Aktina Medical Showcases Solutions to Ensure Radiation Treatment Accuracy at ASTRO 2017

 

Aktina Medical, a leader in designing and manufacturing quality radiation oncology systems, is showcasing new solutions designed to ensure the accuracy of radiation therapy treatments at ASTRO’s 2017 Annual Meeting. Products showcased include the company’s Respiratory Compression Belt, SRS Cone Adapters and immobilization systems for Stereotactic Body Radiation Therapy (SBRT).

 

“We have a very pragmatic philosophy when designing new products – to solve longstanding issues that plague physicists, treatment providers and patients in the most efficient and cost-effective manner possible,” said Nicholas G. Zacharopoulos, COO, Aktina Medical. “At ASTRO, we have the opportunity to display our latest products while engaging medical experts to accumulate information that will benefit the industry at large moving forward.”

 

Featured Aktina Medial products on display at ASTRO include:

 

The newly enhanced Respiratory Compression Belt which ensures greater treatment accuracy and patient comfort by comfortably restricting movement resulting from the patient’s respiratory cycle. Ideal for abdominal and lung treatments, the Respiratory Compression Belt applies 360-degree pressure evenly around the entire periphery of the patient; allows for the application of user defined pressure; and is adjustable to allow for different size patients. Unique to Aktina Medical’s Respiratory Compression Belt is a patented remote access kit, which allows therapists to monitor and adjust the belt pressure from outside the treatment vault as well as from inside. This helps patient throughput move smoothly, increasing overall efficiency at busy clinics.

 

Interlocking SRS Cones with automated treatment verification solves the long-existing radiation therapy problem of incorrect cone size selection at time of treatment. The patented system was the first of its kind to provide LINAC interlocks for incorrect cone size by encoding the aperture size mechanically to the cone. The interchangeable cones are lightweight and extremely accurate, available from 5mm through 40mm field sizes in increments of 1mm and can be integrated with Elekta’s LINAC Radiotherapy system for use within the Philips Pinnacle3 , Elekta Monaco, and RaySearch RayStationTreatment Planning Systems. Also showcased at ASTRO is an improved SRS cone adapter with a new two-stage precision adjustment mechanism for simpler and more accurate cone adjustments.

 

Products and accessories for SRS and SBRT include Aktina’s Pin-Point Vacuum Fixation Systems for sub-millimeter intracranial treatments with a variety of head support options, consumables and replacement parts.

Aktina Medical’s New Respiratory Compression Belt Helps Improve Radiation Therapy Accuracy

 

As new radiation therapy techniques and treatment procedures are developed and implemented, medical professionals are turning to new assistive positioning devices to help ensure precise targeting of a tumor’s location. A leader in patient positioning and immobilization solutions for radiation therapy, Aktina Medical has introduced a newly enhanced Respiratory Compression Belt designed to help ensure greater accuracy and patient comfort.

 

“Since its introduction in 2009, our Respiratory Compression Belt has been well integrated into the clinical process at oncology facilities across the country,” said Nicholas G. Zacharopulos, COO, Aktina Medical. “With enhancements such as a remote access kit allowing pressure to be monitored and adjusted from the treatment console area, our latest Compression Belt becomes an even more valuable tool for cancer treatment.”

 

Pressure can be applied to Aktina Medical’s Respiratory Belt to restrict movement resulting from the patient’s respiratory cycle. Ideal for abdominal and lung treatments, the Respiratory Belt applies 360-degree pressure evenly around the entire periphery of the patient; allows for the application of user defined pressure; and is adjustable to allow for different size patients.

 

Unique to Aktina Medical’s Respiratory Belt is a patented remote access kit, which allows therapists to monitor and adjust belt pressure from outside the treatment vault as well as from inside. This helps patient throughput move smoothly, increasing overall efficiency at busy clinics – while also being a cost effective way to provide abdominal compression.

Aktina Medical Announces Collaboration with Philips Medical Systems and Elekta Instruments for SRS Interlocking

Safety Interlocks Ensure Correct Cone Size at Time of Treatment

 

Aktina Medical is proud to announce a collaboration with Philips Medical Systems and Elekta Instruments for SRS interlocking at the 2017 American Association of Physicists in Medicine (AAPM) conference. Aktina’s SRS Cone Adapter and Elekta’s LINAC Radiotherapy system are now integrated and automated for use within the Philips Pinnacle3 Treatment Planning System.

 

“Pinnacle TPS will now be capable of connecting directly to Elekta’s LINAC system with the full integration of Aktina’s Interlocked SRS cones. This functionality means that all safety interlocks will be automatically transferred along with the treatment plan in DICOM format,” said Nicholas G. Zacharopoulos, COO, Aktina Medical. “No manual intervention will be required to ensure that the correct cones size and jaw sizes are implemented at the time of treatment.”

