Sims position

Secondary ion mass spectrometry (SIMS) is by far the most sensitive surface technique, but also the most difficult to quantify. When a surface is exposed to a beam of ions (Ar", 0.5-5 keV), energy is deposited in the surface region of the sample by a collisional cascade. Some of the energy will return to the surface and stimulate the ejection (desorption) of atoms, ions, and multi-atomic clusters. In SIMS, positive or negative secondary ions are detected directly with a quadrupole mass spectrometer.

Position the patient in the Sims position (left side lying). 

The client should lie on the left side (Sims position). 

In the ToF-SIMS positive ion spectrum the peaks characteristic of LDPE and PEMA appear but as the MA concentration increases some of the hydrocarbon peaks (eg CH3+, C5H9+, C6Hn+, C7H13+), initially with the relative intensities expected from LDPE, increase in intensity and EMA-specific ions, eg, C2H302, are detected (high mass resolution required). Two of these ions, normalized to the nonspecific C2H3+ ion, are plotted as a function of bulk MA content in Figure 23. 

ToF-SIMS positive total ion images as well as the sodium, calcium, and silicon images are reconstructed from the RAW files of the skull and rib obtained in the tissue imaging analysis. 

This chapter describes the application of muscle energy techniques to group curves and single-segment somatic dysfunctions in the lumbar spine. For the described techniques, the patient lies on Ws side on the table or in a modified Sims position. The transverse processes of the segment to be treated are oriented either upwards or downwards, according to the precise technique. 

Patient position Side-lying on the table. The posteriorly rotated transverse process to be treated faces upward. The patient is placed into a modified Sims position (the mnemonic "SUE" to indicate Sims, posterior facets Upward, and Extension dysfunction may be used). 

Patient position Sims position (patient s chest with upper torso prone and hips and knees flexed], with the axis of the dysfunction down toward the table. The patient s arms hang off the sides of the table.
