Image-processing equipment and medical diagnostic imaging equipment

Abstract

The image-processing unit (16) of an embodiment is provided with an expansion unit (161), a decomposition unit (162), a data-processing unit (163), a reconstruction unit (164), and a contraction unit (165). The expansion unit (161) expands the data to be processed with a magnification that is based on the optimal sample number, which is the ideal number of samples per unit length for image-processing. The decomposition unit (162) decomposes the expanded data using multiresolution analysis to generate data sets with the optimal number of samples. The data-processing unit (163) performs image processing on the data sets with the optimal number of samples to generate processed data sets. The reconstruction unit (164) reconstructs the processed data sets using multiresolution analysis to generate reconstructed data. The contraction unit (165) contracts the reconstructed data so that the number of samples per unit length equals the number of samples per unit length of the data that was processed.

Description

technical field [0001] Embodiments of the present invention relate to an image processing device and a medical image diagnosis device. Background technique [0002] Conventionally, various types of image processing are performed in medical image diagnostic devices such as ultrasonic diagnostic devices, X-ray diagnostic devices, X-ray CT (Computed Tomography) devices, and MRI (Magnetic Resonance Imaging) devices. For example, as image processing, there are smoothing processing and filtering processing for noise reduction. [0003] However, if the actual length per sample in the data to be image processed is different, the effect of the image processing will change. For example, even if the number of pixels per unit length differs between two pieces of image data depicting the same photographic object, the effect of the image processing performed on each piece of image data will be different.

[0003] However, if the actual length per sample in the data to be image processed is different, the effect of the image processing will change

For example, even if the number of pixels per unit length is different in two image data depicting the same subject, the effect of image processing performed on each image data will be different.
