Transcranial doppler machine1/25/2024 ![]() ![]() They are the same transducers generally employed for cardiac and abdominal images for adult, pediatric and neonatal patients.Ībsolute Medical Equipment recommendations consider a variety of factors before suggesting an ultrasound machine that best suits your demands. The probes that are capable of providing images for TCD are the phased array/sector array transducers. Any other brain related trauma or ailment that results from a lack of or excess blood flow can be diagnosed and prevented with the use of transcranial doppler ultrasound imaging.Ĭonsidering the fact that one is diagnosing the vessels in one’s brain, the ultrasound transducer that is capable of producing images for this application must have a low frequency range (the lower the frequency range the deeper the potential penetration). Transcranial doppler ultrasound is also known as TCD, and is often employed during a stroke, or to determine whether a patient is at risk of suffering from a stroke. Like all other doppler imaging, the imaging is not of a particular structure, but of blood flow through veins and vessels. It is used to display the circulation and blood flow that occurs within the brain (hence the cranial in transcranial). Transcranial doppler is a specialized type of ultrasound application. Instead, these applications are very specific and refer to very a precise type of medical diagnosis procedure. These applications are not quite as general as, say, the abdominal application, which has subcategories under “abdominal” – kidney and liver for example and refers to a region. This particular article will focus on understanding specialized applications: transcranial doppler, elastography, and stress echo. (n.d.).Our “Understanding Ultrasounds” blog series has been primarily focusing on understanding integral ultrasound applications, along with elaborating on the best transducers and ultrasound systems available for each application.

Typically, a healthcare provider recommends a Doppler ultrasound if a person shows signs or symptoms of certain conditions, such as peripheral arterial disease.
