3 12 mhz linear array transducer

Manufactured by Philips

Sourced in United States

The 3–12 MHz linear array transducer is a medical imaging device designed for a wide range of clinical applications. It operates within the specified frequency range and utilizes an array of piezoelectric elements to generate and receive ultrasonic waves. This transducer is intended for use with compatible ultrasound systems to capture high-resolution images of anatomical structures.

The abovementioned sonographic study protocol was applied. M-mode examinations of both CCAs were performed in long-axis view under three-lead ECG tracking using a 3–12 MHz linear array transducer (Philips Healthcare, Amsterdam, The Netherlands). The end-diastolic diameter (dD, mm) and end-systolic diameter (sD, mm) of both CCAs were measured offline on a separate workstation (IntelliSpace Cardiovascular Ultrasound Viewer, Philips Healthcare, Amsterdam, The Netherlands).
Stiffness index β was defined as [23 (link)]:

Stiffness Index β = \frac{\ln (\frac{SBP}{DBP})}{Δ D / dD}

Carotid Intima-Media Thickness Assessment

Check if the same lab product or an alternative is used in the 5 most similar protocols

At the level of carotid bifurcation, both CCAs were evaluated in long-axis view utilizing a 3–12 MHz linear array transducer (Philips Healthcare, Amsterdam, The Netherlands). Three consecutive loops were recorded under three-lead ECG tracing and transferred to a separate workstation (QLAB Cardiovascular Ultrasound Quantification Software, version 11.1, Philips Healthcare, Amsterdam, The Netherlands) for offline analysis. At end-diastole (R wave in ECG), the carotid intima-media thickness (cIMT, mm) was assessed semi-automatically for each side. The ROI was set proximal to the carotid bifurcation and the length was adjusted to 10 mm. Three measurements were performed on each side, and the average cIMT for the right and left CCA was calculated. Moreover, the mean cIMT value of both CCAs was assessed.

Extracranial high-resolution sonography of the carotid arteries was performed with Philips iU22 and 9–3 MHz linear array transducer. Two patients were examined at the intensive care unit with a portable Phillips CX50 ultrasound system and 12–3 MHz linear array transducer (both systems Philips Medical Systems, Bothell, WA, USA). Patients and controls were examined by two sonographers (AF, UWA), which both are trained and certified for the NOR-SYS duplex sonography research protocol in collaboration with the Vascular Imaging Centre, University Medical Centre, Utrecht, The Netherlands.

The 10 primary sonographically guided PSTJ injections performed in the Procedural Skills Laboratory were completed using an iU22 ultrasound machine and a 17-5-MHz linear array transducer (Philips Healthcare, Bothell, WA). The sonographically guided PSTJ injection performed for CT validation was completed using a CX50 portable ultrasound machine and a 12-3-MHz linear array transducer (Philips Healthcare). The CT-guided PSTJ injection and the CT scans after both the sonographically guided and CT-guided injections were performed using a Sensation 64 scanner (GE Healthcare, Waukesha, WI) with the following parameters: collimation, 12 × 0.3 mm; pitch, 0.8; reconstruction slice and increment, 0.4 to 0.6 and 0.2 to 0.6 mm; tube voltage, 140 kV (peak); and tube current, 250 mA. All injections were performed using 25-gauge, 38-or 50-mm stainless steel needles.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
