SonoView After the experiment is complete, the task of examining and manipulating the acquired data must be performed. Although each experimental protocol may be different, making it difficult to standardize any processing algorithms, the Sonometrics post-processing software (SonoView) makes some of the required tasks easier. SonoView allows viewing of each individual sonomicrometer and A/D (analog) trace in a user-friendly, mouse driven environment. Since each data file contains the operating parameters that were in use when the data was saved (the date, time, sampling frequency, etc.), SonoView can list this information, as well as the calibration values for each A/D channel, etc. Some of the features of SonoView include: · filtering and smoothing - eliminates any discontinuities in the acquired distance and analog data which might result from spurious noise or from other experimental equipment; data manipulation - including the derivative of any channel, the average value-per-beat, and the maximum/minimum value-per-beat What remains in terms of data manipulation can be as diverse as the experiments themselves. Therefore, the acquired data sets are saved in a well organized, multi-column ASCII (text) format, making it easy to import into commercially available spreadsheet programs or any of Sonometrics’ custom software packages. CardioSoft CardioSOFT is a dedicated cardiac data analysis package. It has been designed to process acquired data from peripheral devices as well as traditional sonomicrometry distances. Highlights include: A Windows based graphical user interface that allows the user to analyze cardiac functions through a few simple mouse clicks Easy configuration for repeated analysis A large variety of input signals and output calculations that satisfy both experimental and clinical requirements Sample peripheral input signals may be: Cardiac pacing signals Electrocardiogram (ECG)signals Left/Right ventricular pressures Left/Right atrial pressures Arterial pressures Airway pressure Gut lumen pressure Blood flow (aortic, coronary circulation, pulmonary circulation, etc. Aside from the traditional sonomicrometry distances (apical-basal, septal-free wall, anteroposterior, segment length, wall thickness), CardioSOFT can also output volume data by using one of many models of volume calculation. Furthermore, simple calculations of all input signals and their derivatives can be calculated (min/max values,mean values, end systolic and end diastolic values). Finally, complex calculations like heart rate, respiratory rate, stroke work, stroke volume, cardiac output, and ejection fraction can also be calculated.

If a sufficient number of crystals are used, and placed strategically, our 3-D software can convert the matrix of distance measurements into the appropriate x,y,z coordinates for each crystal. Data in this format can be used to reconstruct the 3-dimensional image of any structure and show how this is changing over time. Our 3-dimensional analysis software uses a triangulation algorithm to convert distance measurements into x,y,z coordinates. Typically, one transducer is taken as the origin of the coordinate system, another defines the x-axis, a third helps to define the x-y plane, and a fourth is used to set the positive z direction. An array of 16 crystals, for example, can yield 240 unique distances, which are more than enough combinations to calculate a unique set of x,y,z coordinates for each crystal. This is referred to as an "over determined system" and is solved using an iterative approach. Continuous iterations minimize the total sum of the differences between original and reconstructed distances (for all pairs of crystals). Our 3-D viewing program can then be used to see the entire crystal array moving in time and 3-dimensional space. Click here to download the demo program [link to demo downloads page]
