Linear arrays are designed for use in conventional high-resolution imaging of musculoskeletal or superficial vascular features and can also be used in compound scanning (SonoCT) and Doppler blood velocity determination. Two-dimensional arrays can have up to 2,400 elements and produce full-volume images for cardiology applications. Arrays are attractive because they can be used to focus on an object or organ within the body by varying the transmit and to receive signals (phasing) to the elements.

The location of the two crystals that detect the two anti-parallel g-rays defines a line along which the annihilation occurred. This process is referred to as annihilation coincidence detection (ACD) and forms the basis of signal localization in PET. The spatial distribution, rate of uptake, and rate of washout of a particular radiotracer are all quantities that can be used to distinguish diseased from healthy tissue. , 11 C ¼ 20:4 minutes; 15 O ¼ 2:07 minutes; 13 N ¼ 9:96 minutes; 18 F ¼ 109:7 minutes) and must be synthesized onsite using a cyclotron.

2. ‘‘Negative’’ MR contrast agents are based on small ferromagnetic iron particles, with various types of coating and size distributions. S. Food and Drug Administration that consists of dextran-coated superparamagnetic iron oxide (SPIO) particles with diameters in the range of 80–100 nm. These agents reduce the T2 value of the water protons by causing inhomogeneities in the local magnetic field and therefore producing areas of signal void in T2 -weighted sequences. Since the particles accumulate in healthy regions of the reticuloendothelial system (liver, spleen, lymph node, bone marrow), comparisons of images before and after administration of the agent reveal diseased regions with unchanged signal intensity.
