Relocation of a nucletron microselectron-HDR brachytherapy system

Journal Article:

Abstract

Full text: For a period of four weeks, our clinical Nucletron microSelectron high dose rate (HDR) brachytherapy system was pulled out of clinical use and relocated to a new building. During this period decommission tests, de-wiring of the treatment unit and its associated safety system (such as radiation detector, emergency off circuits and door interlocks), transportation of all equipment, re-wiring of this equipment in the new location and recommission tests were carried out. The decommission and recommission test program was designed upon consultation with the manufacturer's (Nucletron) acceptance test procedures and work carried out by others. The ACPSEM tolerances for remote afterloaders was used as a guideline. In addition to mandatory dosimetry, positional, workstation database and safety tests, two Australian Standard compliance tests were carried out. The compliance tests involved one for remote afterloaders and another for treatment room design. This testing program was designed and implemented with the aim of ensuring ongoing safe delivery of brachytherapy doses to the patient. The testing program consisted of two parts. The first involved a series of decommissioning tests that consisted of dosimetry tests such as source and check cable positional accuracy and source calibration tests. In addition to these tests an inventory  More>>

This testing program was designed and implemented with the aim of ensuring ongoing safe delivery of brachytherapy doses to the patient. The testing program consisted of two parts. The first involved a series of decommissioning tests that consisted of dosimetry tests such as source and check cable positional accuracy and source calibration tests. In addition to these tests an inventory of standard plans, patient records and system configuration information was catalogued. The second part involved a series of recommission tests and involved carrying out dosimetry tests on the brachytherapy system (positional accuracy and calibration tests), simulating common treatment scenarios (prostate, cervical, vaginal and bile duct) and checking standard plans; patient records and system configuration had remained unchanged. During this period, other tests were carried out. These included Nucletron acceptance and preventative maintenance tests, Australian Standards compliance testing and integrity of network transfer of brachytherapy plans tests. There were no identifiable changes to the mechanical performance of the treatment unit.Correct functional performance of the workstation database, safety interlocks and network transfer of treatment plans was demonstrated. Standard treatment simulations indicated no unusual outcomes. The Nucletron microSelectron HDR remote afterloader meets Australian Standard compliance. The treatment suite meets Australian Standards compliance except for radiation signage, which is currently being addressed. The relocation of the Nucletron MicroSelectron-HDR brachytherapy unit did not introduce any changes to the system. Compliance with the relevant Australian Standard was determined. The system was successfully released for clinical use within the planned time frame. Copyright (2004) Australasian College of Physical Scientists and Engineers in Medicine.}
