Ultrasound Machines

Ultrasound is a type of sound wave. High frequency sound waves generated by piezoelectric effects are sent back to the ultrasound machine and appear as images, called sonograms. Frequencies range from 20kHz upwards. Images are generated by the sending of pulses from the ultrasound probe (also known as “transducer”) which is placed directly inside the body (endocavitary probes – which are inserted in the vagina, oesophagus or rectum, or intraoperative probes which are used during operation in theatre). Aside from endocavitary and intraoperative probes, some probes such as linear probes, are placed directly onto the patient’s skin. The process is as follows: sound waves travel through the body, with a certain percentage being reflected to the probe and others travelling to other tissue parts. The image (sonogram) then shows the ultrasound waves which are reflected to the probe. This process is undertaken by the CPU, by which the distance from the tissue/specific organ is calculated by comparing the speed of sound (in tissue – 1540 m/s) and the time by which each echo returns. The resulting image (in 2D) is based on distances and distances and the signal intensity of the echoes which have been reflected. This is an introductory insight to ultrasonography, but there are of course more detailed explanations, which are explained below.

Standard Probes

Linear – for MSK, vascular, thyroid, testes, penile, mammography, small parts, pediatrics

Convex – for obstetrics, gynaecology, abdominal, pediatrics, neonatal, kidneys, urology

Phased-Array (aka “sector-array”) – for cardiology, intracranial, some small parts, lungs

3D/4D Probes

Endocavitary 4D – for urology, gynaecology, obstetrics

Convex 4D – for abdominal, gynaecology, obstetrics, urology

Laparoscopic Probes

Intraoperative probes

TEE Probes

Transoesophageal probes – for cardiology
