DSPS ® Double Shell Positioning System

Double Shell Positioning System


The MacroMedics® DSPS® Double Shell Positioning System strikes the perfect balance among the often-competing aspects of patient comfort, accuracy² and throughput. Docking to most common manufacturer’s head & neck baseplates, the DSPS concept is created around an ultra-light carbon fibre cradle with low attenuation.

The DSPS features:

  • Accurate, individually mouldable system
  • Quick and easy patient set-up
  • Comfortable2 for the patient, also during longer treatments
  • Allows fully customised prone positioning*
  • Different versions available for most common head & neck systems
  • MR safe cradles are available

The DSPS system consists of two masks made of special thermoplastic materials and therefore the patented material of the occipital mask is rigid enough to hold the patients head during moulding. There is no need for an additional head support and there is full access to customise the mask around neck and occipital bones. The facial mask is not overstretched and therefore extremely rigid. Both masks do not shrink resulting in a comfortable set-up for the patient.

The advanced double shell design enables the clinician to achieve high precision positioning for stereotactic cases, creating a new standard of accuracy² in frameless stereotactic radiosurgery.
