Embodiment Construction

[0012] All other things being equal, the temperature rise (ΔT) of the ultrasound probe is directly proportional to the frame rate of the image. Thermal management in ultrasound probes can therefore be achieved by switching the image capture frame rate between two modes: a first mode with a high frame rate, used when the imaging task at hand requires a high frame rate, and a low frame rate The second mode of , used when high frame rates are not required. Optionally, a third mode with a lower frame rate (or zero frame rate) can be used to allow the detector to cool down more quickly after operating in the first mode.

[0013] For TEE imaging of the heart, a frame rate of 50 frames per second (fps) is appropriate, as this frame rate is fast enough for high speed applications (e.g., visualization of parts of the heart that contract late in cardiac resynchronization therapy applications) , the re-randomization is slow enough for "speckle" noise from blood (thereby reducing the imp...

Abstract

To keep the temperature of an ultrasound probe down, the probe is operated at a low frame rate (with correspondingly low heat generation) for the vast majority of time. Probe operation is only switched to the high frame rate temporarily at times when high temporal resolution is needed, preferably under operator control. The probe is only operated at the high frame rate for a short period of time, during which a burst of images with high temporal resolution is obtained. After capturing the short burst of images, the frame rate is cut back, which reduces the generation of heat.

Description

[0001] Cross reference to related applications [0002] This application requires the priority of the US temporary application 60 / 941,480 submitted on June 1, 2007. Background technique [0003] A conventional method of monitoring cardiac function is through the esophageal ultrasound heart dynamic diagram (Tee). In this method, the detector containing an ultrasonic converter is inserted to the esophagus and located so that the converter can be near the patient's heart.Then use the detector to capture the heart video image in real time, which are usually displayed on the video monitor.Conventional Tee detectors are usually between 10-15mm (for adults).Due to this large diameter, conventional Tee often requires anesthesia to seriously threaten the trachea, which is not suitable for long -term surveillance of the heart.Recently, a smaller Tee detector that can be monitored and eliminated for a long time can be monitored and eliminated or reduced the need for anesthesia, such as US2005...
