First Claim
Patent Images
1. A medical diagnostic ultrasound imaging system comprising:
- a received signal path;
a central processing unit coupled with the received signal path; and
a first memory device coupled with the central processing unit;
wherein the central processing unit comprises a non-real-time operating system to transfer image data between the received signal path and the first memory device.

Abstract
The preferred embodiments described herein provide a medical diagnostic ultrasound imaging system and method in which a non-real-time operating system is used to transfer image data. In one preferred embodiment, a medical diagnostic ultrasound imaging system includes a central processing unit (“CPU”) located outside of the received signal path to transfer image data. The non-real-time operating system can be used, for example, to transfer image data from a hard disk to system memory for display, to transfer image data from system memory to the hard disk for storage, or to scroll image data to view a loop of image data.

18. A method for transferring image data in a medical diagnostic imaging system using a non-real-time operating system, the method comprising the acts of:
-
(a) providing a central processing unit in an ultrasound imaging system, the central processing unit comprising a non-real-time operating system; and
(b) with the non-real-time operating system, transferring image data in the ultrasound system;
wherein (b) comprises, with the non-real-time operating system, transferring image data between a received signal path and a first memory device. - View Dependent Claims (19, 20, 21, 22)
(b1) with the non-real-time operating system, transferring image data from the received signal path to the first memory device; and
(b2) with the non-real-time operating system, transferring image data from the first memory device to a second memory device.

-
20. The method of claim 18, wherein (b) comprises:
-
(b1) with the non-real-time operating system, transferring image data from a second memory device to the first memory device; and
(b2) with the non-real-time operating system, transferring image data from the first memory device to the received signal path.

-
21. The method of claim 18 further comprising the act of, with the non-real-time operating system, transferring image data from the first memory device to a second memory device at a faster rate than a rate at which the first memory device will reach capacity.
-
22. The method of claim 18 further comprising the act of, with the non-real-time operating system, preventing further image data from being written to the first memory device in response to the first memory device reaching capacity.
