Description

Medical imaging apparatus

Technical Field

The present utility model relates to a medical imaging apparatus, and more particularly, to a medical imaging apparatus capable of automatic positioning.

Background

In current health and disease examinations, a subject is typically required to lie down and be positioned to a predetermined scan center at the time of imaging, during an imaging scan using Magnetic Resonance (MR) imaging or Computerized Tomography (CT) imaging or X-ray imaging.

One prior art positioning method that uses laser markers. For example, when scanning is performed using a magnetic resonance apparatus, a subject is laid on the table surface of an inspection table, and a marker is provided on the subject. The operator makes a mark line on a coil on or under the body of the subject by operating a laser on the scanning device to vertically project the laser downward, and makes the mark line aligned with a marker provided on the subject, and since the laser marker is installed at a predetermined position of the scanning device and the distance of the track from the center of the scanning device is known, the distance from the marker point on the body of the subject to the center of the scanning device can be calculated accordingly. The operator then moves the subject to the imaging center based on the distance and begins a predetermined imaging sequence. In this method, the laser marker harms the eye of the subject due to radiation, which requires additional safety measures and devices.

In medical diagnosis, imaging examination is sometimes performed on a plurality of parts of a patient's body, and a plurality of detected parts are required to be provided. However, in the existing imaging apparatus, the operator can only locate one detected part at a time, so that after imaging one detected part is finished, the patient is often moved out of the imaging area by the examination bed, and then the examination bed is moved again to locate the next detected part on the patient.

Detailed Description

The present utility model will be further described in detail with reference to the following examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent.

For a clearer understanding of technical features, objects, and effects of the present utility model, a specific embodiment of the present utility model will be described with reference to the accompanying drawings. Like reference symbols in the various drawings indicate like elements.

As shown in fig. 1, the imaging apparatus comprises an examination table 10, a scanning device 20, a moving device 30 and a distance measuring device 18 and an indicating device 19, and a storage device 40.

The examination couch 10 includes a fixed bed frame 13 and a movable bed plate 12 thereon, the subject 14 is placed on the bed plate 12, and the moving device 30 can control the movement of the bed plate 12 at least in one direction Z (first direction) to move the subject 14 at the subject site 16 into the imaging region 22 of the scanning device 20. Meanwhile, when the detected part 16 enters the imaging region 22, the scanning device 20 performs an imaging operation on the detected part. The examination couch 10 and the scanning device 20 in the imaging apparatus may be existing devices, and their specific structures are not described again. In addition, the subject 14 is schematically shown as a human body in the drawings, and it will be understood by those skilled in the art that the subject may be any suitable subject for detection by imaging.

In this embodiment, as shown in fig. 1, a distance measuring device 18 is provided at the bottom of the bed frame 13 at the end of the examination bed 10 away from the scanning device 20, and the distance measuring device 18 can emit a signal for distance measurement in the Z direction (first direction). The distance measuring device 18 may be one of a laser distance measuring device, an infrared distance measuring device, an ultrasonic distance measuring device, a radar distance measuring device, and the like. When the couch 10 is in the position shown in FIG. 1 (first predetermined position), the distance measuring device 18 is at a distance L (first distance) in the Z direction from the center O of the imaging region 22. In the present embodiment, the first distance L may be measured by a distance L in the Z direction from the distance measuring device 18 to the other end of the couch plate 12 near the scanning device 20 ₀ Plus the distance Lp from the other end of the couch 12 to the center of the imaging region of the scanner 20.

The operator can place the indicating means 19 at a position of the bed frame 13 corresponding to the detected part of the detected body, in this embodiment the indicating means 19 is placed at the bottom of the bed frame 13 and at the same level as the distance measuring means 18. At this time, the distance measuring device 18 measures the distance Lr (second distance) in the first direction from the indicating device 19. Depending on the type of distance measuring device 18, the indication means may be a dedicated indication means such as a slider that can slide along the bed frame or be replaced with an operator's finger. The moving means 30 subtracts the second distance Lr from the first distance L to obtain a distance Lm by which the couch 10 should be moved, and controls the couch 12 to move by a distance Lm so that the examined region 16 is located at the center of the imaging region 22.

In this embodiment, the medical imaging apparatus further includes a storage device 40, and the operator measures the distances in the first direction between the distance measuring device 18 and the indicating device 19 for a plurality of detected parts of the same detected body, and obtains different moving distances of the plurality of detected parts, and stores the different moving distances in the storage device, so that after the inspection of one detected part is completed, only the relative moving distances between the detected parts need to be calculated according to the different moving distances for the plurality of different detected parts stored in the storage device, thereby enabling the inspection between the plurality of parts to be completed quickly and efficiently.
