Captus 4000e Thyroid Uptake System

Request a Quote

The Captus 4000e unit is a comprehensive Nuclear Medicine Measurement System, with specific software modules for thyroid uptake, bioassay, wipe tests, automated quality assurance tests, and isotope library. The system includes a fully functional 1024 channel MCA with auto and manual calibration. Timed activity mode features a programmable repetitive timed measurement program.

Improved menu driven workflow and large 20 inch color touch screen streamlines user interface.

The optional fully integrated DICOM interface communicates directly with hospital information systems, and can transfer patient, wipe test, and QC data. Custom Protocol is included as standard, and Microsoft Office Professional 2010 software is optional.

New and improved stand provides ergonomically adjustable monitor and easy to position articulating collimator arm. Four sided comfortable handle grips and swivel wheels ensure easy mobility. PC can be attached to either right or left side to optimize workspace.

DICOM Software (Optional)

ITEM # 5430-00007

DICOM software adds DICOM Modality Worklist (MWL) and DICOM export to the Captus 4000e system. This solution allows patient information and demographics to be pulled from the Radiology Information System (RIS) or Hospital Information System (HIS), thus, reducing errors and time associated with the manual input of patient information.

Cap-DICOM software creates a DICOM secondary capture image from information generated during the uptake procedure. The software exports the DICOM image files to a destination DICOM C-Store provider specified by the user. This destination may be a nuclear medicine workstation or PACS (Picture Archive and Communication System).
