    EVALUATION SUMMARY: IN MOSAIC IMAGES FROM SIEMENS MR MACHINE, THERE'S AN OPTION TO REVERSE THE SLICES WITHIN THE MOSAIC IMAGE. THIS IS NOTED WITHIN A PRIVATE TAG IN THE HEADER. IN THE SOFTWARE INVOLVED THE INTERPRETATION OF THIS HEADER HAS NOT BEEN COMPLETELY CORRECT AND THIS MAY LEAD TO SITUATIONS WHERE THE SLICES MAY BE REVERSED. THIS HAPPENS WHEN THE IMAGES HAVE BEEN SET UP FOR REVERSAL, AND THE REVERSAL IS SPECIFIED TO BE IN A DIFFERENT DIRECTION THAN THE DATASET IN QUESTION. THE CONSEQUENCES OF THIS ERROR MY BE LEFT-RIGHT, UP-DOWN AND ANTERIOR-POSTERIOR FLIPPING OF THE IMAGES.

    Description of Event or Problem · 1

    THE PROBLEM WAS DETECTED BY AN ENGINEER WHEN HE TESTED THE SOFTWARE PRODUCT (B)(4) AS AN EVALUATION OF THE SOFTWARE'S CAPABILITIES BEFORE BUYING THE PRODUCT. THE BUG HE DISCOVERED HAS ITS ROOT IN SOFTWARE CODE THAT IS SHARED BY THE SOFTWARE PRODUCT CALLED (B)(4), AND THE ERROR IS THEREFORE ALSO PRESENT IN THIS PRODUCT. THE BUG WAS INTRODUCED IN (B)(4) AND EXISTS IN THE LATER VERSIONS (B)(4). THE BUG WAS INTRODUCED IN (B)(4) AND EXISTS IN LATER VERSION (B)(4). THESE SOFTWARE PACKAGERS HAVE BEEN IN USE AT MANY SITES WHERE THEY HAVE BEEN USED FOR ANALYSIS OF IMAGES FROM SIEMENS MACHINES USING THE MOSAIC FORMAT. HOWEVER, NO OTHER REPORTS HAVE BEEN RECEIVED BY THE MANUFACTURER ON THIS PROBLEM. WE THEREFORE BELIEVE THAT THE SPECIAL CONFIGURATION FOUND IN THE HEADER OF THE IMAGES FOR WHICH THE SOFTWARE SET UP A WRONG GEOMETRY IS VERY UNUSUAL. ANYWAY, TO AVOID POSSIBLE MISINTERPRETATIONS OF IMAGE DATA WITH REGARDS TO WHERE A CERTAIN ANATOMICAL STRUCTURE IS LOCATED, WE SENT WARNING LETTERS TO ALL OF OUR CUSTOMERS. THE NEXT STEP FOR US WILL BE TO FIX THE SOFTWARE AND RELEASE A NEW VERSION. HOWEVER, TO DO THAT WE NEED TO OBTAIN MORE INFORMATION FROM SIEMENS ABOUT THE INTERPRETATION OF THE HEADER INFORMATION IN THE IMAGES.
