SU‐GG‐T‐533: Remote PC Application Access to a Stereotactic Treatment Planning System SQL Database

Purpose: To implement remote access using Matlab to a PostgreSQL database, which supports the Leksell GammaPlan (LGP) version 8.1 treatment planning system. Method and Materials: A postgreSQL Java Database Connectivity (JDBC) driver was downloaded from the official website of postgreSQL. The class path that specifies a series of files and directories, pointing to classes accessible to Matlab, must be edited to include the database driver. Table patients maintains information on patients. Table examinations maintains information on each examination. Table skulls maintains information on skull coordinates. Table plans minal information on each target. Table targets maintains information on each target. Table shots maintains information on each shot. lann examinations is related to table patients through examination ID. Table skulls is related to table examinations through examination ID. Table plans is also related to table examinations through examination ID. Table targets is related to table plans through plan ID. Table shots is related to table targets through target ID. Results: An application was implemented in Matlab. By entering the patient ID, any information about any treatment performed on any specific patient, from patient's name and birthday to the shot time of each shot, could be retrieved remotely on a PC from the database in a well‐maintained data structure. The retrieved data were further used to verify LGP treatment plans through independent dose calculation and display. Conclusion: A remote access to PostgreSQL database behind LGP is feasible in Matlab. Similar application could also be implemented in other environments like Visual C#. It is of great convenience for users who desire to develop their own applications that use information found in the LGP SQL database.
