Systems and methods of utilizing communications networks and multivariate analysis to predict or recommend optimal products from a predefined population of commercially available products are disclosed. The recommendations are based on intelligence contained in processing elements and subjective and/or objective product information received from consumers or input to the systems as part of their initial setup. The output of the systems comprise sets of products that they predict the consumer will prefer and/or perform well for the problem or concern identified by the consumer. The performance and preference predictions are a function of consumer problems and product responsiveness patterns. Objective product information is generally obtained with diagnostic instruments.

A real-time biological data processing PC card is lightweight, cost effective, and portable. The real-time biological data processing PC card is capable of converting a host personal computer system into a powerful diagnostic instrument. Each real-time biological data processing PC card is adapted to input and process biological data from one or more biological data sensors, and is interchangeable with other real-time biological data processing PC cards. A practitioner having three different real-time biological data processing PC cards, for example, each one corresponding to a different biological data collection device, effectively carries three full-sized, powerful diagnostic instruments. The full resources of a host personal computer can be utilized and converted into a powerful diagnostic instrument, for each biological data collection device, by the insertion of one of the real-time biological data processing PC cards.

The present invention further relates to the selection of the specific filter combinations, which can provide sufficient information for multivariate calibration to extract accurate analyte concentrations in complex biological systems. The present invention also describes wavelength interval selection methods that give rise to the miniaturized designs. Finally, this invention presents a plurality of wavelength selection methods and miniaturized spectroscopic apparatus designs and the necessary tools to map from one domain (wavelength selection) to the other (design parameters). Such selection of informative spectral bands has a broad scope in miniaturizing any clinical diagnostic instruments which employ Raman spectroscopy in particular and other spectroscopic techniques in general.

A downloadable agent facilitates medical image transmission in accordance with a clinical trial protocol. The agent includes program code for obtaining or receiving a medical image from a computer storage device or a DICOM-compliant diagnostic instrument, program code for accepting textual information about the patient or medical image and associating the textual information with the medical image to prevent dissociation of the textual information and the medical image, program code for executing a data compliance protocol, program code for encrypting the image and textual information and for compressing at least the image, and program code for transmitting the encrypted image and textual information across a wide area network to a remote translator for decompressing, de-encrypting and viewing of the image and textual information. The data compliance process prohibits inclusion of patient identity information in the associated textual information and medical image.

In a tissue tracking imaging (TTI) method, a velocity distribution image from which a translation velocity component or a rotation velocity component resulting from movement of a body, etc. is removed is generated every time phase. By tracking a predetermined position of a tissue on the basis of the velocity distribution image and generating a motion information image, it is possible to provide a diagnostic image having higher reliability.

A system for removing liquid waste from an automated diagnostic instrument. The system comprises

• • (a) an accumulator having at least one inlet for waste liquids and at least one outlet for waste liquids;
  • (b) a vacuum sub-system connected to the accumulator, said vacuum sub-system comprising a vacuum pump; and
