In a diffusion tensor magnetic resonance imaging method for imaging a myocardial fiber structure, the diaphragm position of a subject is detected and a determination is made as to whether the diaphragm position of the subject falls into the acceptance region or not. If it does not, continue the diaphragm position of the examination subject is continued to be detected.

Resuscitation enhancements
A system including a sensor interface coupled to a processor. The sensor interface is configured to receive and process an analog electrocardiogram signal of a subject and provide a digitized electrocardiogram signal sampled over a first time period and a second time period that is subsequent to the first time period.

Ultrasound diagnosis method and apparatus using electrocardiogram
An ultrasound diagnosis method using an electrocardiogram (ecg) including: obtaining ecg information; generating first volume data using at least one piece of sub volume data obtained in a first ecg cycle based on the ecg information; generating second volume data using at least one piece of sub volume data obtained in a second ecg cycle based on the ecg information; and displaying at least one of the first volume data and the second volume data.. .

Generative model-driven resource-efficient monitoring in body sensor networks
Body sensor networks (bsns) and methods for monitoring an electrocardiogram using such bsns include a base station that generates an ecg model and an output ecg signal for displaying on a display device, and a sensor platform in electrical communication with the base station. The sensor platform may be configured to receive a sensed ecg signal from one or more sensors, receive an instance of the ecg model, and produce a model ecg signal from the instance.

Electrocardiogram reconstruction from implanted device electrograms
A method of reconstruction of the standard 12-lead surface ekg given values of the electrical potential from an implanted medical device is described. This implanted device can be oriented in an arbitrary fashion and reconstruction technique is obtained through physical measurement of the orientation of the implanted device or correlation with a standard 12-lead ekg obtained from the patient..
