The thermal index (TI) has been used as a relative indicator of thermal risk during diagnostic ultrasound examinations for many years. It is useful in providing feedback to the clinician or sonographer, allowing assessment of relative, potential risk

Intracoronary ultrasound (ICUS) is often used in studies evaluating new interventional techniques. It is important that quantitative measurements performed with various ICUS imaging equipment and materials are comparable. During evaluation of quantit

Background —Ultra–high-frequency (40- to 50-MHz) intravascular ultrasound (IVUS) improves image quality compared with conventional 20- to 30-MHz IVUS. However, as the frequency of IVUS increases, high-intensity backscatter from blood components m

The need to further improve the spatial resolution of intravascular ultrasound (IVUS) may drive the transducer center frequency even higher than the current 40 MHz range. Using a higher frequency results in stronger scattering echoes from the blood a

One common approximation for a field point located in the far field of the transducer is to trapezoidally-shaped function to approximate the true spatial impulse response. A quadrilaterally shaped function is proposed here. The quadrilaterally shaped

The method of backpropagation is used to estimate the range between two planar surfaces. This method is shown to be more tolerant in a noisy environment than another method that uses the spatial derivative of the measured wave field to estimate the r
