BACKGROUND
This invention relates to a medical diagnostic ultrasound system and method. Ultrasound systems generate a sequence of images representing a region of a body. Different processes and hardware are used to generate the images. Many of the processes and hardware components are divided into ultrasound subsystems. Each subsystem is typically implemented with an ASIC. The ASIC is designed to perform a particular process. The processes are determined in part as a function of the system architecture or ASIC based design.
The subsystems are connected to a back plane or common structure to form the ultrasound system. The ultrasound system typically is mounted on a large wheeled cart.
BRIEF SUMMARY
The present invention is defined by the following claims, and nothing in this section should be taken as a limitation on those claims. By way of introduction, the preferred embodiment described below includes a method and system for providing temporally accurate EKG data with imaging is provided. The EKG data is linked to imaging data. The frame of data of imaging data contains EKG data in a line of information. Additional EKG data may be provided separately from the imaging data. A scan converter processes both the EKG data and imaging data at substantially the same time, maintaining temporal accuracy. The EKG data provided comprises an entire trace so that the trace on the display appears to be smoothly updated.
Further aspects and advantages of the invention are discussed below in conjunction with the preferred embodiments.
