Definitions

  • the present disclosure relates in general to the field of a radiological imaging system, and in particular, to an imaging table for greater access to patient region of interest and systems/methods incorporating the foregoing.
  • Radiological imaging devices currently available on the market have a standard structure including a flatbed on which a patient is placed in order to perform image scanning of the patient.
  • the bed is typically fitted with straps to restrain the patient.
  • the straps may prevent the passage of the X-rays and thereby the correct visualization of the portions adjacent to the straps.
  • the straps covering a portion of the area of interest are practically unusable, and the patient may be required to stay still or held by the operator, who is therefore exposed to the X-rays.
  • the radiological imaging device may require a specific detector for each analysis and can perform only one type of analysis at a time.
  • a patient may need to be repositioned for optimal imaging or to allow personnel, such as a physician, to gain access to the patient region of interest without removing the patient or the bed from the radiological imaging device.
  • the bed of existing imaging devices does not allow easy maneuverability of patients, especially when the patient is secured to the bed by straps or restraints. Consequently, the length of time needed to perform the aforementioned maneuvers increases.

L'invention concerne un système d'imagerie radiologique comprenant un portique qui définit une zone d'analyse, une source logée à l'intérieur du portique et un détecteur logé à l'intérieur du portique. Une partie d'un patient est placée dans la zone d'analyse. La source émet un rayonnement qui traverse ladite partie du patient; le détecteur reçoit le rayonnement. Le système est conçu pour recevoir le patient en alternance dans au moins deux des agencements suivants : un agencement comprenant un lit fixe et un portique mobile, un agencement comprenant un lit pourvu d'un plateau de table qui se déplace à travers la zone d'analyse le long d'une direction principale et un agencement dans lequel le patient peut être dans un dispositif d'assise ou inclinable.
