collaborated to make radiation field datasets scanned with the dosimetry system compatible for use with the Memorial Sloan Kettering treatment dose calculation service, a project which later evolved into its first own radiation treatment planning software, RTP-123, released in 1987. Subsequent product generations included RTP/2, DSS (Decision Support System), DSS/2, DSS/3 3D for CRT and RTSuite. Accident A software product of the company was involved in an accidental overexposure of patients in Panama in 2001 when the treatment planning software RTP/2 (vers. 2.11, 1991) reportedly contributed to 28 patients receiving excessive amounts of radiation at the Instituto Oncologico Nacional in Panama City. At least eight patients died, while another 20 received overdoses likely to cause significant health problems. The physicians, who were legally required to double-check the computer's calculations by hand, were indicted for murder. A panel of experts designated by the International Atomic Energy Agency delivered a comprehensive report in August 2001, finding that the software permitted incorrect forms of data entry which in turn had led to miscalculation of treatment times. Multidata began a recall and in-field correction of its radiation treatment planning software in September 2001 with the issue of a software correction and detailed description of the cause and circumstances of the incorrect data entry.
