The evaluation of the ventricular function has a key role in determining therapy and prognosis in patients with heart disease. The standard analysis is limited to quantification of tele-diastolic and tele-systolic frames. An analysis of wall kinetic in each frame of cardiac cycle might allow further information about contractility and diastolic function. The developed algorithms are aimed to achieve an automatic detection of left ventricular wall kinetic during a cardiac cycle in routine clinical activity.

The routinely used clinical practice of manual tracing of the blood pool from short axis cine MR images to compute ejection fraction (EF) is cumbersome, time consuming, and operator dependent. In this paper we present an algorithm that automatically segments the left ventricle (LV) using the a priori knowledge of the intensity responses of the tissue in different MR modalities, along with the LV morphology. Our method for the automatic computation of the EF is based on segmenting the left ventricle by combining the fuzzy connectedness and the physics-based deformable model frameworks. We have validated our method against manual delineation performed by experienced radiologists on the data from nine asymptomatic volunteers with very encouraging results.

Recent advances in Magnetic Resonance Imaging allow fast recording of contrast enhanced myocardial perfusion scans. MR perfusion scans are made by recording, during a period of 20-40 seconds a number of short-axis slices through the myocardium. For perfusion analysis, the myocardial boundaries must be traced, dividing the heart into the left and right ventricle blood volumes and the myocardium of the left ventricle. Extreme care must be taken not to include any part of the left or right ventricle blood volumes in the myocardium segment, because this has a significant effect on the perfusion analysis. On the other hand, for accurate estimation of the perfusion parameters, all available myocardium area in the image is required. In this paper a method is proposed to correct for any inclusion of left and right ventricle and optimally place the myocardial contours.

Carotid vessel ultrasound imaging is a reliable noninvasive technique to measure the arterial morphology. Lumen Diameter (LD), intima-media thickness (IMT) of the far wall, and plaque presence can be reliably determined using B-mode ultrasound. In order to measure the carotid IMT as well as any other more complex quantitative indices of vessel morphology, it is necessary to identify lumen-intima and media-adventitia borders in the ultrasound images. In this paper we describe an automatic approach to measure LD and IMT based on an active contour technique improved by a multiresolution analysis. The measurements of LD and IMT were compared to manual tracing of the vessels border in terms of coefficients of variability (CV) and correlation (R). The results have shown that the method is a reliable and reproducible way of assessing the LD and far wall IMT in the carotid artery.

Numerical modelling of the coronary tree is well established. Solutions of the Navier-Stokes equations can produce wall shear stress distributions which can be used to correlate the position of shear stress distribution with coronary artery disease. We have previously demonstrated a technique for reconstructing a single branch of the coronary tree. The introduction of junctions into the model allows for accurate reconstruction of potentially the entire arterial tree. However the introduction of a realistic junction has proven to be difficult. A four section method for branching has been adopted, utilising three tubular segments and a small junction section as the join. This allows for automatic generation of the majority of the artery (the tubes), and a semi-automated procedure concentrating specifically on the junction. A structured mesh is used for the tubes, allowing for easy generation and improved computation time, whilst an unstructured mesh is used to accurately model the irregular shape of the junction. The four section method allows for easy insertion of more branches, depending on the level of detail required. Another advantage is that as time evolves, inducing conformational changes throughout the cardiac cycle, the tubes can be regenerated, whilst the junction needs only slight modification. Marked changes are induced in wall shear stress by either adding extra junctions to an arterial tree, or altering the shape of major branches.

In this newly developed software, the anatomical variation of the three-dimensional coronary vessel system can be recreated. A few mouse clicks are sufficient to reproduce an anatomically correct model of the patients own coronary artery system with respect to vessel size and number. The localization, the severity and type of stenosis can be entered, as well as grafts and stents. Through the use of anatomically accurate visual representations of coronary anatomy, the transfer of complex coronary angiography information between operators, cardiologists, and surgeons is enhanced and expedited.

Depth and radius of the region interrogated by cardiac optical mapping with a laser beam depend on photon travel inside the heart. It would be useful to limit range of depth and radius interrogated. Here the effects of a condensing lens to concentrate laser light at a target depth in the heart was modeled Monte Carlo computer simulations that incorporated a 0.55 NA lens in air and absorption and scattering of 488 nm laser light in 3-d cardiac tissue indicated the distribution of excitation light fluence. A subsequent computer simulation incorporating absorption and scattering of transmembrane voltage-sensitive fluorescence (669 nm) indicated locations in tissue from which fluorescence photons exiting the tissue surface originated The results indicate the heart can be interrogated at a discrete depth below the surface of myocardium with a condensing lens, although resolution is limited This may be applicable to laser scanner systems used for cardiac optical mapping.

Using the Long-Term ST Database, we developed and evaluated an advanced algorithm for automated detection of transient ST segment episodes in "real-world" 24-hour ambulatory data. To successfully detect transient ST change episodes, the algorithm automatically tracks the time-varying ST segment reference level due to clinically not important non-ischemic causes and subtracts it from the ST segment level. Evaluating of the algorithm using reference annotations of the protocol B of the database yielded gross ST episode detection sensitivity and positive predictivity of approximately 75%.

In stress test ECG analysis, the so-called ST/HR hysteresis has recently been suggested to improve coronary artery disease (CAD) diagnosis. This parameter is estimated from the ST versus HR diagram including exercise and recovery phases. Unluckily, ST measurements are adversely affected by noise during the test. In this study we propose a method to automatically estimate the ST/HR hysteresis, incorporating multiple stage noise attenuation. The method is based on averaging and rejection of noisy beats. Evaluation is done on simulated exercise test recordings, constructed from real ECG averaged beats adding actual noise from stress test records. Results on a total of 216 different records, with RMS noise levels ranging from 114 to 979 /spl mu/V, give a reduction in estimation error in the ST/HR diagram of 77.98% (from 168 to 37 /spl mu/V) in mean and of 76.38% (from 271 to 63 /spl mu/V) in standard deviation. This method may be considered as a suitable and robust tool for reliable ST/HR hysteresis estimation.

A dedicated cardiology information system (CARIS) has been developed in our department to record all information pertaining to studies performed in the cathlab and pacemaker lab. However, information stored in other systems in the cardiac function lab was not available in CARIS. This includes ECGs (rest ECGs, stress ECGs and Holter ECGs), and reports from echo studies and stress ECG studies. Data obtained from these functional studies are stored in various database systems. For each of these systems a different, dedicated interface was developed to allow the cardiologist to obtain access to the data from within CARIS. These results show that integration of all information available in the cardiology department is feasible. Presently, we are developing a completely new version of CARIS that will allow optimal integration of cardiology based information (as well as in the CARIS database, as in separate systems) with data in the hospital information system.
