Legacy data conversion tool (PSC)

Based on an automated process and simple user interface, converting older patient records is straightforward. Patient records created with LGP 4.xx, 5.xx and 4C are first copied from archiving media (DAT tapes and Magneto-Optical disks) onto a network disk (NAS) using a special UNIX application (rescue tool).

Once copied, the second step includes the conversion of rescued patient records onto an external USB disk connected to the customer PC-Linux primary LGP. The last step is to import converted patient records into the patient database using the import function.

The legacy conversion tool is not available for customer where a translated versions of LGP is required (EU).

Included items:

o One Network disk used to copy records from DAT tapes and MO disks

o One USB external disk used to convert records from network disk

Software and instructions to perform the rescue and conversion of patient records.

LGP – DICOM RT License

DICOM RT provides an exclusive possibility to share treatment information with any DICOM RT compatible system. It includes:

IMPORT of DICOM RT STRUCT allows displaying any user-defined region/volume created on a DICOM RT system. Volumes can be target volumes, organ at risks, isodoses or any other region of interest defined by the user.

EXPORT of treatment data via DICOM RT STRUCT and DICOM RT DOSE allows sharing information with any compatible systems to perform dose comparison or dose addition.

Accessories for Leksell Gamma Knife® PERFEXION™

1	Leksell Gamma Knife® Dosimetry Phantom

The Dosimetry Phantom is used for accurately measure absorbed dose and dose rate in Leksell Gamma Knife®. Three adapters for measuring with ionization chamber or other detectors are included. The Dosimetry phantom can also be used to verify dose 3D distributions by means of film dosimetry. The dose distribution position is defined by accurately positioning the films in the phantom using two rods.

1	Film Holder Tool

The Film Holder Tool is used for measuring the dose delivery accuracy in Leksell Gamma Knife® by comparing the location of the patient positioning system calibration center point and the radiological focus point within the treatment unit.
