Introduction

For electron accelerators for the purpose of radiotherapy, if the device that transmits the dose to the patient fails, or the device design does not meet the electrical requirements:

In accordance with the requirements of mechanical safety standards, patients may be injured during use: If the equipment itself cannot adequately control the radiation, or the design of the treatment room Inappropriate, it may also injure other people nearby:

This part sets out the requirements that manufacturers who design and manufacture electron accelerators for radiotherapy should comply with, but it is not an attempt to specify accelerators:

Optimal performance requirements: The purpose of this section is to determine the current design points to be considered for the safe operation of such equipment: This section sets the If the performance of the equipment is lower than these limits, it can be considered that the equipment is in a certain fault state: At this time, the interlocking device should Action to prevent the equipment from continuing to run:

In order to ensure basic performance and avoid unsafe conditions, if the limit in:201:10 is exceeded, the interlock will prevent, interrupt or terminate the irradiation:

Each requirement specifies the type test (completed by the manufacturer) and/or field test (not necessarily completed by the manufacturer): Of course, according to the system According to the agreement between the manufacturer and the user, the field test may or may not be completed by the manufacturer:

Considering that the manufacturer cannot provide field test data before the equipment is installed, the data measured in the field test should be in the form of the field test report:

Type, compiled into the accompanying documents by the on-site installer of the equipment:

GB 15213 is the performance standard for electron accelerators used in radiotherapy:

Medical Electrical Equipment Part 2-1: Energy is Basic safety of 1MeV to 50MeV electron accelerator and basic performance specific requirements

201.1 Scope, purpose and related standards Except for the following, general standard 1) Chapter 1 applies:

201.1.1 Scope

replace:

This section applies to the basic safety and basic performance of therapeutic electron accelerators with energy from 1MeV to 50MeV, hereinafter referred to as ME equipment:

This part includes type tests and field tests, which are applicable to the manufacture and certain installation aspects of electron accelerators:

---It is intended to be used in radiotherapy in human medical practice, including the ability to automatically control its operation by the programmable electronic subsystem (PESS) Parameter selection and display equipment:

---Under normal conditions and in normal use, the X-radiation beam and (or) electron radiation beam output by the device:

- The nominal energy is 1MeV to 50MeV;

- At 1m away from the radiation source, the maximum absorbed dose rate is between 0:001Gy·s-1 and 1Gy·s-1;

- The normal treatment distance (NTDs) is between 0:5m and 2m from the radiation source:

at the same time,

---Expected to be used for:

- For normal use, under the guidance of the corresponding licensed or qualified personnel, it is necessary to have the skills required for special medical applications Operated by operators for specific clinical purposes, such as fixed radiation therapy or moving beam radiation therapy;

- Maintain according to the method recommended in the instruction manual;

- Regular quality assurance and calibration inspections by qualified personnel:

Note 1: In this section, all involved installation refers to the installation at the location of the responsible party:

Note 2: All the absorbed doses involved in this section refer to the absorbed dose in water:

GB/T 18987-2015 gives the naming of the equipment movement, the marking of the scale, their zero position and the direction of the movement increase value:

Guide (see:201:7:4:11):

GB 15213 specifies methods for testing and publishing the functional characteristics of medical electron accelerators: The purpose of this standard is to facilitate different manufacturers Comparison between accelerator-based ME equipment: GB 15213 does not include safety requirements, so it does not need to be consistent with this section: this in addition, it should also be noted that the test specified in GB 15213 does not guarantee that a medical electron accelerator meets the claim during its working life:
