Emulsion diagnostic imaging

The fact that most vegetable oils and fats are nontoxic allows them to be used as reliable excipients or carriers in many pharmaceutical formulations. Vegetable oils and fats have been approved as excipients to facilitate delivery of bioactive compounds, to act as fillers, binders, lubricants, solubilizers, emulsifiers, and emollients in a variety of delivery forms including tablets, capsules, suppositories, emulsions (enteral/parenteral), ointments, creams, and lotions. Other nondirect applications include artificial blood, gene delivery, diagnostic imaging, and medical devices (27). 

Image on the entrance slit. With the aid of one lens this is also possible. Here the structure of the source appears on the entrance collimator and on the detector. This allows spatially-resolved line intensity measurements to be made when a detector with two-dimenional resolution such as a photographic emulsion or an array detector (see Section 2.2.2) are employed. This type of imaging is often used for diagnostic studies.
