Definitions

  • the present invention relates to a method of projecting a position of a so-called ground glass-like lesion in a lung field found by an X-ray CT examination on an X-ray fluoroscopic image.
  • An object of the present invention is to perform endoscopic sampling of ground glass-like lesions using an X-ray TV fluoroscopy device that is widely used, not an expensive CT device!
  • a laysum image is created from three-dimensional image data of a region of interest, for example, the chest acquired by an X-ray CT apparatus.
  • the Latham image is the sum of CT values on the projection line that penetrates the subject.
  • a three-dimensional 3D image is projected as a 2D image on a single plane.
  • the lesion area is emphasized by techniques such as masking the lesion area (a process that is excluded when creating the laysum image) and changing the CT value so that the lesion area can be visually recognized. It is preferable to make corrections.
  • This latham image is superimposed on a chest fluoroscopy image obtained from an X-ray TV fluoroscopy device to obtain a composite image.
  • a chest fluoroscopy image obtained from an X-ray TV fluoroscopy device to obtain a composite image.
  • an image seen from an oblique direction is created only from the front image, and the image corresponding to the X-ray fluoroscopic angle at that time is selected and superimposed.
  • the Latham image is intermittently superimposed on the fluoroscopic image. If this is the case, the lesion on the composite image will appear to blink, so it is visible.
  • the endoscope While monitoring such a composite image, the endoscope is inserted toward the lesion, and a photograph of the lesion, biological sampling, etc. are performed while confirming the positional relationship between the distal end of the endoscope and the lesion.
  • the X-ray CT apparatus which is an expensive apparatus, is used only when acquiring three-dimensional image data, and thereafter, a normal X-ray fluoroscopic apparatus is used to visualize the disease. This has the effect of enabling mirror diagnosis and sampling of the lesion.
  • FIG. 1 is a block diagram showing the method of the present invention.
  • FIG. 2 An image comparing CT scan and fluoroscopy.
  • Reference numeral 1 denotes an X-ray multi-slice CT apparatus, which acquires 3D image data of a subject, processes it by a computer, and performs arbitrary processing. A cross-sectional image can be displayed on the monitor.
  • 3D image data is taken from the multi-slice CT apparatus 1 into the image processing apparatus 3 to create a laysum image.
  • a Latham image is a two-dimensional fluoroscopic image similar to an X-ray fluoroscopic image, and is obtained by adding CT values on a projection line that penetrates the subject.
  • the 3D image data obtained by the CT device is a collection of CT values arranged at each intersection of the 3D grid. If the CT values are added in the vertical direction, X-ray fluoroscopy is performed. You can create a composite image that looks similar to the image.
  • the X-ray fluoroscopic image is obtained by radiating the X-ray from the X-ray source 2a in a conical shape and reaching the projection surface. There will be a gap with Iji. Therefore, in order to obtain a Latham image, a projection line 7 of the fluoroscope that runs in the perpendicular direction is assumed, and CT values are added along that line.
  • Latham image A created in this way is superimposed on fluoroscopic image B obtained from X-ray fluoroscopic apparatus 2 to obtain composite image C. If this image C is monitored, the ground glass-like lesion 4 can also be visually recognized.
  • the diaphragm shown in the Latham image A is fixed at the inhalation position. Therefore, there is little misalignment when superimposing is performed with the patient in his / her fluoroscopy holding his breath and stopping.
  • Latham image A that is, a deeply processed lesion and a thinly processed one, and alternately superimpose them on X-ray fluoroscopic image B.
  • the method also has good visibility because the lesion appears to blink.
  • the Latham image A is also created for each angle viewed from an oblique direction only in the front position, and the image processing device 3 obtains the angle information of the arm at that time from the X-ray fluoroscopic device 2. Receive the same angle Latham image and superimpose it on the fluoroscopic image B.
  • the composite image C clearly shows the force and the position of the affected lesion in the image B of the X-ray fluoroscope 2, so the bronchoscope 6 is inserted while gazing at the image C. Then, the leading end can reach the lesion 4 to take a photograph or sample a lesion.

Abstract

L'invention concerne une image de somme de rayons (A) créée à partir de données d'image tridimensionnelle de poitrine collectées par un appareil CT à rayons X (1). Une correction pour mettre en valeur le contraste d'une région de lésion est réalisée pour faire en sorte que la lésion soit facilement reconnue visuellement. L'image de somme de rayons (A) est superposée sur une image fluoroscopique de poitrine (B) acquise par un appareil fluoroscopique TV à rayons X (2) pour obtenir une image combinée (C). Si l'image de somme de rayons est superposée de manière intermittente sur l'image fluoroscopique à rayons X, la lésion (4) dans l'image combinée clignote, de sorte que la lésion (4) peut facilement être reconnue visuellement. Tout en surveillant une telle image combinée (C), un endoscope (6) est inséré vers la lésion. Tout en confirmant la relation positionnelle entre l'extrémité de l'endoscope et la lésion, la lésion peut être imagée ou un bio-échantillon peut être prélevé.
