The Simple Function Point (SFP) method [1] is a lightweight Functional Measurement Method.. The Simple Function Point method was designed by Roberto Meli in 2010 to be compliant with the ISO14143-1 standard and compatible with the International Function Points User Group (IFPUG) Function Point Analysis (FPA) method.
Medical devices first came under comprehensive regulation with the passage of the Federal Food, Drug, and Cosmetic Act of 1938 (FD&C), [9] which replaced the earlier Pure Food and Drug Act of 1906. The FD&C allowed the FDA to perform factory inspections and prohibited misbranded marketing of cosmetic and therapeutic medical devices. [10]
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
Measuring tape: for length, height, head circumference and girth measurements Medical halogen penlight: to see into the eye, natural orifices, etc. and to test for pupillary light reflex, etc. Medical ultrasound: to create an image of internal body structures Nasogastric tube: for nasogastric suction or the introduction of food or drugs into ...
ISO 14971 Medical devices — Application of risk management to medical devices is a voluntary consensus standard, [1] published by International Organization for Standardization (ISO) for the first time in 1998, and specifies terminology, principles, and a process for risk management of medical devices.
An anesthetic machine with integrated systems for monitoring of several vital parameters, including blood pressure and heart rate. Monitoring of vital parameters can include several of the ones mentioned above, and most commonly include at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate.
Arterial input function (AIF), also known as a plasma input function, refers to the concentration of tracer in blood-plasma in an artery measured over time. The oldest record on PubMed shows that AIF was used by Harvey et al. [1] in 1962 to measure the exchange of materials between red blood cells and blood plasma, and by other researchers in 1983 for positron emission tomography (PET) studies.
The two-dimensional Fourier transform of an edge is also only non-zero on a single line, orthogonal to the edge. This function is sometimes referred to as the edge spread function (ESF). [9] [10] However, the values on this line are inversely proportional to the distance from the origin. Although the measurement images obtained with this ...
