Philips Medical Systems has released AcQSim3, a new version of the Andover, MA-based vendor’s CT simulation workstation. AcQSim3 combines the CT simulation features of AcQSim with the firm’s Pinnacle3 radiation therapy planning (RTP) system on a single platform.
The system can function as a stand-alone CT simulation workstation, compatible with Philips’ multimodality imaging systems as well as third-party DICOM-compliant imaging systems, Philips said. It can also communicate with RTP systems from other vendors via standard DICOM and DICOM-RT transfer protocols.
Unique features available with Philips CT scanners include absolute patient marking, by which users can scan patients without fiducial markers by marking the actual treatment isocenter at scan acquisition. A digital pixel ray tracing feature allows for creation of digitally reconstructed radiographs (DRR), which enable users to examine 3-D CT data from any angle, Philips said.
Via a volume of interest (VOI) capability, AcQSim3 can render partial data volumes when performing simple fluoroscopy simulations, Philips said. Digitally composited radiographs (DCR), a work-in-progress capability for AcQSIM3, can simultaneously display vascular, soft-tissue, bony, and abnormal structures, allowing higher tumorcidal radiation doses to the cancerous area while sparing normal tissue, according to the vendor. DCR will be available in 2004.
