Abstract
A bone growth stage analysis method according to an embodiment of the present application includes acquiring a medical image including a bone region, detecting regions of interest in the medical image, calculating a skeletal maturity index for each of the regions of interest, calculating a temporary growth stage on the basis of the skeletal maturity index, calculating a bone age from an entire area of the medical image, acquiring correlation information between bone ages and bone growth stages and calculating a reference growth stage corresponding to the calculated bone age using the correlation information, and calculating final bone growth stage information on the basis of the temporary growth stage and the reference growth stage.
Claims7
A method for a bone analysis device to analyze a bone growth stage, the method comprising:
- acquiring a medical image including a bone region;
- detecting regions of interest in the medical image;
- calculating a skeletal maturity index for each of the regions of interest;
- calculating a temporary growth stage on the basis of the skeletal maturity index;
- calculating a bone age from an entire area of the medical image;
- acquiring correlation information between bone ages and bone growth stages and calculating a reference growth stage corresponding to the calculated bone age using the correlation information;
- and
- calculating final bone growth stage information on the basis of the temporary growth stage and the reference growth stage,
- wherein the calculating of the final bone growth stage information comprises:
- detecting a correction event of the calculated temporary growth stage, and
- acquiring the final bone growth stage information by correcting the temporary growth stage on the basis of the reference growth stage when the correction event is detected and determining the calculated temporary growth stage to be the final bone growth stage information when the correction event is not detected,
- wherein the calculating of the skeletal maturity index for each of the regions of interest comprises:
- acquiring an artificial intelligence model for which training has been completed, and
- acquiring a probability value that each of the regions of interest will correspond to a subclass of the skeletal maturity index through the artificial intelligence model for which training has been completed,
- wherein the skeletal maturity index is a skeletal maturity indicator (SMI) including a plurality of subclasses based on whether a diaphysis area is equal to an epiphysis area, whether an epiphysis covers a diaphysis, or whether an epiphysis is fused, and
- wherein the detecting of the correction event of the calculated temporary growth stage comprises:
- determining whether the plurality of subclasses of the SMI are inconsecutively calculated,
- determining that there is the correction event for the calculated temporary growth stage based on the plurality of subclasses of the SMI being determined as inconsecutively calculated, and
- determining that there is no correction event for the calculated temporary growth stage based on the plurality of subclasses of the SMI being determined as consecutively calculated.
