| 摘要 |
The invention concerns a method for reducing exposure to infrared light beam, ultrasound or magnetic impulse rays (1) in a body, in medical imaging devices, through modification of the treatment process of the signal so as to obtain images representing values associated with each term or zone of a planar or non-planar surface, which consists in: producing a first image for retaining an estimate of the value associated with each point or zone of a rectangular matrix; evaluating by interpolation values between two points or by distribution of the value of a zone into micro-zones, resulting from the division of the zone, to obtain an amplified matrix from the initial matrix; measuring by physical scans (19) along cross-series exploring the examined area (20), the variation between the two ends of each scanning so as to calculate the values of the edges of the matrix; and adjusting the value of each term using an adjustment by the least squares method taking into account the edge-related constraints, so as to obtain a finer resolution of the image. |
