Full title and description
Ultrasonics - Fields - Guidance for the measurement and characterization of ultrasonic fields generated by medical ultrasonic equipment using hydrophones in the frequency range 0,5 MHz to 15 MHz (IEC TS/TR 61220:1993). The document gives practical guidance and simplified procedures for measuring acoustic output from medical ultrasonic equipment and for correcting measurement limitations introduced by hydrophones of finite bandwidth and finite active element size.
Abstract
This technical specification/report provides measurement guidance for characterizing ultrasonic fields produced by diagnostic and related medical ultrasound equipment in the 0.5–15 MHz band. It describes recommended measurement techniques using hydrophones, recommended parameters to report (field, pressure, intensity-related quantities), and correction procedures to mitigate hydrophone bandwidth and spatial‑averaging effects. The publication was prepared by IEC TC 87 (Ultrasonics).

Scope
The document provides guidance on practical measurement of the acoustic output of various types of medical ultrasonic equipment using hydrophones in the frequency range 0.5 MHz to 15 MHz. It includes measurement set‑ups, choice of hydrophone and positioning, limitations due to finite hydrophone bandwidth and finite active element size, and procedures to correct or compensate for those limitations when characterizing fields. It is intended as measurement guidance rather than as a mandatory test standard.
Key topics and requirements
- Measurement methods for ultrasonic fields generated by medical devices (pulse‑echo, pulsed Doppler, continuous‑wave where applicable).
- Use and selection of hydrophones for field mapping in 0.5–15 MHz.
- Procedures to correct for finite hydrophone bandwidth and spatial averaging (finite active element size).
- Recommended acoustic quantities to measure and report (pressure waveforms, spatial and temporal peaks/averages, derived intensity measures).
- Practical measurement set‑ups, alignment and positioning, and uncertainty considerations for hydrophone measurements.
Typical use and users
Used by biomedical/test engineers, ultrasound equipment manufacturers, calibration and test laboratories, academic researchers working on ultrasound metrology, and regulatory bodies needing reproducible field measurements for safety and performance assessment. Typically referenced when designing measurement campaigns or interpreting hydrophone data for medical ultrasound transducers and systems.
Related standards
This publication has been withdrawn and replaced by the IEC 62127 series (IEC 62127-1, -2 and -3, 2007) which cover hydrophone measurement methods and performance for medical ultrasound. National and regional adoptions and correlated documents include EN/IS/I.S. versions of IEC 61220 and later EN/ISO adoptions; related safety and performance standards include IEC 60601‑2‑37 (medical ultrasound equipment safety/performance) and other hydrophone calibration and measurement standards.

FAQ
Q: What is this standard?
A: IEC TS/TR 61220:1993 is a technical specification/report that gives guidance for measurement and characterization of ultrasonic fields produced by medical ultrasonic equipment using hydrophones in the 0.5–15 MHz frequency range.
Q: What does it cover?
A: It covers practical measurement procedures, selection and use of hydrophones, correction methods for hydrophone limitations (finite bandwidth and active element size), recommended measured quantities and reporting practices for medical ultrasound field characterization.
Q: Who typically uses it?
A: Biomedical engineers, ultrasound manufacturers, test and calibration laboratories, researchers in ultrasound metrology, and regulators or test houses concerned with acoustic output measurements.
Q: Is it current or superseded?
A: It has been withdrawn and superseded — IEC TS/TR 61220:1993 was replaced by the IEC 62127 series (parts 1–3) published in 2007; users should consult the IEC 62127 series for the current measurement and hydrophone standards.
Q: Is it part of a series?
A: It is a standalone technical specification/report that served as measurement guidance; its subject matter was later incorporated into and expanded by the IEC 62127 series (hydrophone measurement standards). It is also related to broader IEC work under TC 87 on ultrasonic measurement and calibration.
Q: What are the key keywords?
A: Hydrophone, ultrasonic field, acoustic output, medical ultrasound, field mapping, spatial averaging, bandwidth correction, measurement uncertainty, IEC 61220, IEC 62127.