 

“With the first truly interlocked cones, Aktina really set a new benchmark for safety in SRS treatments,” said Shrikant S. Kubsad, Ph.D., DABR. Director, Medical Physics, Bismarck Cancer Center. “And now that the cone interlock is fully integrated and automated within the Pinnacle planning system, the radiation oncology community will start to receive the full benefits of this partnership.”

 

Aktina’s adapter simply snaps onto the Elekta LINAC head without any need for collimator faceplate modifications. Aktina’s interchangeable cones are lightweight and extremely accurate, available from 5mm through 40mm field sizes in increments of 1mm. Each cone is uniquely recognized by the Elekta LINAC through the system’s bar code scanner, and the cones are electronically interlocked through the Elekta Record and verify system by a series of micro switches embedded in the cone applicator. Together, these elements help automate the confirmation process and help reduce potential errors that could occur at treatment.

 

“It is a pleasure working with Aktina, as they are very open and eager to implement this very important interlocking integration,” said Catherine Large, Physics Support Specialist, Philips Medical Systems. “Our Pinnacle SRS module is much more user friendly and safer with this collaboration.”

 

Philips is scheduled to release the Aktina Cones interlocked functionality in Q1 2018.

International Cancer Center Reports PinPoint Results

lovo image1
The International Cancer Center (Centro Internacional de Cancer) of the Hospital de Diagnostico, is the first dedicated comprehensive cancer center in El Salvador, it was established in February of 2011, promoting cancer awareness, early detection and advanced cancer treatments. It was the second institution in Latin-America to incorporate Tomotheraphy and the first institution to establish an Image Guided Body Radiosurgery Program (IGBRS).

Dr. Eduardo Lovo is a Neurosurgeon whose main interest are in Neurological Oncology and Radiosurgery, he has introduced multiple innovative techniques to El Salvador and Central America such as: Tractography Image Guided Surgery (IGS), awake craniotomy and cortical mapping for tumors in eloquent cortex, intraoperative ultrasound and most recently, Cranial and Spinal Radiosurgery with Tomotheraphy. He is the current Medical Director of The International Cancer Center of The Hospital de Diagnostico de El Salvador and Coordinator of the Neuro-oncology program of the same Hospital.

The Aktina PinPoint system was incorporated in early march of 2011 as a tool that could potentially immobilize patients to true intracranial radiosurgical standards, exploding the image guidance system capacity of Tomotheraphy (on-board CT), as well as highly conformal radiation distribution. In our hypothesis this combination could bring new and improved characteristics to the more traditional stereotactic radiosurgery schemes, such as: shorter treatment times (<30 minutes), maximum patient comfort (truly painless), elimination of potential “target miss” as this set-up is not dependent on stereotactic coordinates (eliminating erroneous determination or manual execution of coordinates) or unperceived frame slippage that without a 3D Image Guidance (CT) immediately before treatment would not had been detected, and finally it could facilitate fractionated radiosurgical (?5 fractions) treatments that are beneficial for larger lesions and organs at risk (AOR) sparing.
Since then, in a short period of time more than 40 radiosurgical sessions have been given for intracranial pathology. Our current investigative work was designed to determine patient movement during radiosurgical treatments with Aktina Pin-Point system; it basically consisted in doing the obligatory Megavoltage-CT (MVCT) before treatment and a second MVCT at the end of treatment, as well as a final image fusion to determine the amount of movement that had occurred.

Ten patients were included that harbored 12 intracranial tumors and that were treated with 18 radiosurgical sessions, six patients received single fraction radiosurgery and four received fractionated radiosurgery. Our results demonstrated that corrected movement for negative and positive values for X 0.47 mm, Y 0.56 mm, Z 0.37 mm and Roll axis was of 0.36 mm. http://www.aktina.com/news/international-cancer-center-reports-pinpoint-results/Average beam on time was 12.2 minutes, if patient setup and both MVCTs (before and after) were taken into consideration average time of treatment was 31.2 minutes (22.1-42 minutes).

The main advantages we have seen with this treatment set-up are true radiosurgical head immobilization standards in comparison to face-mask where patient movement can be above 1mm.

“The PinPoint system is quite simple to use with a small learning curve, paying attention to details (head mold, no air leaks in the teeth mold, etc) is the “key” for adequate intracranial radiosurgery, paying attention to details is no different than conventional stereotactic radiosurgical procedures, with the main difference that it is non-invasive in nature.”
