How Does an Ultrasound Machine Work?

Ultrasonography is a non-invasive medical imaging technology that provides real-time images of internal organs required for various diagnostic purposes. High-frequency sound waves bounce off internal structures and generate an imaging model on the screen. 

Ultrasound machines can generate 2D, 3D, doppler, or contrast-enhanced images based on the type of the machine you’re using. Here, you will learn about the basic components, the exact working process of Philips Epiq 7C, and the major differences among common ultrasound machines. 

Basic Components of an Ultrasound Machine 

Transducer 

The transducer, also known as the probe, is the basic component of any ultrasound machine. It converts electrical energy into high-frequency sound waves that penetrate the body and reflect as echoes. There are three different types of transducers as linear, curvilinear, and phased array probes. 

Linear probes use flat, rectangular-shaped crystals for imaging superficial structures like blood vessels, thyroid, and muscles. However, curvilinear probes use curved arrays of crystals and provide a wide image in contrast to linear probes. These probes are ideal for abdomen and pelvic region ultrasound.

Meanwhile, phased probes are usually flat and use flat crystals just like linear ones. But send focused, directional beams that penetrate deeper inside the body and are ideal for imaging confined cavity spaces live chest cavity. 

Pulse generator

The pulse generator facilitates the working of a transducer by creating electrical pulses. These electrical pulses are converted into high-frequency sound waves by transducers that bounce off internal organs and create imaging models. The pulse generator also controls the intensity and frequency of the ultrasound signals. 

Scanner

The scanner controls the movement of a transducer. It ensures the transducer is positioned correctly with the right angle. Also, a scanner uses electronic beams to scan different angles and create a full view thus providing the best quality examination. 

Processor

The processor collects electrical signals from the transducer and converts them into digital images. The monitor displays the images and allows the examiner to change the position of the transducer accordingly. Thus, it improves the resolution and the clarity of an ultrasound image. 

Monitor 

Monitor displays the digitally produced images and helps clinicians assess the internal structures of the body. Modern monitors assist in real-time diagnosis and treatment planning by displaying clear, detailed images. 

Working Process of Philips Epiq 7C Ultrasound Machine 

Philips Epiq 7C is an advanced ultrasound machine designed for high-end imaging and diagnostic purposes. Medical lab technologists use it to diagnose or monitor various medical conditions related to the pregnancy, abdomen, and heart. Here’s the exact step-by-step working process of Philips Epiq 7C.

Transmission 

The pulse generator produces high-frequency electrical pulses and sends them to the transducer. The PureWave transducer of Philips Epiq 7C is well-known for its image quality and penetration rate even for complex patients. It converts electrical pulses into sound waves that penetrate deep into the body. 

Reflection 

The sound waves bounce back after hitting the lining of the internal organs or body cavity. The transducer receives those reflected sound waves as echoes and converts them into electrical signals. 

Processing 

The transducer sends those electrical signals to the processor. The nSight imaging technology of the processor uses contrast and spatial resolution to analyze the received electrical signals and create high-quality images. 

Image Display 

The monitor displays high-quality images created by the processor so the examiner can propose the best diagnostic or treatment plan based on the real-time view. 

The Shear Wave Elastography (SWE) of Philips Epiq 7C measures tissue stiffness, however, the Anatomical intelligence (AI) facilitates automated image analysis and annotation. Along with the color and spectral Doppler features, the contrast-enhanced technology uses contrast agents to enhance the image quality.
