HeadAnd neck brachytherapy
Why brachytherapy for head and neck?
- Brachytherapy is an important and successful part of the multidisciplinary treatment of head and neck cancer
- Can be used as a stand alone treatment or in combination with external beam radiation therapy
- Valuable also for salvage treatments

Applicator selection
Diagnostic imaging guides the applicator choice
Head and neck applicators
Our wide array of applicators are available for many applications, the Nasopharyngeal applicator and different sizes of flexible catheters with corresponding buttons can be used for different head and neck body areas.
Applicator insertion
Rotterdam Nasopharyngeal Mold Applicator Optimal dose shaping in nasopharyngeal cavities The Rotterdam nasopharyngeal mold is manufactured from a flexible silicone material to easily shape the radiation dose in the nasopharyngeal cavity. It consists of two channels on the upper surface to optimize the dose distribution and reduce the surface dose. The mold can remain in place for a series of treatment fractions, while the treatment catheters will be replaced per fraction. This way, patient discomfort between fractions is minimized. Why the Rotterdam nasopharyngeal mold applicator?
- Easily conforms to a range of nasopharyngeal cavity sizes
- Dual-channel design for optimized dose distribution
- Quick catheter reinsertion for follow-up fractions

Imaging
Determine applicator position relative to tumor and OaR
Image data set for treatment planning is obtained through X-ray, CT or MR imaging. The image quality determines the applictor visibility for correct recontruction It also give the anatomy landscap which shows the tumor and the OaR
“I wanted an applicator that was easy to use, did not require a general anesthetic and that would closely conform to the mucosa of the nasopharynx. I found it in the Rotterdam nasopharyngeal applicator.”
Treatment planning
Homogeneous dose delivery on the target while sparing the OaR
Oncentra胸罩chy
Comprehensive treatment planning software
Designing the optimal dose distribution can be a time-consuming job. The latest version of Oncentra Brachy offers a series of useful tools that simplify many repetitive tasks, such as contouring and reconstruction. Oncentra Brachy buys you time to focus on what counts: creating the optimal dose distribution.
Oncentra短还能帮助你优化治疗plan accuracy, providing easy navigation to any plane that offers the most relevant information per region of interest. Template solutions for repetitive tasks, such as the new Implant Modeling tool and the popular Applicator Modeling feature, help reduce implant reconstruction time. DVH presets and the ROI Catalog Manager can help improve accuracy and reproducibility. Powerful inverse planning optimization automates volume-based planning, making the process fast and efficient.
Reduce implant reconstruction time
- Instant applicator reconstruction in relation to anatomy
- Contains the complete geometry of Elekta’s gynecological applicators
- Includes the measured source paths of ring applicators
- Accounts for dose attenuation resulting from shielding during planning and shields are fully visible
Dose distribution calculated by ACE
- Algorithm based on the TG-186 recommendations published by the AAPM workgroup in 2012
- Algorithm based on the TG-186 recommendations published by the AAPM workgroup in 2012
- Discriminates between tissue, air and bone
- Accounts for tissue heterogeneities, lack of backscatter from areas with no tissue, applicator attenuation and shielding
Implant modeling tool
- Reconstruct multicatheter implants immediately
- Drag & Drop 3D applicator geometry for accurate and fast reconstruction
- Extra Coordinate System (ECS) allows quick and easy navigation to the correct plane views
Automatic dose optimization
IPSA
- Paired with the Dwell Time Deviation Constraint (DTDC)
- Limits high variation in dwell times
HIPO
- 用停留时间梯度限制改善计划优化（DTGR）
- Control high and low peaks in dwell times
- 焦点优化需要针头锁定
Treatment delivery
Safe, simple, intuitive brachytherapy workflow
Five simple features are the basis for the Flexitron way of working, introducing a new standard in treatment delivery
- Standardized transfer lengths, less prone to human errors during reconstruction as there is only one indexer length.
- Reference zero at entrance of applicator, no need to measure the distal tip.
- Metric dwell position numbering, 1 mm step size in a treatment window of 400 mm.
- 向前踏步导致在0,5mm精度范围内的可重复源定位
- Intuitive user interface, smooth navigation saves time.
Why Flexitron?
- Simple quality assurance
- 大型植入物的40个通道选项
- Connected to major oncology systems such as MOSAIQ®
- Safe investment with future upgrade potential
- Available in either Iridium-192 or Cobalt-60*
* Not available in all countries.
