Elekta Xoft Axxent 110 Controller 

IORT Brachytherapy System

LIKE-NEW CONDITION

The Elekta Xoft Axxent 110 Controller is a robust system designed for Intraoperative Radiation Therapy (IORT), used in the field of oncology--designed for delivering high dose rate (HDR), low-energy radiation for intraoperative radiation therapy (IORT) and other brachytherapy applications.. The controller is integral for delivering precise radiation doses during surgical procedures, enhancing treatment efficacy while minimizing exposure to surrounding healthy tissues. This equipment is engineered with user convenience in mind and ensures seamless integration into existing treatment setups. Manufactured by Elekta Xoft, previously known as i

iCAD, this system stands as a testament to durability and precision in medical technology. It supports clinicians by providing the necessary controls and parameters to optimize therapeutic interventions for cancer patients. As a part of the cutting-edge Axxent series, this controller upholds high standards of safety and performance. This makes the Xoft Axxent 110 Controller a practical choice for healthcare facilities looking to bolster their radiotherapy capabilities with a trusted piece of equipment.

Functionality:

The Axxent 110 Controller is part of the Xoft Axxent eBx System, which uses a miniaturized X-ray source to deliver isotope-free, HDR, low-energy radiation (50 kV) directly to the tumor site.

Enables precise, targeted radiation therapy in a minimally shielded environment, sparing surrounding healthy tissue.

Specifically designed for flexibility in various treatment settings, including intraoperative radiation therapy (IORT) for cancers such as early-stage breast cancer, non-melanoma skin cancer (NMSC), and gynecological cancers. Emerging applications include prostate, pancreatic, and colorectal cancers.

Radiation Source:

Utilizes a proprietary, miniaturized X-ray tube operating at 50 kV with a beam current of approximately 300 μA, producing bremsstrahlung X-rays with a mean energy of 26.7 keV. Radiation is emitted only when the X-ray source is powered on, unlike isotope-based systems, enhancing safety and reducing shielding requirements.

Features extended source life cooling with non-toxic, clear circulating cooling fluid to maintain proper tube temperature during operation.

Mobility and Portability:

Weighs approximately 200 pounds with a small footprint, making it highly mobile and suitable for a wide range of clinical settings, including standard operating rooms with minimal shielding requirements due to fast dose fall-off. Designed for easy transport, increasing access to electronic brachytherapy treatment options.

User Interface:

Equipped with a touch screen panel providing step-by-step instructions and real-time treatment information for ease of use. Integrates with the Axxent Hub, a cloud-based repository for documentation, quality assurance, and treatment management, enhancing workflow efficiency.

Applicators and Accessories:

Compatible with a range of applicators tailored for specific treatments:

Balloon Applicators:

Flexible silicone balloons in multiple sizes for intracavitary and IORT delivery, ensuring precise fit and conformal radiation dose. Features include separate ports for drainage, saline fill, and X-ray source insertion, with radiopaque walls for improved visibility on CT or planar imaging.

Vaginal Applicators:

Four-channel applicators for targeted brachytherapy in the vagina and rectum.

Cervical Applicators:

Three-channel applicators with titanium walls to filter low-energy radiation, designed for cancers of the uterus, cervix, endometrium, and vagina.

Surface Applicators:

Sizes ranging from 10 mm to 50 mm for NMSC treatment, enabling precise delivery with minimal dose to healthy tissue.

FlexiShield:

A flexible, non-sterile, lead-equivalent material to reduce scatter radiation, allowing clinical staff to remain in the room during treatment.

Rigid Shield:

Optional for additional protection of tissues or organs during IORT or other procedures.

Physics Accessories Kit:

Includes gauges and catheters (e.g., X-ray source length gauge, applicator depth gauge, CT/fluoro-compatible marker catheters) for quality assurance to confirm system parameters and proper operation.

Dosimetric Characteristics:

Percent Depth Dose (PDD): Approximately 7-7.5% drop-off per mm, comparable to other electronic brachytherapy systems like Esteya.

Dose Rate:

For a 35 mm applicator, the dose rate is approximately 1.3 Gy/min.

Beam Flatness and Symmetry: Within 5% over the central 80% of the field width for applicators (10 mm, 20 mm, 35 mm, 50 mm).

Beam Stability:

Voltage variations are within manufacturer specifications (50 ± 1 kV). Half Value Layer (HVL) and penumbra characteristics are optimized for precise targeting.

Shielding and Safety:

Minimal shielding requirements due to low-energy radiation and fast dose fall-off, enabling treatment in standard rooms or operating suites.The FlexiShield and Rigid Shield reduce scatter radiation, enhancing safety for both patients and clinical staff.

The system’s isotope-free design eliminates the need for handling radioactive materials, reducing regulatory and safety concerns.

Clinical Applications:

IORT for Breast Cancer: Delivers a single fraction or boost dose during surgery, reducing the need for multiple external beam radiation sessions. FDA-cleared for postoperative breast cancer treatment.

Non-Melanoma Skin Cancer (NMSC): The Axxent SPX Controller, optimized for surface treatments, supports scar-free, non-invasive treatment with applicator sizes from 10 mm to 50 mm.

Gynecological Cancers: Targeted therapy for endometrial and cervical cancers using vaginal and cervical applicators.

Emerging Indications: Under investigation for prostate, pancreatic, colorectal, and brain cancers.

Regulatory:

FDA-cleared for intracavitary or interstitial radiation following lumpectomy for breast cancer and for surface brachytherapy, including IORT, for various indications.

Manufactured by Xoft Inc., with Elekta as the exclusive distributor for brachytherapy products. Not available in all markets.

Workflow Efficiency:

Accelerated treatment times enhance operational efficiency and patient satisfaction.

The system’s design supports streamlined installation, training, and treatment processes.

Barcode scanning (on the SPX Controller) facilitates HIPAA compliance and improves workflow efficiency.
