摘要： A compliant coupling mechaism has a first part (10) connectable to a robot arm (A) and a second part (20) connectable to a robot gripper (G). The mechanism is arranged to allow displacement of the second part relative to first part along a ZZ axis direction, and to allow further relative displacement along and/or about (XX) and (YY) axis directions. A locking device (40) prevents such further relative displacement unless a displacement along the (ZZ) axis direction exceeds a preset amount.

摘要： In a control system for a robotic gripper a processing circuit (10) controls movement of the gripper (20) on a prearranged path. An article (A) held by gripper (20) comes into contact with the probe member (32) of a "known-down" sensor (30). A support assembly (33), on which the probe member (32) is mounted, is displaced with respect to a base member (31) allowing a continuous, uninhibited movement of the gripper along the path, even after contact has been established. In an alternative arrangement the sensor is mounted on the gripper and establishes contact with an article located at a fixed work station.

摘要： In Nuclear Magnetic Resonance (NMR) imaging systems it is known to excite resonance in a slice of a body and to sample the resonance signals in the presence of a field gradient across the slice. The gradient field is pulsed. Where such systems analyse the signal to be for many sets of strips in the slice, each set in a different direction, for analysis by techniques used in computerized tomography (CT) X-ray systems, it is now proposed that the field gradient pulsed should reach a maximum after not more than one third of its total duration to balance the spatial frequency emphasis (FIG. 1e) in the CT processing.

摘要： Computerized tomographic apparatus is described in which a radiation source and an associated detector array execute, concomitantly, reciprocating lateral scanning movements and rotational scanning movements relative to a patient's body, the scanning movements being effected in the plane of a cross-sectional slice of the body which intersects the patient's heart. The patient is located so that the heart is substantially at the center of the scanning movements. The lateral movements are substantially sinusoidal, arranged so that a substantially linear portion of the movement occurs when the source irradiates the heart, and the rotational movement is continuous or substantially continuous and any pauses are only brief, and during alternate lateral scans when the aforementioned substantially linear portions of movement occur. The scanning movements are synchronized to the patient's heart beats so that the heart is irradiated during a quiescent phase of its movement.

摘要： In a computerized tomographic apparatus, different detectors are caused to receive radiation along substantially the same beam path through the body in order to permit the evaluation of differences in performance of the detectors. This evaluation is average with other evaluations made in respect of the same detector for other beam paths so as to reduce the risk that erroneous performance differences may be evaluated in the event that any of the relevant beam paths lies adjacent a bone edge in a patient's body. Also disclosed are techniques for electronically deflecting the radiation so that part at least of the radiation is taken clear of the body and can be detected to provide reference signals.

摘要： In nuclear magnetic resonance (NMR) imaging systems it is known to excite resonance in a slice of a body and then to sample the resonance signals in the presence of a field gradient across the slice. It has been proposed that the signals should be sampled at intervals such that there is equal field integral (for the field gradient) in each interval. It is now proposed to use outputs from two NMR probes in the slice and on opposite sides of the body. The phase difference between the two probes is measured and samples are taken when the phase difference reaches a predetermined value. Preferably the samples are taken when a gate detects zero-crossing of the output of a demodulator providing the phase difference. Two probes only may be rotated around the patient as the field gradient rotates or four may be used, two orthogonally disposed pairs and one or other appropriately weighted output used.

摘要： In NMR imaging systems a pulsed field gradient may be applied across an excited slice (1) and the resonance signal detected during the field gradient pulse. It has been usual to demodulate the resonance signal at the Larmor frequency for a strip at the center of the slice, at which generally the field gradient has a zero-crossing. It has, however, been proposed to put the zero-crossing outside the slice, still demodulating at the slice Larmor frequency. In this invention demodulation is actually at the frequency for a probe (12) which is necessarily outside the patient. This makes the demodulation independent of errors in a local oscillator frequency. Demodulation may be for a probe effect to give a frequency for a strip outside the slice or the probe may be perpendicular to the gradient to give the zero-crossing frequency.

摘要： In a computerized tomographic apparatus in which the requisite absorption data are derived by rotating a source of fanned radiation around a body to be examined and detecting radiation emergent from a cross-sectional slice of the body at many times during the rotation the data, when assembled into sets relating to parallel beam paths through the slice, tends to relate to beam paths which are non-uniformly spaced across the slice. Some techniques for processing such data to produce a representation of the variation of absorption of said radiation over the slice should preferably have said data presented thereto in the form of sets relating to substantially uniformly spaced, parallel beam paths. The application of this invention provides considerably more data then is actually required for the processing so that data relating to beam paths of the required numbers and dispositions can be derived therefrom.

摘要： In a computerised tomographic (CAT) X-ray apparatus passage of the radiation through high absorption (bone) regions can change a characteristic of the radiation, such as its frequency spectrum. This can introduce error into the final representation. Correction is provided by computing a first representation, identifying areas of bone and then determining corrections for those areas which can be used to provide a subsequent move accurate representation. Errors caused by scattering can also be compensated in this way.
