VolumeView™

3D volumetric imaging

  

Elekta Synergy® VolumeView™ provides low dose volumetric 3D data sets with submillimeter isotropic resolution, acquired with the patient in the treatment position. The system can acquire a complete 3D volume in a partial or complete gantry revolution, with reconstruction taking place simultaneously.

The 3D reconstructed VolumeView™ image is available for review and registration immediately following acquisition. Comprehensive workflow tools support the acquisition and subsequent review of the 3D volume images. Advanced automated registration tools allow rapid registration against the CT treatment plan image. This allows for optimization of the treatment plan and correction for target shifts due to organ motion and deformation.

This entire process will add only around 5 minutes to the patient's appointment time. This can be evidenced from the timings stated in our clinical case studies (see links on right).

 

The dosage necessary to obtain a VolumeView image can be varied depending on the level of contrast required. For prostate imaging, a larger degree of contrast is required to differentiate similar soft tissues in addition to complications caused by low transmission and high scatter, while a VolumeView image in the head and neck region would require a lower dose, in the region of 0.9mGy CTDIw.

Key visualization advantages offered by VolumeView imaging at the time of treatment include:

  • soft tissue size, shape and position
  • critical organs and tumors
  • bony anatomy and alignment in 3D
  • eliminates the need for surrogate markers
  • ability to minimize the imaging dose
  • overlay of structures defined in treatment planning system
  • large field-of-view
  • simultaneous acquisition and reconstruction.
