35、10 Table A.1 Table indicating correlation 24 BS EN 62083:2009 6 62083 IEC:2009 INTRODUCTION A RADIOTHERAPY TREATMENT PLANNING SYSTEM (RTPS) is a device, usually a PROGRAMMABLE ELECTRICAL MEDICAL SYSTEM that is used to simulate the application of RADIATION to a PATIENT for a proposed RADIOTHERAPY TRE
36、ATMENT. It usually, but not necessarily, provides estimates of ABSORBED DOSE distribution in human tissue using a particular algorithm or algorithms. These estimations, referred to in this International Standard as ABSORBED DOSE distributions, are used by a QUALIFIED PERSON in planning a course of R
37、ADIOTHERAPY. The output of an RTPS is used by appropriately QUALIFIED PERSONS as important information in RADIOTHERAPY TREATMENT PLANNING. Inaccuracies in the input data, the limitations of the algorithms, errors in the TREATMENT PLANNING process, or improper use of output data, may represent a safe
38、ty HAZARD to PATIENTS should the resulting data be used for TREATMENT purposes. This standard defines requirements to be complied with by MANUFACTURERS in the design and construction of an RTPS in order to provide protection against the occurrence of such HAZARDS. SPECIFIC types of input data and ca
39、lculation algorithms are not addressed in this standard. These are dependent on many factors, such as available technology, RESPONSIBLE ORGANIZATION preference, and the type of TREATMENT being planned. However, this standard establishes the safety requirements that are common to algorithms. It also
40、establishes the minimum requirements for the contents of the ACCOMPANYING DOCUMENTS that will permit the OPERATOR to make informed choices during the TREATMENT PLANNING process. Generally, an RTPS is not used in the presence of PATIENTS, so it is not MEDICAL ELECTRICAL EQUIPMENT as defined by IEC 60
41、601-1. Consequently, this standard is written in an independent format rather than as a particular standard to IEC 60601-1. Relationship to other standards The BASIC SAFETY of hardware, such as for protection against electric shock and fire, and for assuring ELECTROMAGNETIC COMPATIBILITY requires th
42、at these subjects be addressed by the MANUFACTURER through compliance with an appropriate standard, depending upon the nature and environment of the hardware used for the RTPS. See Annex A for hardware safety standards. A RTPS is principally a software application for medical purposes. IEC 62304 app
43、lies (see Clause 14). IEC 61217 gives guidance on the designation of ME EQUIPMENT movements, the marking of scales, their zero position and the direction of movement with increasing value. The means of applying IEC 61217 are SPECIFIED in appropriate clauses and subclauses of this standard. IEC 62366
