pin code-273012 - North Eastern Railway - Indian Railway

- Specify DRR image enhancement tools to improve DRR image quality Reconstruction
of DRRs should be real- time or sub-second Direct printing of DRR on laser film should
be possible.
- Real-time displays of DRR as beam parameters are changed.
- It should be possible to transfer DRR and BEV images to EPID of Linear Accerlator.
- Depth Control in oblique projections must be possible
- Cross-hair display on DRR to provide scale information.
SUPPORT OF ASSYMMETRIC COLLIMATORS AND MULTILEAF COLLIMATORS
(MLCs):
- It should be possible to define this asymmetric collimator feature, where both the X-
and Y-pairs of jaws are asymmetric. The software should allow multi-leaf collimator
placement up to 60 pairs or more.
Isocenter management:- The software should support separate isocenters for multiple target
volumes or general regions.
- Marked and final isocenters should be reported and displayed in the Localization
package for easy confirmation of a physical simulation session.
- Hardcopy of the isocenter coordinates should be possible for record of the simulation
session.
- No limit on number of isocenters per target.
VOLUME RENDERING
- 3D view and volume rendering capabilities
- Post processing features like Volume Rendering, Real-time multi-axial volume
reconstruction, - 3D surface rendering, Color 3D should be available.
- It should allow complete 3D volume to be defined including complex 3D volumes, user
selectable multi-images views, Beams Eye View, DRR etc.
Data Import / Export
- System should be able to export Image, volume and plan data in DICOM 3.0 standard
along with all Radiotherapy specific data and private objects, DICOM RT plans and
data sets.
- System should be able to import DICOM RT data.
- Dose Module should consist of two different types of calculation algorithm namely
Collapsed Cone Convolution algorithm for photon beam dose calculation
- Pencil Beam algorithm for Photon beam dose calculation
- It should be possible to define the absolute dose to a specified point for each beam or
MUs or time (isotope base machines).
