Title:
医用画像処理装置、医用画像処理方法、およびプログラム
Document Type and Number:
Japanese Patent JP7093075
Kind Code:
B2
Abstract:
A medical image processing device of an embodiment includes a first position acquirer, a first converter, a first likelihood image generator, and a learner. The first position acquirer is configured to acquire, as first positions, target positions in a plurality of first images. The first converter is configured to convert the first positions to second positions by expanding movement in a second direction intersecting a first direction in which movement over time of the first positions is large. The first likelihood image generator is configured to generate a first likelihood image showing a distribution of likelihood of the second positions on the basis of the second positions. The learner is configured to output a model which uses the plurality of first images and the first likelihood image as training data, and upon receiving part or all of a transparent image, derives a second likelihood image showing a distribution of likelihood indicating probability of the part or all of the transparent image corresponding to the second positions.
