Volumetric Measurement If the amount of gas exiting a column or split vent is measured in units of volume, the flow rate is volumetric based. For example, measuring the volume of gas in milliliters (mL) per unit time in minutes will result in a volumetric flow rate in mL/min. Usually, flow rates are measured at ambient temperature and pressure.

An automated method and / or system for identifying suspected lesions in a brain is provided. A processor (a) provides a magnetic resonance image (MRI) of a patient's head, including a plurality of slices of the patient's head, which MRI comprises a multispectral data set that can be displayed as an image of varying pixel intensities. The processor (b) identifies a brain area within each slice to provide a plurality of masked images of intracranial tissue.

The present invention is a medical infusion and aspiration system delivering precisely timed and accurately calculated, adjusted pulsated delivery in high rates of flow delivering an effective profile of pulses tailored to provide momentary spikes of levels of freely available medicines based upon the uptake of the medicine and optimally on real time measurements of the medicine or response of the patient, termed Quantitative Chronological Delivery. The system comprises any pumping mechanism, and optimally a pumping mechanism, and a cassette or cartridge having a reservoir area where the plunger rotates as it advances in reference to the cartridge to provide additional accuracy and overcome the forces of inertia and slip-stick as well as eliminate backlash. Optimally, the systems incorporates an encoded area and an opening for connection to an infusion tube with an in-line sensor area where sampling probes are located. The infusion is adjusted in both amount and duration between pulses to provide quantitatively controlled, chronologically optimized infusion. A motor causes bi-directional pumping to allow for samples to be presented to the sensor area. The system accuracy allows for more concentrated medicines, as a sealed container can eliminate the need for diluting or withdrawing medicine to load a reservoir, and achieves extraordinary accuracy without error correcting software or expensive volumetric measurement and control systems.

InactiveUS20100099979A1Clear visualizationPrecise quantitative comparisonImage enhancementImage analysisSection planeSonification
It is described a virtual pullback as a visualization and quantification tool that allows an interventional cardiologist to easily assess stent expansion. The virtual pullback visualizes the stent and / or the vessel lumen similar to an Intravascular Ultrasound (IVUS) pullback. The virtual pullback is performed in volumetric data along a reference line. The volumetric data can be a reconstruction of rotational 2D X-ray attenuation data. Planes perpendicular to the reference line are visualized as the position along the reference line changes. This view is for interventional cardiologists a very familiar view as they resemble IVUS data and may show a section plane through a vessel lumen or a stent. In these perpendicular section planes automatic measurements, such as minimum and maximum diameter, and cross sectional area of the stent can be calculated and displayed. Combining these 2D measurements allows also volumetric measurements to be calculated and displayed.

The present invention uses spectroscopic tissue volume measurements using non-ionizing radiation to detect pre-disease transformations in the tissue, which increase the risk for this disease in mammals. The method comprises illuminating a volume of selected tissue of a mammal with light having wavelengths covering a pre-selected spectral range, detecting light transmitted through, or reflected from, the volume of selected tissue, and obtaining a spectrum of the detected light. The spectrum of detected light is then represented by one or more basis spectral components, an error term, and an associated scalar coefficient for each of the basis spectral components. The associated scalar coefficient is calculated by minimizing the error term. The associated scalar coefficient of the each of the basis spectral components is correlated with a pre-selected property of the selected tissue known to be indicative of susceptibility of the tissue for the pre-selected disease to obtain the susceptibility for the mammal to developing the pre-selected disease.
