Description

Medical Photographing Apparatus for Blood Vessel Image}

The present invention relates to a medical blood vessel imaging apparatus, and more specifically, to photograph the blood vessels of the target body by equipping each of the photographing unit with an illumination unit for irradiating near-infrared rays based on the body to which the blood vessel image is to be photographed and the image. It relates to a medical vascular imaging apparatus that can be used for diagnosis and treatment.

In general, a method of acquiring a blood vessel image of a body includes a method using magnetic resonance imaging (MRI) and computed tomography (CT).

However, when taking blood vessel images using the above methods, there is a problem in that a contrast agent must be used.

Here, the contrast agent is a substance that can more clearly represent a specific portion of the blood vessels in the image taken when radiographic imaging, such as MRI or CT, the user using it is cumbersome due to the administration of the contrast agent, side effects to some users May result.

In addition, the radiation of the vascular imaging apparatus using the radiation has a higher energy than visible light, unlike the visible light can pass through the human body and affect the irradiated body tissue, unlike the visible light, There is a problem that it is difficult to continuously photograph the body parts over a large number.

Moreover, since radiography such as MRI or CT cannot be performed in real time, it takes a long time to acquire an image, which makes the diagnosis and treatment of the patient uncomfortable, and because the cost is expensive, general diagnosis except for special purposes is required. And difficulty in use for therapeutic purposes.

On the other hand, as another method for taking the blood vessel image, there is a device using a laser Doppler effect or a device using ultrasound, which is expensive because the device is difficult to hold such a device in a small / medium hospital, electrical Since the signal is converted into an image, when the signal includes noise, it is difficult to make an accurate medical judgment through the blood vessel image.

The above-described prior art has a problem in that accuracy is low when detecting an image of a thin blood vessel tissue such as a finger vessel.

The present invention provides a medical vascular imaging apparatus that can be installed so as to oppose each other on the basis of the body to shoot the illumination unit for irradiating near-infrared and the image taking unit for taking an image.
