How the GaGe Digitizer was used: The GaGe digitizer used in the research is the CompuScope 12400. This 12-bit data acquisition card was crucial in the analog-to-digital data conversion and data transfer to a computer during the testing of the ultrasound transducer. It operated at a sampling frequency of up to 400 MHz, ensuring precise and accurate digital representation of the analog signals received from the ultrasound transducer during experiments.
How the GaGe Digitizer was used: The researchers employed bi-stage temporal sequences of HIFU transmission patterns on anaesthetized rats, monitored in real-time using ultrasound imaging and ECG. By controlling the timing and location of ultrasound exposure, they aimed to induce ventricular contractions effectively.

How the GaGe Digitizer was used: The GaGe Digitizer was employed to digitize ultrasonic
signals received from the lens at a high sampling rate. This allowed for the detailed analysis
necessary for creating Nakagami parametric images.
How the GaGe Digitizer was used: The GaGe digitizer played a crucial role in the experimental setup for measuring the pulse-echo response of the transducer array elements. The digitizer sampled the receiver output at a high frequency (1 GHz), capturing detailed data about the ultrasound signals. This data was essential for analyzing the performance improvements brought by the new fabrication methods, such as the use of glass microspheres in the backing material.
