Abstract

PURPOSE:To markedly enhance user's convenience, by receiving the imaging data obtained by photographing a subject to perform imagewise reconstitution and displaying the animation image obtained by said imagewise reconstitution on a monitor and simultaneously recording the same on a video recorder. CONSTITUTION:A display controller 1 receives the imaging data from a data collecting part 2 to perform operation for imagewise reconstitution at a high speed and successively transmits the final result by said operation to a monitor 3 to display a real time image on the monitor 3. At the same time, the real time image is recorded on a video recorder 3 on-line. Further, the real time image recorded on the video recorder 4 can be again imagewise displayed on the monitor 3. Therefore, the display controller 1, the data collecting part 2, the monitor 3 and the video recorder 4 are mounted and an operating part 5 having the monitor 3 and the video recorder 4 arranged thereto is constituted. As a result, the real time image imagewise displayed on the monitor 3 at an imaging time can be preserved on the video recorder 4 without being deteriorated.

Description

Detailed Description of the Invention (Objective of the Invention) (Industrial Application Field) The present invention relates to magnetic resonance imaging (hereinafter referred to as an MRI apparatus), and particularly relates to a technology for displaying or recording contents corresponding to imaging data. Regarding improvements.

(Prior art) With recent advances in image processing technology, this type of MRI
It has also become possible for devices to reconstruct photographic data at high speed and display real-time images corresponding to the photographic data on a monitor.

However, in the case of the conventional MR4 apparatus of this type, still images are recorded for image storage, making the operator inconvenient in handling.

(Problem that i-mei is trying to solve) In other words, this type of MRI device has excellent ability to extract blood vessels, so in recent years, it has become possible to monitor the blood flow situation as the heart moves in real time. If this can be done, the diagnostic ability of the operator can be improved.

However, if the image to be stored is a static image as in the past, it is not possible to reproduce a real-time image showing the blood flow condition associated with the movement of the heart due to eye shadow invasion. Therefore, when the operator wanted to examine the real-time image again, he had to photograph the subject again. Therefore, there are disadvantages in that the operator feels troublesome in handling, and the subject is given a feeling of mental and physical pain. [Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention reconstructs an image by receiving photographic data obtained by photographing a subject, and performs image reconstruction. The gist of the present invention is to include a display controller that displays a moving image obtained by the above on a monitor and records the moving image on a video recorder at the same time.

(Function) With the configuration according to the present invention, a moving image showing the blood flow status of the subject can be reproduced on a general video monitor after testing, so the usability of this type of MRfail is significantly improved. Ru.

(Embodiment) FIG. 1 is a block diagram showing the main part configuration of an MR1 apparatus according to an embodiment to which the present invention is applied.

In the MHI device of this embodiment, a data collection unit 2 sequentially collects photographic data from a high-speed scanner (not shown) and sends the data to a display controller.

When the display controller 1 receives the photographic data from the data collection unit 2, it performs image reconstruction calculations at high speed, sequentially transfers the final results of this calculation to the monitor, and displays a real-time image on the monitor 3. . At the same time, real-time images are recorded online on the video recorder 4. Further, the real-time image recorded on the video recorder 4 can be displayed on the monitor 3 again.

Therefore, the above-mentioned display controller 1゜data collection section 2. By configuring the operation section 5 in which the monitor 3 and video recorder 4 are installed as shown in FIG. 2, images can be displayed on the #ll standby monitor 3. The real-time image obtained can be stored in the video recorder 4 without deterioration. After the dance is completed, the real-time image can be displayed on the monitor 3 again. As a result, the operator's usability is significantly improved compared to the conventional method, and the subject's mental and physical pain can be reduced.

Further, by providing the above-mentioned display and switches for starting recording, recording and reproducing, etc. on the operation unit 5 so that the operator can easily operate them, the burden on the operator is further reduced.

Furthermore, even when high-speed scanning is not used, moving images can be recorded and reproduced, and can be recorded and reproduced as real-time images as needed.

〔Effect of the invention〕

As explained above, since the MRI apparatus of the present invention can display moving images on a monitor and record the moving images on a video recorder at the same time, the usability is significantly improved compared to the conventional one, and the It is possible to significantly reduce the troublesome handling of the patient and the rate of mental or physical pain experienced by the subject. Furthermore, it becomes possible to play back on a general video playback device, making it possible to diagnose using moving images outside the imaging room.
