1. PURPOSE AND SCOPE

The purpose of this Standard Operating Procedure (SOP) is to establish the clinical standards, technical protocols, and safety requirements for all diagnostic ultrasound examinations performed at [____________________] (the "Facility"). This document applies to all sonographers, radiologists, and clinical staff authorized to perform, oversee, or interpret ultrasound procedures.

2. REGULATORY COMPLIANCE AND CREDENTIALING

All clinical personnel must maintain current certification from the [____________________] (e.g., ARDMS/ARDMS equivalent). Equipment shall be maintained in accordance with [____________________] (e.g., FDA/ISO/Local Health Authority) standards.

3. PRE-PROCEDURAL PROTOCOL

3.1. Patient Verification: Personnel must verify the patient’s identity using at least two (2) identifiers, including [____________________] and [____________________].
3.2. Indication for Exam: The written physician order must specify the clinical indication for the ultrasound. Any discrepancy between the order and the patient’s clinical presentation must be resolved with the ordering provider prior to initiation.
3.3. Informed Consent: For invasive ultrasound-guided procedures, a formal Informed Consent form must be executed by the patient or their legal representative and witnessed by [____________________].

4. CLINICAL EXECUTION STANDARDS

4.1. ALARA Principle: All sonographic imaging shall be conducted under the ALARA (As Low As Reasonably Achievable) principle, minimizing acoustic output and duration of exposure.
4.2. Imaging Parameters:

• System Preset: Utilize the facility-approved preset for [____________________] (e.g., Abdominal, Vascular, OB/GYN).
• Image Optimization: Adjust Time Gain Compensation (TGC), focal zones, and depth to ensure optimal diagnostic resolution.
• Documentation: A minimum of [____] representative images must be archived for each anatomical region examined.

5. SAFETY AND INFECTION CONTROL

5.1. Equipment Sterilization: Transducers must be cleaned and disinfected according to [____________________] (manufacturer or regulatory guidelines) between every patient encounter using [____________________] (e.g., high-level disinfectant).
5.2. Patient Safety: Standard Precautions shall be observed. In the event of an adverse reaction (e.g., contrast-related anaphylaxis), the facility’s emergency medical protocol shall be activated immediately.

6. REPORTING AND QUALITY ASSURANCE

6.1. Preliminary Findings: Sonographers may provide a technical report to the interpreting physician but shall not provide a formal diagnosis to the patient.
6.2. Final Reporting: The interpreting radiologist/physician shall finalize the report within [____] hours of study completion.
6.3. Quality Review: Random audits of [____]% of ultrasound examinations shall be conducted monthly to ensure compliance with image quality and documentation standards.
