A non-transitory computer-readable medium storing a computer program executed by a computer processor to execute a process including: acquiring a medical image generated based on a signal detected by a catheter inserted into a luminal organ; detecting an object region included in the medical image by inputting the acquired medical image into a model trained for detecting the object region included in the medical image; calculating reliability of each of a plurality of boundary points located on a boundary between the detected object region and another image area in the medical image; and correcting the boundary based on a detection result of the object region by the model by performing interpolation using the boundary points at which the calculated reliability satisfies a predetermined standard.

Program, information processing device, and information processing method

A diagnostic method, a diagnostic system, and a control method of a diagnostic system that can detect specific behavior of an elongated body easily and with high accuracy are provided. The diagnostic method is a diagnostic method for diagnosing the behavior of a guiding catheter having a distal end and a proximal end in a biological lumen. The diagnostic method includes inserting the guiding catheter into the biological lumen from the distal end and detecting energy that has passed through a body after irradiating the inside of the body with the energy. The diagnostic method also includes identifying the position of the guiding catheter in the body by the detected energy and comparing the identified position of the guiding catheter with an expected position and detecting specific behavior of the guiding catheter from an amount of deviation of the position of the guiding catheter with respect to the expected position.

Diagnostic method, diagnostic system, and control method of diagnostic system

A method is disclosed for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a lower stenosis rate lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a higher stenosis rate lesion is to be treated next, then treating the lesions substantially continuously.

Diagnostic method, method for validation of diagnostic method, and treatment method

A method is disclosed for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a lesion distal to an aortailiac bifurcation is to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a lesion proximal to the bifurcation is to be treated next, then treating the lesions substantially continuously.

In a method for diagnosing, validating and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a smaller curvature of lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a larger lesion curvature is to be treated next, then treating the lesions substantially continuously.

A medical assistance device capable of improving handling or an operation of a medical device. The medical assistance device is connected to the medical device which is inserted into a biological lumen and is used in a procedure in the biological lumen. The medical assistance device includes a support, a winding unit which is rotatably provided about a support shaft with respect to the support and winds the medical device, and a connection section which is provided in the winding unit and is connected to an end portion of the medical device.
