Utilizes interactions between ultrasound physics and the acoustic properties of tissues/organs to generate 2D images. Enables real-time dynamic display of morphological structures and motion, allowing immediate observation of organ changes. Clearly visualizes internal organ contours, boundaries, size, morphology, and internal structures, critical for examining solid organs (liver, gallbladder, pancreas, spleen, kidneys) and cardiovascular structures.
Real-time color mapping of blood flow direction and relative velocity overlaid on 2D grayscale images.Color brightness indicates flow speed (brighter = faster), while color represents direction: red (toward the probe) and blue (away). Combines anatomical and hemodynamic information for comprehensive diagnostics.
Complements color Doppler by reducing angle dependency, eliminating aliasing, and enhancing sensitivity to low-velocity flow.The color bar lacks directional information, instead using color brightness to map blood flow energy intensity, offering a unique hemodynamic perspective.
M-mode ultrasound is based on the propagation of a single ultrasound beam within an animal body, where reflected echoes from tissue interfaces along the beam path are detected and one-dimensionally unfolded into time-varying curves.The x-axis represents time, while the y-axis indicates tissue depth. As anatomical structures move, the positional changes of reflected echoes over time generate continuous curves, thereby visualizing the motion dynamics of tissues or structures.
M-mode ultrasound excels in ultra-high temporal resolution, enabling precise capture of rapid structural motions, such as myocardial contraction and relaxation. The displayed curves allow direct measurement of parameters like ventricular chamber dimensions, wall thickness, and motion amplitude. Additionally, it calculates cardiac functional indices, including ejection fraction and fractional shortening, to assess heart performance. This modality also detects abnormal motion in large vessel walls.
Pulsed-Wave (PW) Doppler is a precise hemodynamic analysis technique that directs brief ultrasound pulses to a targeted vascular region and captures reflected echo signals in real-time, enabling detailed analysis of intravascular blood flow dynamics.During operation, users can flexibly adjust the sample volume and position it precisely within the target vessel. The system then acquires blood flow signals from this region and converts them into characteristic PW Doppler waveforms.These waveforms allow accurate quantification of dynamic parameters such as blood flow velocity and acceleration, as well as time-related measurements including flow duration and blood flow variations across cardiac cycles. The derived quantitative data provides critical diagnostic evidence for evaluating vascular patency, identifying flow abnormalities, and plays a vital role in diagnosing cardiovascular diseases, peripheral vascular disorders, and other conditions.
TDI leverages the Doppler effect to visualize tissue motion by capturing frequency shift signals generated by moving tissues.During signal processing, precise adjustment of gain parameters and deployment of low-pass filtering effectively filter out high-frequency, low-amplitude frequency shifts caused by intracardiac blood flow, retaining only low-frequency, high-amplitude signals from myocardial motion. These filtered signals are displayed via pulsed-wave Doppler in real time, providing intuitive visualization of ventricular wall motion velocity, direction, and segmental movement.Compared to conventional ultrasound imaging, TDI enables more detailed analysis of myocardial motion, offering critical insights for cardiac function assessment, myocardial pathology diagnosis, and treatment efficacy monitoring. It demonstrates distinct advantages in early detection of myocardial ischemia and evaluation of myocardial systolic/diastolic function.
This feature enables side-by-side comparison of historical research case data with current images or cross-animal image comparisons, facilitating real-time monitoring of experimental progression and dynamic changes. It streamlines data analysis by allowing researchers to instantly visualize temporal variations or intersubject differences, enhancing experimental control and insight generation.
During cardiac ultrasound examinations, the electrocardiogram (ECG) can simultaneously display the electrical activity of the heart.By observing waveform changes on the ECG, such as the P wave, QRS complex, and T wave, researchers can accurately determine the mechanical activity of the heart during different electrophysiological phases. This enables a more precise evaluation of cardiac chamber size, morphology, myocardial thickness, and valve motion.
Simultaneously, real-time monitoring of the animal's heart rate allows researchers to dynamically adjust anesthesia depth based on the heart rate, ensuring experimental safety. Additionally, maintaining consistent heart rate levels between experimental groups enhances the reliability and comparability of results. The rodent ECG module with thermal insulation function maintains body temperature during anesthesia, preventing hypothermia caused by anesthesia in laboratory animals.
VSpeckle (Speckle Reduction) technology employs advanced algorithms to accurately identify and effectively suppress inherent speckle noise in ultrasound images, significantly enhancing image clarity and contrast resolution.
It’s worth noting that this process may slightly weaken or obscure subtle structures. Users can conveniently adjust the speckle reduction level via the 2D touch panel menu using the arrows next to the VSpeckle (Speckle Reduction) button, enabling flexible switching from enhanced noise reduction to complete deactivation.
VFusion (Composite Imaging) intelligently enhances image contrast through advanced signal processing, accentuating grayscale differences between tissues, improving structural recognition, and precisely delineating organ boundaries with sharper details. This is particularly advantageous for vascular ultrasound diagnostics.
Users can easily operate this function via the 2D touch panel menu by adjusting the composite level with the arrows next to the VFusion (Composite Imaging) button. The level adjustment is intuitive: setting it to 0 deactivates the composite imaging function.
A "one-click" automatic adjustment of 2D/spectral parameters based on real-time ultrasound signals from the examined tissue, instantly optimizing B-mode/spectral Doppler imaging. This reduces operator steps and enhances workflow efficiency.
Enhances B-mode imaging by utilizing tissue-generated second harmonic signals. Harmonic signals, with higher frequency and superior directionality, suppress near-field artifacts and side-lobe interference, improving resolution and contrast—especially in deep tissue imaging—for clearer visualization of fine structures and lesions.
