Echocardiography

View this topic in
An echocardiogram, often referred to in the medical community as a cardiac ECHO or simply an ECHO, is a sonogram of the heart (it is not abbreviated as ECG, which in medicine usually refers to an electrocardiogram). Also known as a cardiac ultrasound, it uses standard ultrasound techniques to image two-dimensional slices of the heart. (Wikipedia.org)

High frame rate ultrasonic imaging of the heart by placing virtual point sources in front of array

2013 IEEE International Ultrasonics Symposium (IUS), 2013

We previously developed a method for high frame rate echocardiography [frame rate (FR) > 300 Hz] using a transmit beam, which was spherically diverging from a virtual point source behind the array. Although such diverging beam illuminates a wider area compared with a focused beam or plane wave, sound pressure starts to decrease just after emission. Another type of a ...

High-frame-rate ultrasound imaging using diverging waves has demonstrated its potential as a useful cardiac imaging method. It has been shown that the compounding of steered beams improves static images quality. In the presence of high-velocity tissue motion, however, the combination of successive steered diverging waves is incoherent and thus deteriorates the image contrast. Motion compensation (MoCo) integrated in the coherent ...


In vivo guided numerical modeling of pulmonary venous waveforms: a paradigm for applied physiology research

Computers in Cardiology 1999. Vol.26 (Cat. No.99CH37004), 1999

The determination of pulmonary venous velocities from pulsed Doppler echocardiography is valuable for the assessment of left ventricular diastolic dysfunction, yet little is known regarding the relationship between actual pressure gradients and measured velocities. Combining results of in vivo experiments and numerical modeling, a linear relationship was observed between actual pulmonary venous-left atrial pressure gradients and measured velocities (convective forces) ...

  • High frame rate ultrasonic imaging of the heart by placing virtual point sources in front of array

    We previously developed a method for high frame rate echocardiography [frame rate (FR) > 300 Hz] using a transmit beam, which was spherically diverging from a virtual point source behind the array. Although such diverging beam illuminates a wider area compared with a focused beam or plane wave, sound pressure starts to decrease just after emission. Another type of a diverging beam, which is diverging from a focal point of a conventional focused beam, has already been proposed for synthetic aperture imaging. This type of beam can increase sound pressure around the focal point, and it would be useful for applications which require higher sound pressure, such as blood flow imaging. In the present study, the feasibility of high frame rate echocardiography using diverging beams from conventional focused beams was examined. In the present study, multiple focused receiving beams were created using diverging beams in front of focal points of conventional focused transmit beams. Smaller focal distance achieves a wider diverging angle and the number of transmissions can be reduced. In the proposed method, wave fronts were assumed to be spherical, and dynamic focusing was used in receive. Since multiple receiving beams were created for each transmission, overlapping receiving beams were averaged after beamforming. The proposed method was evaluated using an ultrasound imaging phantom. Spatial resolutions (width at half maximum) of parallel beamforming with plane wave and diverging beams from virtual point sources at distances of 100 mm behind array and 20 mm in front of array were 1.17, 1.04, and 1.08 mm (at 44 mm depth), respectively. B-mode images could be obtained with good spatial resolutions using transmit beams diverging in front of focal points.

  • Automatic bubble detection with neural networks on post decompression frames

    Post decompression records in echocardiography are considered to detect micro bubbles and to survey unexplained decompression sickness which is commonly examined by standardized methods such as dive computers and tables. In this study, existent bubbles are detected on transthoracic echicardiografic frames recorded after recreational diving. Bubble detection is performed by Artificial Neural Networks which are trained using bubbles with different morphologies. We showed that bubbles would be detected on four cardiac chambers without image segmentation.

  • Development of recognition software of heart to find the standard cross section on echocardiography

    We have developed an algorithm to find standard cross sections (the long-axis view and the short-axis view) of the heart from successive echograms. We first divided an echogram into small spatial regions and detected the typical motion of the mitral valve by analyzing the brightness variation and correlation coefficient among the regions. We have obtained 95% accuracy in the position of the valve through time series echogram of 25 normal volunteers. The recognized valve was visualized as a mark on the video stream. Furthermore, combining this technique with an optical flow method, we elucidated the region velocity of the wall motion of the left ventricle after centering the valve on echogram. By analyzing symmetry among region velocity, we have confirmed to distinguish between the long- and the short-axis view of heart. This algorithm is applicable to instruction software to find standard cross section of the heart as an assistant of echocardiography. We are going to apply to more subjects who have heart disease and to contribute automatic diagnosis in the future.

  • High-frame-rate velocity vector imaging echocardiography: an in vitro evaluation

    High-frame-rate ultrasound imaging using diverging waves has demonstrated its potential as a useful cardiac imaging method. It has been shown that the compounding of steered beams improves static images quality. In the presence of high-velocity tissue motion, however, the combination of successive steered diverging waves is incoherent and thus deteriorates the image contrast. Motion compensation (MoCo) integrated in the coherent compounding process has recently shown to be a very promising technique to provide high-contrast B-mode images of the cardiac muscle. Ultrafast cardiac motion estimation based on speckle tracking could greatly benefit from this original method. In this study, Velocity Vector Imaging (VVI) was applied on high-frame-rate envelope images performed with MoCo to estimate the myocardium 2-D motion. The method was investigated in vitro, using a rotating disk. With sequences of steered diverging waves (pulse repetition frequency = 4500 Hz) generated by the full aperture of a 2.5 MHz phased array, high-contrast high-resolution images were constructed at 500 FPS using MoCo. Standard cross-correlation and phase correlation in the Fourier domain were applied to generate VVI on the pre- scanned envelope images at 100 images/s. The estimated in vitro velocity vectors were consistent with the expected values, with an average normalized error of 6.0% +/-0.4% in the radial direction, and 13.1% +/-1.2% in the cross- range direction. These results make us confident to pursue the study with in vivo investigations.

