Dynamic analysis system

A dynamic analysis system comprising a hardware processor that:

• based on a first plurality of frame images showing a dynamic state of a chest of an intubated first examinee obtained by radiation imaging of the chest of the first examinee, calculates a signal value change amount and/or a shape change amount of a predetermined structure of the chest in the first plurality of frame images;
• based on the calculated signal value change amount and/or shape change amount, generates assessment information to assess a respiratory status of the first examinee at time of intubation or extubation;
• obtains attribute information and/or vital information at the time of extubation about the first examinee;
• and
• into a machine learning classifier constructed based on the signal value change amount and/or the shape change amount and the attribute information and/or the vital information at the time of extubation and a success/failure result of spontaneous breathing after extubation about a second examinee, inputs the signal value change amount and/or the shape change amount and the attribute information and/or the vital information at the time of extubation about the first examinee, and calculates a success rate of spontaneous breathing after extubation for the first examinee, thereby generating the assessment information to assess the respiratory status of the first examinee at the time of extubation.

• based on the calculated signal value change amount and/or shape change amount, generates assessment information to assess a respiratory status of the first examinee at time of intubation or extubation;
• based on a second plurality of frame images showing the dynamic state of the chest of the first examinee before intubation, calculates the signal value change amount and/or the shape change amount before intubation about the first examinee;
• based on the first plurality of frame images showing the dynamic state of the chest of the first examinee after intubation, calculates the signal value change amount and/or the shape change amount after intubation about the first examinee;
• and
• based on the calculated signal value change amount and/or shape change amount before intubation and the calculated signal value change amount and/or shape change amount after intubation about the first examinee, generates the assessment information to assess the respiratory status of the first examinee at the time of intubation.

• performs a comparison of the calculated at least one of the signal value change amount and the shape change amount with statistical data of the at least one of the signal value change amount and the shape change amount calculated about a second examinee;
• and
• based on the comparison, generates assessment information to assess a respiratory status of the first examinee at time of intubation or extubation,
• wherein the statistical data used in generating the assessment information to assess the respiratory status of the first examinee at the time of intubation includes statistical data of the at least one of the signal value change amount and the shape change amount about the second examinee who has succeeded in ventilator breathing and statistical data of the at least one of the signal value change amount and the shape change amount about the second examinee who has failed in the ventilator breathing, and/or
• wherein the statistical data used in generating the assessment information to assess the respiratory status of the first examinee at the time of extubation includes statistical data of the at least one of the signal value change amount and the shape change amount about the second examinee who has succeeded in spontaneous breathing after extubation and statistical data of the at least one of the signal value change amount and the shape change amount about the second examinee who has failed in the spontaneous breathing after extubation.
