Arteriosclerosis detection system

An arteriosclerosis detection system comprising:

• electrocardiographic signal detection means for detecting an electrocardiographic signal;
• eyeground image detection means for continuously or discontinuously detecting an eyeground image in synchronization with an electrocardiographic signal detected by the detection means;
• and
• eyeground vein constriction detection means for detecting the constriction of an eyeground vein by using a ratio of an outer diameter of the eyeground vein in the vicinity of a site at which the eyeground vein and an eyeground artery cross each other to a portion of a eyeground vein distant from the crossing site,
• wherein the system is operable to detect the constriction of the eyeground vein based on the eyeground image detected in synchronization with the electrocardiographic signal, and
• wherein the system is operable to detect the eyeground image using software which can provide an eyeground image synchronized with an electrocardiographic signal by obtaining, by use of a computer, a stationary eyeground image synchronized with an arbitrary electrocardiographic signal from an animated eyeground image.

A method of detecting arteriosclerosis, the method comprising:

• detecting an electrocardiographic signal;
• continuously or discontinuously detecting an eyeground image in synchronization with the detected electrocardiographic signal;
• and
• detecting constriction of an eyeground vein by using a ratio of an outer diameter of the eyeground vein in a vicinity of a site at which the eyeground vein and an eyeground artery across each other to a portion of the eyeground vein distant from the crossing site,
• wherein the constriction being detected on basis of the eyeground image detected in synchronization with the electrocardiographic signal.
