Design outcomes

Primary

MeasureTime frame
Availability of intraoperative identification of target lesions by intra-thoracic ultrasonography.

Secondary

MeasureTime frame
I. Secondary Endpoints of Efficacy 1. retrospective data (to obtain data that occur prior to the start of the study), including patient background prior to the examination and examination results will be followed to the extent possible as an exploratory endpoint. 2. findings: the size of the pulmonary nodular lesion, the distance of the lesion from the pleural surface, and ultrasound findings of the lesion will be recorded. 3. 3) Setting conditions during lesion delineation: Record the settings of the device while the tumor is being delineated. 4) Examination time: Record the duration of the examination when the probe is being moved to the lesion. 4. examination time: measure the time from insertion of the probe into the thoracic cavity to identification of the lesion; 5. record the condition of the lungs at the time of examination 5. recording the condition of the lungs at the time of examination. 6. record the examination and surgical procedures. 7. 7. time from the start of isolated pulmonary ventilation to the identification of the lesion. 8. pathological results. 8. pathologic results: results of resection margins, histology, and background pulmonary findings on pathology. II. secondary safety endpoints 1. intraoperative adverse events are to be identified. 2. 2. verification of the cause of failure to identify the lesion by ultrasound.
