The primary purpose of the rate pulse control during angiography is to prevent forceful injection. This control mechanism allows the radiographer or practitioner to regulate the speed and pressure with which contrast media is injected into the vascular system. By managing this rate, the risk of complications from high-pressure injections, such as vascular trauma, extravasation, or discomfort for the patient, can be significantly reduced.

This is particularly important in angiography, where precise delivery of contrast agents is essential for achieving optimal imaging results while ensuring patient safety. Proper use of the rate pulse control contributes not only to the effectiveness of the procedure but also to the well-being of the patient throughout the imaging process.

While aspects like image quality, patient comfort, and minimizing radiation exposure are important considerations in imaging procedures, they are not the primary function of the rate pulse control during angiography. Instead, this control is specifically designed to manage the injection dynamics safely.
