Investigating tumor perfusion by hyperpolarized (13) C MRI with comparison to standard gadolinium contrast-Increased MRI and pathology in orthotopic human GBM xenografts.
In this article you could submit issues and opinions. So far as they get accepted because of the author, they're going to show up above this paragraph together with the writer’s response. The creator will decide on acceptance dependant on certain criteria. Fundamentally, The difficulty must be of sufficiently wide desire.
A not-for-revenue Corporation, IEEE is the earth's premier specialized professional Business focused on advancing technologies for the benefit of humanity.
Concurrently, a shorter laser wavelength could be received; it is possible to operate by using a quantum defect well under one%. As a consequence, the heat generation can be so small this partly compensates the decrease thermal conductivity.
If This is certainly The 1st time you utilized this feature, you may be requested to authorise Cambridge Main to attach using your Dropbox account. Determine more details on conserving articles to Dropbox.
Amplified pulses with the energy earlier mentioned 2.five mJ can be envisioned by applying a greater pump electrical power on the regenerative amplifier and rendering it do the job with the saturation level. The laser fluence of ~1 J/cm2 around the dichroic mirrors is believed KGW Crystal for being under the injury threshold of substantial-quality dielectric-coated mirrors.
Skip to primary content Thanks for checking out nature.com. You will be employing a browser Model with constrained support for CSS. To acquire the very best encounter, we recommend you employ a more up to date browser (or convert off compatibility method in Online Explorer).
The mixed achieve is complex and should be measured under unique pumping disorders as a result of quasi-a few-level program actions of your Yb-doped achieve medium. The blueshift, with a single peak from 1037 nm underneath the similar crystal placement orientation to 1035 nm under the orthogonal crystal placement orientation, could final result in the reabsorption losses at a long wavelength during the crystal exactly where the laser polarization is parallel to its Nm -axis, earning the get at 1035 nm increased than that at 1037 nm below orthogonal orientation.
]. This technique was according to The truth that the spectral emission cross-area curves differ from each other when laser polarization is paralleled to the different optical axis of Yb-doped double tungstates[
In the meantime, to be certain continued aid, we're exhibiting the positioning without the need of types and JavaScript.
