Proton transverse relaxation rate of 17O-enriched water.

Proton transverse relaxation rates of 17O-enriched water at pH in the neutral range were determined with isotopic compositions of 17O varying from natural abundance to 5%. Meiboom's account of the proton T-1(2) caused by the scalar interaction between the proton and 17O is generalized to accommodate new data. The generalized formulation covers 17O enrichment above the limit to which Meiboom and his co-worker constrained all their work.

The dynamic spatial reconstructor: a computed tomography system for high-speed simultaneous scanning of multiple cross sections of the heart.

A new generation whole-body computed tomography system has been developed to provide accurate visualization and measurement of the vital functions of the heart, lungs, and circulation. This dynamic spatial reconstructor system (DSR) provides stop-action (.01-sec), rapidly sequential (60-per-second), synchronous volume (240 simultaneous adjacent 1-mm-thick transaxial sections) reconstructions and display of the full anatomic extents of the internal and external surfaces of the heart throughout successive cardiac cycles, and will permit visualization of the three-dimensional vascular anatomy and circulatory functions in all regions of the body of patients with cardiovascular and other circulatory disabilities.
