Abstract: Various methods and systems are provided for conveying information about cleaning, disinfection, and sterilization (e.g., processing) of touchable components of a medical device using visually detectable indicators (VDIs). Information regarding processing of an ultrasound device may be conveyed by configuring the ultrasound device to include a first component with a first visual indicator to indicate a first processing level and a second component with a second visual indicator to indicate a second processing level. Implementing visual indicators to convey information about processing may reduce time, cost, and other resources used to process medical devices compared to conventional processing methods wherein the entire medical device may be processed to one processing level.

Abstract: An automated measurement system for an ultrasound and/or echocardiographic imaging system enhances reproducibility of measurement results and accommodates form movement in the measurement of the images by combining measurements across multiple cardiac cycles/multiple echocardiogram images. The automated system provides these benefits by initially selecting the cardiac images/cycles for which valid measurements can be obtained within constraints defined by the automated system. With these selected cycles, the automated system then combines the measurements from the selected cycles into a global measurement for the desired parameter or parameters for the combined cycles.

In one embodiment, a method comprises calculating transparency values for a plurality of voxels based on a variance value and a velocity value of each voxel and a time corresponding to acquisition of each voxel, and rendering an image with the calculated transparency values applied to the plurality of voxels. In this way, the visualization of turbulent blood flow can be tailored to the dynamics of the blood flow, thereby enabling an improved diagnostic accuracy.

Abstract: An ultrasound system and method for calculation and display of tissue deformation parameters are disclosed. The tissue deformation parameter strain is also determined by an accumulation of strain rate estimates for consecutive frames over an interval. The interval may be a triggered interval generated by, for example, an R-wave in an ECG trace. The strain calculation may be improved by moving the sample volume from which the strain rate is accumulated from frame-to-frame according to the relative displacement of the tissue within the original sample volume. The relative displacement of the tissue is determined by the instantaneous tissue velocity of the sample volume.

Abstract: System and method for automatically measuring the delay of tissue motion and deformation. For example, asynchrony may be measured between the left and right ventricles and within the left ventricle. A measurement feature may be defined by default or obtained using a user input. A reference time and a search interval are identified. The search interval may be based on the reference time, or input or modified by a user. A time delay of the measurement feature within the search interval is calculated for each sample. At least one color is assigned to the samples corresponding to the calculated time delay.

A cardiac resynchronization therapy (CRT) lead placement planning module compares at least a portion of the patient study data for each of the segments. An output device indicates at least one location for placement of an LV lead within one of the segments of the patient's LV during a CRT procedure based on the comparison of the at least a portion of the patient study data for each of the segments.