  • In vivo guided numerical modeling of pulmonary venous waveforms: a paradigm for applied physiology research

    The determination of pulmonary venous velocities from pulsed Doppler echocardiography is valuable for the assessment of left ventricular diastolic dysfunction, yet little is known regarding the relationship between actual pressure gradients and measured velocities. Combining results of in vivo experiments and numerical modeling, a linear relationship was observed between actual pulmonary venous-left atrial pressure gradients and measured velocities (convective forces) measured using pulsed Doppler echocardiography. Strong model correlations were observed for the systolic (y=0.20x-0.13, r=0.97) and diastolic (y=0.25x-0.34, r=0.99) phases of the pulmonary venous waveform. In vivo results were similar for the systolic (y=0.234x+0.01x, r=0.82) and diastolic (y=0.22x+0.09, r=0.81) phases. Modeling, combined with in vivo experiments can complement each other in understanding complex physiology.

  • 3D echocardiography data processing for wall motion estimation

    A method for the estimation of motion of ventricular structures based on 3D echo data processing is presented. The Lucas-Kanade algorithm has been utilized and implemented in a multi-step version. The algorithm is based on the recognition of characteristic points (feature points) within the volume and to track them during motion. The extrapolation of the motion field to the entire volume has been performed by interpolating the estimated velocity vectors corresponding to the feature points by using a model for diffusion and regularization of the field. Results have been obtained on synthesized data and in vivo 3D echo data.

  • Right ventricular wall mechanics in normals and patients with pulmonary hypertension using magnetic resonance tissue tagging

    Right ventricular hypertrophy (RVH) and RV dysfunction are difficult to evaluate due to the complex shape of the RV and prognostic limitations of conventional global function parameters. We used MRI with magnetization tagging to measure 2-D systolic motion and deformation of the right ventricular free wall (RVFW) and septum (SEPT) in 5 patients with RVH secondary to pulmonary hypertension, and 12 normal volunteers (NL). Regional displacement (D) and 2-D principal strains in the short-axis plane were averaged at basal, midventricular and apical levels. SEPT D was severely decreased at all levels in RVH vs. NL (P<0.005). In RVH, RVFW D was higher than SEPT D (P<0.02). The 2-D strains were reduced in SEPT at all levels in RVH vs. NL (P<0.05). This technique may permit the study of progression and regression of RVH in various disease states.

  • A Workstation for the Quantitative Analysis of Real-Time Myocardial Contrast Echocardiography

    The real-time myocardial contrast echocardiography (RT MCE) is a new echocardiography technology, which allows clinicians to evaluate the perfusion of myocardial capillary of patients, noninvasively and accurately. We designed a workstation for the quantitative analysis of RT MCE. The system was capable of estimating some hemodynamic parameters of myocardial micro-circulation, and computing time-intensity curves to indicate the variation of the intensity of microbubbles scatting for various myocardial segments in subendocardial and subepicardial. The system also conformed to the digital imaging and communications in medicine (DICOM) standard and could be integrated into the picture archiving and communication system (PACS). The examples of clinical study indicated the clinical effectiveness of the system and the reliability of the quantitative analysis techniques employed in the system.

  • A unified approach for clinical decision making

    A methodology based on rough sets has been developed to aid physicians in determining the most likely diagnostic hypothesis to account for a set of patient findings. The domain of valvular heart disease is used to test solution methods that should be applicable to other medical areas. A key design philosophy underlying rough sets is that the physician should have control of the computer interaction to determine what is to be done (clinical examinations) and what the necessary decisions to be taken are, using only the available incomplete and imprecise information.<<ETX>>

  • Remote digital echocardiography for the identification of cardiac valvular disease

    The Pacific Island Health Care Project cares for 250-500 patients from the US- associated Pacific Islands. Unique to the Pacific Basin is a high incidence of acute rheumatic fever, a condition that not uncommonly results in valvular heart disease. Identification of patients with severe valvular heart disease may qualify them for care in the military medical system under this project. Echocardiography has become an essential diagnostic tool for the cardiologist in identifying heart valve problems. Brooke Army Medical Center (BAMC) has established a digital echocardiography network to serve the Great Plains Region. Currently, echocardiograms are digitized at remote sites, transferred to BAMC for evaluation and stored in DICOM standard format on optical disk. The digital network system provides improved care for patients, reduces patient transport costs, permits local follow-up and reduces health care costs. New digital technologies currently under evaluation at our institution will provide smaller, less costly, portable digital imaging systems and make digital echocardiography imaging networks feasible for remote health care facilities. Combining this technology with the new era of digital imaging will allow portable echoes to be used as an extension of the stethoscope. Evaluating heart function and valvular disease in a local health facility will decrease the need for transportation of the patient to a larger facility for diagnosis or follow-up evaluation.
