25.7 ± 18.9 for patients with Dmean <50 Gy vs. 32.4 ± 17.1 with Dmean ≥50 Gy. Based on logistic regression models, during-treatment dose corrections back to planned values may confer ≥5% decrease in the absolute risk of self-reported physical dysphagia symptoms ≥1 year post-treatment in 1.2% of patients, with a ≥5% decrease in relative risk in 23.3% of patients.ConclusionsPatient-reported dysphagia symptoms are strongly associated with delivered dose to the pharyngeal constrictor. Dysphagia-focused ART may provide the greatest toxicity benefit to head and neck cancer patients, and represent a potential new direction for ART, given that the existing ART literature has focused almost exclusively on xerostomia reduction.

Project description:BACKGROUND:MR-guided focused ultrasound or high-intensity focused ultrasound (MRgFUS/MRgHIFU) is a non-invasive therapeutic modality with many potential applications in areas such as cancer therapy, drug delivery, and blood-brain barrier opening. However, the large financial costs involved in developing preclinical MRgFUS systems represent a barrier to research groups interested in developing new techniques and applications. We aim to mitigate these challenges by detailing a validated, open-source preclinical MRgFUS system capable of delivering thermal and mechanical FUS in a quantifiable and repeatable manner under real-time MRI guidance. METHODS:A hardware and software package was developed that includes closed-loop feedback controlled thermometry code and CAD drawings for a therapy table designed for a preclinical MRI scanner. For thermal treatments, the modular software uses a proportional integral derivative controller to maintain a precise focal temperature rise in the target given input from MR phase images obtained concurrently. The software computes the required voltage output and transmits it to a FUS transducer that is embedded in the delivery table within the magnet bore. The delivery table holds the FUS transducer, a small animal and its monitoring equipment, and a transmit/receive RF coil. The transducer is coupled to the animal via a water bath and is translatable in two dimensions from outside the magnet. The transducer is driven by a waveform generator and amplifier controlled by real-time software in Matlab. MR acoustic radiation force imaging is also implemented to confirm the position of the focus for mechanical and thermal treatments. RESULTS:The system was validated in tissue-mimicking phantoms and in vivo during murine tumor hyperthermia treatments. Sonications were successfully controlled over a range of temperatures and thermal doses for up to 20 min with minimal temperature overshoot. MR thermometry was validated with an optical temperature probe, and focus visualization was achieved with acoustic radiation force imaging. CONCLUSIONS:We developed an MRgFUS platform for small-animal treatments that robustly delivers accurate, precise, and controllable sonications over extended time periods. This system is an open source and could increase the availability of low-cost small-animal systems to interdisciplinary researchers seeking to develop new MRgFUS applications and technology.

Project description:ObjectiveThe primary aim of this investigation is to assess the effectiveness of implementing an innovative immobilization approach, spec ically the utilization of personalized open-face masks in combination with styrofoam fixation, for head and neck cancers receiving radiotherapy. The study seeks to evaluate the influence of this method on improving patients' precision in positioning and their overall comfort during the treatment process, in addition to exploring its potential capacity to mitigate the occurrence of anxiety and depression in this patient population.MethodsA prospective, randomized controlled trial was undertaken to investigate the comparative efficacy of two immobilization approaches for the radiotherapy treatment of head and neck cancers. The experimental group was randomly assigned to receive fixation using personalized open-face masks with nose and mouth apertures, while the control group was immobilized using closed-face masks. Weekly cone-beam computed tomography (CBCT) scans were conducted pre-treatment to assess and record setup errors along three axes. Comparative analysis of setup errors and the planning target volume (PTV) margin between the two groups was performed. Furthermore, the patients' comfort levels and anxiety and depression status were evaluated using the modified Likert questionnaire and the Hospital Anxiety and Depression Scale (HADS).ResultsA total of 106 patients were enrolled in the study and randomly assigned to either the experimental group (n = 53) or the control group (n = 53). There were no statistically significant differences observed between the two groups in terms of age, sex, and disease type indicating comparability. Analysis of the setup errors along different directions showed no significant differences between the experimental and control groups in the X direction (0.90 ± 0.84 mm vs. 0.92 ± 0.85 mm, p = 0.825), Y direction (1.26 ± 0.98 mm vs. 1.37 ± 1.09 mm, p = 0.172), Z direction (1.18 ± 0.84 mm vs. 1.15 ± 0.98 mm, p = 0.651), and Rtn direction (0.65 ± 0.57 vs. 0.62 ± 0.55, p = 0.489). Evaluating the local setup errors in the experimental and control groups, there were no significant differences observed in the X direction (1.13 ± 1.15 mm vs. 1.01 ± 0.89 mm, p = 0.152) and Z direction (1.31 ± 0.88 mm vs. 1.26 ± 1.17 mm, p = 0.549). However, a significant difference was found in the Y direction (1.49 ± 1.19 mm vs. 1.80 ± 1.45 mm, p = 0.003). The Rtn direction also did not show a significant difference (0.90 ± 0.81 vs. 0.84 ± 0.73, p = 0.328). The PTV margin in the X, Y, and Z directions were determined as 2.20 mm, 3.12 mm, and 2.57 mm in the experimental group and 2.35 mm, 3.58 mm, and 2.86 mm in the control group, respectively. The personalized open-face mask patients reported higher levels of comfort compared to the perforated head, neck, and shoulder thermoplastic mask (31.32 ± 1.16 vs. 30.00 ± 1.49, p < 0.001). The prevalence rates of anxiety in the experimental and control groups were as follows: (18.8% vs. 12.5%, p = 0.399), (18.8% vs. 14.6%, p = 0.584), (23.4% vs. 25%, p = 0.856), and (23.4% vs. 33.3%, p = 0.283).ConclusionsIn head and neck cancer radiotherapy, we propose the idea of personalized open-face mask combined with styrofoam for the first time, which can improve patient comfort without sacrificing positioning accuracy, and has a tendency to relieve patients' tension and anxiety. It is worth promoting and using in clinical positioning.
