About this file
This is a Questions and Answers document clarifying CT scanner requirements for a radiation oncology acquisition.
The Government requires a commercially available 3-Dimensional CT Scanner capable of performing 2D X-ray scout imaging and 3D CT imaging to support radiation oncology treatment planning workflows. The minimum specification is a 64-slice CT scanner. The system must support 4DCT imaging to manage respiratory motion and quantify target and organs-at-risk motion, with respiratory gating and motion management included as part of the 4DCT requirement. Images must be exported in DICOM-RT format for compatibility with the Eclipse Treatment Planning System. The CT scanner must feature a large bore configuration with a minimum size of 80 centimeters and a flat tabletop compatible with CIVCO immobilization devices. These requirements are defined in PWS Sections 5, 6, and 7, with detailed simulation and treatment-planning capabilities specified in PWS Section 7.a.

QUESTIONS AND ANSWERS
QUESTION:
We would appreciate clarification regarding the “CT Simulation” requirements referenced in the Statement of Work.
Specifically, we would like to confirm whether the Government requires:
• a dedicated radiation oncology CT simulator system, or
• a standard diagnostic 64-slice CT system configured to support radiation oncology treatment planning workflows.
Could you please clarify whether the required system must support the following:
• 4DCT
• Respiratory gating
• DICOM-RT export
• Eclipse Treatment Planning compatibility
• Large bore configuration
• Flat tabletop for immobilization devices
• Any other CT Scanner imaging acceptable?
GOVERNMENT RESPONSE:
The requirements for this acquisition are defined in PWS Sections 5, 6, and 7. The Government requires a CT system to support radiation oncology treatment planning workflows. The CT system provided must fully support Radiation Oncology CT simulation workflows as described in the PWS.
System Type
The PWS specifies a commercially available 3-Dimensional CT Scanner (3D CT Scanner) capable of performing:
• 2D X-ray scout imaging
• 3D CT imaging
• 4DCT imaging
(PWS section 5)
The system must be a minimum 64-slice CT scanner.
(PWS section 7.a)
Required Simulation and Treatment-Planning Capabilities
Based strictly on PWS section 7.a, the system must support:
• 4DCT
The system shall “manage respiratory motion (4DCT) to quantify target and organs-at-risk motion.”
• Respiratory Gating / Motion Management
Included as part of the 4DCT respiratory-motion management requirement.
• DICOM-RT Export
“Images must be DICOM-RT to be transferred to the Eclipse Treatment Planning System.”
• Eclipse Treatment Planning System Compatibility
DICOM-RT–formatted images must be compatible with the Eclipse TPS for treatment planning.
• Large Bore Configuration
“Large Bore Size: 80 cm (minimum).”
• Flat Tabletop for Immobilization Devices
“Flat Tabletop compatible with CIVCO immobilization devices.”
