(1991-01-01)Because of the way most available hardware gradiometers are designed and in view of the prediction, by theory, that the normal magnetic field component provides all available information on the intrinsic current source, ...
-
(1987-05-01)Brainstem auditory evoked potentials and oto-acoustic emissions have been recorded in 30 normal newborns and in 112 infants admitted to a special care baby unit as part of a study to determine whether these tests can be ...
-
(1982-08-01)Ears were examined otoscopically by one or more of five experienced observers who were each asked to decide whether a middle ear effusion was present. Their decisions were then ordered according to the probability, estimated ...
-
(1980-11-01)The absolute calibration, linearity, angular response and wavelength response of three different commercially available UVA meters have been evaluated. The meters exhibited wide variations in accuracy in determining UVA ...
-
(1990-02-01)Data from dynamic radiocolloid liver scintigraphy (DLS) have been analysed to calculate three indices of relative arterial to total hepatic perfusion. Ninety subjects have been studied, comprising 21 normals, 62 patients ...
-
(1985-11-01)The operation, design and performance of a microcomputer controlled spectrum overlap eraser and automatic sensitivity control (ASC) for a clinical mass spectrometer are described allowing calibration for up to eight ...
-
(1991-08-01)A computer controlled scanner has been used with a copper vapour laser for the treatment of vascular lesions and hyperpigmented lesions. The computer controls the position and speed of travel of the laser spot during ...
-
(1990-08-01)A portable system using a direct contact method for the measurement of ultrasonic velocity and broadband attenuation in bone is described (contact ultrasonic bone analyser, CUBA). Soft-tissue compensation is performed using ...
-
(1983-11-01)A dedicated cotside microcomputer unit is described. It is designed to collect and to display graphically all continuously recorded variables from an infant in a neonatal intensive care unit. The data are collected from ...
-
(1991-05-01)Acoustic pulse reflectometry is a relatively recent technique which allows the noninvasive measurement of human airways. The technique consists of guiding an acoustic impulse through the subject's mouth and into the airway. ...
-
(1982-05-01)Transcutaneous nerve stimulation as a non-invasive technique for the relief of pain is becoming very popular. The electrical characteristics of ten commercially available stimulators were examined. Particular attention was ...
-
(1991-08-01)A comprehensive protocol was developed for assessing urodynamics instrumentation and applied to eight commercial urodynamics systems obtained on short-term loan. Assessment covered the areas of design and construction, ...
-
A critical investigation of the measurement of the force required to dilate the human uterine cervix(1988-05-01)A system for objectively analysing the forces of dilation of the human uterine cervix was devised using a force sensing device linked to a BBC microcomputer. The computer program allowed easy recording, storage and analysis ...
-
(1983-05-01)A paper by W.R. Ip et al. (ibid., vol.3, p.151-4, 1982) is commented on by Dhawan. Dhawan says that although the computerised tomographic radioabsorptiometric method for monitoring end-tidal Xe concentration is promising, ...
-
(1987-11-01)A data collection system for gathering electrical impedance measurements from the human breast is described. The system consists of 16 electrodes which are held in a ring that encompasses the breast. The system, which is ...
-
(1981-02-01)A device is described for obtaining reproducible positioning of an L-shaped hot film anemometer probe in the great vessels.
-
(1988-11-01)Details of the design of obstetric forceps are important to ensure that they can be used safely for mother and baby. One of the most important measurements is the radius of the cephalic curve of the blades since if this ...
-
(1990-02-01)A device was constructed to measure infant head rotation during orienting reflexes to sound stimuli. An experiment was devices to compare the device output with visual observation of the infant. Four stimulus and four ...
-
(1983-02-01)The goniometer provides an immediate digital display of single-plane angles and is easy to use for assessment of the range of motion of a limb joint in the clinic.
