Abstract: A diagnostic device for acquiring a twelve-lead electrocardiogram of a patient is provided. The diagnostic device has a first glove, or right glove, and a second glove, or left glove, configured to be worn in the hands of a user and intended, in use, to be placed at a portion of a patient's chest to acquire an electrocardiogram of the patient. The first glove, or right glove, and the second glove, or left glove, have a plurality of electrodes configured to detect at least three cardiac signals, corresponding to three cardiac leads. The diagnostic device also includes an electronic unit configured to receive and process said at least three cardiac signals to obtain a 12-lead electrocardiogram.

Abstract: The invention concerns an improved magnetic resonance apparatus and method for substantially reducing the dead time of the apparatus, in order to recover as much of the submicrosecond FID signals as quickly as possible. A double-channel, out-of-phase signal combination is employed. Two RF receiving coils are arranged with identical ringing characteristics, preferably mutually perpendicular to one another. The RF signal received by one coil is phase shifted by 180.degree., amplified, and combined with the amplified RF signal received by the other coil. The ringing components cancel, while the FID components in phase quadrature do not. The transmitter/receiver apparatus may be of duplex or crossed coil configuration. In the latter case, one of the receiver coils may be orientated parallel to the main field so that it receives no FID signal and operates only to reduce the dead time.
