An approach to noninvasively, remotely and accurately detect core body temperature in a warm-blooded subject, human or animal, via thermal imaging. Preferred features such as the use of in-frame temperature references, specific anatomical target regions and a physiological heat transfer model help the present invention to overcome pitfalls inherent with existing thermal imaging techniques applied to physiological screening applications. This invention provides the ability to noninvasively, remotely and rapidly screen for diseases or conditions that are characterized by changes in core body temperature. One human application of this invention is the remote screening for severe acute respiratory syndrome (SARS), since fever is a common, early symptom. Other diseases and conditions that affect the core body temperature of humans or animals may also be noninvasively and remotely detected with this invention.

Described here are a system and method for designing radio frequency ("RF") pulses for parallel transmission ("pTx") applications, and particularly pTx applications in multislice magnetic resonance imaging ("MRI"). The concept of "SAR hopping" is implemented by framing the concept between slice-selective excitations as a constrained optimization problem that attempts designing multiple pulses simultaneously subject to an overall local SAR constraint. This results in the set of RF waveforms that yield the best excitation profiles for all pulses while ensuring that the local SAR of the average of all pulses is below the regulatory limit imposed by the FDA. Pulses are designed simultaneously while constraining local SAR, global SAR, and peak power, and average power explicitly.

In a method and apparatus for magnetic resonance imaging with adherence to SAR limit values, a patient is subjected to a radio-frequency pulse sequence via at least one transmission antenna and the magnetic resonance signals that are produced are acquired in a spatially resolved manner via at least one reception antenna and are further-processed for producing magnetic resonance images or spectra, with current SAR values, determined before the implementation of the measurement on the basis of patient data and the position of the patient relative to the transmission antenna for planned parameters of the measurement, being modified as warranted until the current SAR values lie within the SAR limit values. The determination of the current SAR values ensues by comparing the current measurement situation to pre-defined measurement situations stored in a data bank for which pre-calculated SAR values are stored. The stored SAR value of the measurement situation of the data bank coming closest to the current measurement situation is utilized as the current SAR value. A reduction of the calculating outlay for determining the SAR values during the examination is achieved, and the data bank values can be calculated highly detailed, allowing a more exact determination of the current SAR values. The reduction of the safety margins that is achieved allows an enhancement of the system performance for the user, so that the user can implement the measurements in a shorter time and/or simultaneously acquire a number of tomograms.

A method of exciting nuclear spins in a sample, wherein a plurality of transmit coils are driven in parallel to emit respective radio-frequency excitation pulses, the method comprising computing the phases and/or amplitudes of said excitation pulses by solving an optimization problem for minimizing the difference between the excitation distribution within said sample and a target excitation distribution, and being characterized in that: said optimization problem includes a cost function depending on the power emitted by said transmit coils through respective coil-dependent weighting coefficients; and in that the phases and/or amplitudes of the excitation pulses are computed iteratively, each iteration step comprising: solving said optimization problem based on present values of the weighting coefficient, and subsequently updating the value of at least one of said coefficients so as to control in a predetermined way the local specific absorption rate—SAR—distribution within the sample. The method of the invention allows, in particular, reducing the local SAR maximum value within the sample and/or ensuring that the local SAR takes its maximum value within a predetermined region of the sample.

In a method for magnetic resonance imaging with adherence to SAR limit values, a patient is charged with a radio-frequency pulse sequence via at least one transmission antenna for the implementation of a measurement in a magnetic resonance tomography apparatus, and the magnetic resonance signals that are produced are acquired in a spatially resolved manner via at least one reception antenna and are further-processed for producing magnetic resonance images or spectra. SAR values are determined before the implementation of the measurement on the basis of patient data and the position of the patient relative to the transmission antenna for planned parameters of the measurement, and the parameters are modified as needed until the SAR values lie within the SAR limit values. The position of the patient relative to the transmission antenna is exactly determined by an imaging magnetic resonance pre-measurement. The method enables adherence to the SAR limit values without having to take large tolerances into consideration. No additional hardware whatsoever and no positioning rule for the user are required for the realization of the method.
