摘要:
A system for tracking the position of an instrument relative to an area of interest includes a first fixator configured to carry first and second localizing devices. A second fixator is configured to carry the first localizing device. A third localizing device communicates with the first localizing device and the second localizing device communicates with the first localizing device such that the position of the second localizing device can be determined relative to the position of the third localizing device. The second localizing device is attachable to the instrument and the first localizing device is attachable to the first fixator such that the first localizing device communicates with the second localizing device on the instrument in order that the position of the second localizing device on the instrument can be determined relative to the third localizing device.
摘要:
The present invention relates to a device for displaying X-ray images of an object, preferably in connection with surgical orthopaedic operations, wherein X-ray images of the object are generated by means of at least a first and a second X-ray device ( 19, 20 ). The first X-ray device ( 1 )=is provided to X-ray the object in a first plane (P 1 ) and the X-ray images obtained thereby are displaced on a first screen ( 28 ) and the second X-ray device ( 20 ) is provided to X-ray the object in a second plane (P 2 ) and the X-ray images obtained thereby are displayed on a second screen ( 30 ). An automatic image changing device (AC) includes an image alternator ( 54 ) which is provided to automatically change the display of moving images of the object taken in one plane (P 1 ) on the first screen ( 28 ) to display of moving images of the object taken in the other plane (P 2 ) on the second screen ( 30 ) and vice versa, such that it becomes possible to see moving X-ray images of the object taken in the two different planes (P 1 and P 2 ) close behind each other. Each receiver ( 22 and 24 respectively) in each X-ray device ( 19 and 20 respectively) is linearly displaceable relative to the associated transmitter ( 21 and 23 respectively) and/or each transmitter ( 21 and 23 respectively) is linearly displaceable relative to each receiver ( 22 and 24 respectively) for varying the distance between each receiver ( 22 and 24 respectively) and transmitter ( 21 and 23 respectively).

A method of displaying a motion image of an object includes a phase recognition step of recognizing a phase in a series of moving states of the object for each of images constituting the motion image by analyzing the motion image, and a motion image displaying step of displaying the motion image using the images constituting the motion image in accordance with the phase recognized in the phase recognition step.
摘要:
A radiographic apparatus or system for imaging a dynamic state or process of an object such as a human body includes an indication unit for performing dynamic state guiding indication using a perceivable pattern corresponding to a dynamic state or motion to be engaged in by the patient, and an image acquisition unit for acquiring a plurality of radiographs of the human body. The resulting radiographs can be reviewed for diagnosis, and can be stored, either locally or at a remote location.

To achieve a relative motion between a patient support and an X-ray source and X-ray receiver, the X-ray source and receiver are moved separately but synchronously to one another.
摘要:
Procédé et appareil de tomographie permettant de reconstituer un autre plan que le plan principal de tomographie en exploitant les signaux numériques qui ont permis de visualiser ledit plan principal, c'est-à-dire sans soumettre le patient à une nouvelle irradiation. Selon l'invention, le signal vidéo numérisé (150, 151) subit un traitement pixel par pixel consistant en un décalage (200) des adresses des pixels puis un filtrage récurrent (300). L'invention s'applique à la tomographie numérique.
摘要:
L'invention concerne un statif radiologique intégré comprenant essentiellement un tube à rayons X (3) et un sériographe (7) disposés sous un panneau porte-patient (6). Le tube à rayons X (3) coopère avec un amplificateur de luminance (20) extérieur au statif, et le sériographe (7) avec un tube à rayons X (26) également extérieur au statif; ces moyens sont agencés de telle sorte que le sériographe (7) peut se superposer au tube à rayons X (3), ce qui permet le passage rapide d'une phase de travail en radioscopie à une phase de travail en radiographie et réciproquement. L'invention s'applique notamment aux examens radiologiques vasculaires.
