The ExaFix positioning systems provide accurate positioning and fixation of the patient during radiotherapy treatment in the head- and neck region. The ExaFix patient positioning platform is based on an accepted template.Both carbon fiber and acrylic designs are produced with high accuracy and with respect to dosimetry, freedom of treatment and comfort.
The head- and neck systems are developed and produced with state of the art special 3-D molding- and production techniques which allow user-friendly shapes with focus on the significant and important regions with respect for low tolerances in attenuation and dosimetry.
All head- and neck systems are 2-pin-ready and compatible with various styles of indexing systems and couchtops. The ExaFix baseplates are prepared for 3- and 5 fixation point mask-types. The aperture in the baseplate offers the option to use different styles of head supports.
Complementary options like the ExaTilt carbon fiber inclination plate are available.

The use of low temperature thermoplastics is an accepted and appreciated concept for immobilizingpatients during radiotherapy treatment. Through joint cooperation, MacroMedics and a leadingthermoplastics manufacturer have designed a new line of thermoplastics offering high rigidity and very lowshrinkage with near transparency while processing the material.
MacroCast is a new developed low-temperature thermoplastic for radiotherapy applications providingexcellent reproducibility during treatment. MacroCast is available in different perforations, shapes andqualities.
The MacroCast non perfo is offering 'clear-control' characteristics during molding, allowing controlled surfacecontact in critical regions. The semi-transparency of the non perforated material allows for optimal contact between material and anatomical reference points and will result in a precise fitting and ultra rigid individual mask.

The stainless steel MacroBath water baths type 1 and 2 have been specifically designed for use with MacroCast thermoplastic materials. The MacroBath water bath is electronically controlled and digital adjustable to ensure the desired temperature for optimal moulding characteristics of MacroCast materials.

ACCESSOIRES

MacroBath TrolleyThis height adjustable trolley brings the MacroBath to a convenient work position.

EasyGripThe EasyGrip assists in an easy and efficient way the handling of the 5-points MacroCast. The tool allows an independent creation of a perfect MacroCast 5-point individual head- & neck immobilization.

Electron Block Foam CutterThe Electron Foam Cutter is a cutter which features an easy-to-change NiChrome wire assembly and a large cutting surface, making this an ideal unit for cutting electron foam.

Diagnostic scanners like CT, PET-CT and MRI have proven their essential value in radiotherapy. In all steps the patient is undergoing during the treatment process, uniformity and reproducibility in patient set-up is fundamental. To overcome the problems caused by the difference in geometry between concave scanner couchtops and flat simulator and linear accelerator couchtops MacroMedics offers light weight removable couchtops for various types of scanners.

All MacroMedics couchtops simply lock onto the cradle of the scanner with a clamping mechanism. This clamping mechanism allows the couchtop to be easily removed at any time. As all carbon fiber MacroMedics products, the diagnostic couchtops are developed and produced with state of the art 3-D molding- and production techniques with respect for low tolerances in attenuation and dosimetry. A low density foam core covered with thin layers of carbon fiber is the base construction for a very light weight and rigid product.

MacroMedics also offer the option to embed reference structures like phantom rods and copper positioning wires in the couchtop core.

MacroMedics easy-to-use vacuum cushions are manufactured of first class, high quality, durable and easy to clean materials. The vacuum cushion is a well known and widely accepted aid for patient immobilisation in radiotherapy.

MacroMedics vacuum cushions are filled with small polystyrene pellets to create a firm but comfortable cradle to accurately support and position the patient. They naturally adapt to the patients anatomical contours. A wide range of dimensions and filling volumes are available.

The vacuum cushions feature:

• Easy-to-use, reusable vacuum cushions
• Filled with small polystyrene pellets to create a firm but comfortable cradle around the patient
• The vacuum cushions are radiotranslucent and easy to clean
• Durable, high quality blue Polyamide cushions
• Most common types quick-release valves are available

MacroMedics introduces the Single Shell Positioning System (SSPS), a brand-new system offering increased stability for head, neck and shoulder positioning. Based on an accurate mechanical principle, the SSPS distinguishes itself from existing head, neck and shoulder systems and presents a completely new approach for increased set-up stability.A shortcoming of all current thermoplastic mask systems is that the mask material often becomes overstretched. This results in thin material and thus less stable patient set-up. The solution: the new Single Shell Positioning System (SSPS) that focuses on the patients facial contours which are relevant for a precise repositioning.The ultra-light and extremely rigid cradle can be clicked on the baseplate in seconds and forms a rigid link between mask and baseplate. The mask is limited to the relevant boundaries of the patients facial contours. By fixing the mask to the rigid carbon fiber cradle instead of pulling it down to the baseplate, the mask remains compact and will not be overstretched. This will clearly contribute to the stability of the patient set-up.The SSPS differentiates itself by an improved mechanical approach resulting in better rigidity. It combines easy handling with set-up stability, precision and reproducibility. The SSPS is an innovative and state of the art solution for precise radiotherapy in the head, neck and shoulder region.Patent pending

The SSPS features:

• A standard carbon fiber cradle that can be combined with MacroMedics MaxSupport head supports
• Optional: set of 4 cradles with integrated wedges of 5, 10, 15 and 7 inclination wedge
• Optional: set of 2 cradles with integrated blocks of 15 and 30mm height
