This method was applied to calibrate the sensitivity of a GE Typhoon FLA 7000 scanner. Additionally, we performed a calibration of the spontaneous signal attenuation behavior for BAS-MS, BAS-SR, and BAS-TR type IPs under the 20±1℃ environmental conditions, and observed significant signal carrier diffusion behavior in BAS-MS IP. The calibration results lay a foundation for further research on the interaction between ultra-short, ultra-intense lasers and matter.展开更多

Methods: Eighty patients admitted to our hospital from March 2023 to March 2024 were selected, all of whom were acute abdomen patients admitted to the Department of Obstetrics and Gynecology. In this study, the patients were divided into two groups. One group of 40 patients was given a simple abdominal B-ultrasound diagnosis (control group). The other group of 40 patients was given both abdominal and vaginal B-ultrasound examinations (experimental group). The diagnostic accuracy between the two groups was compared. Results: Patients in the experimental group had higher consistency rates with pathological diagnosis results in ectopic pregnancy rupture, embryonic arrest, acute pelvic inflammation, corpus luteum rupture, and intrauterine adhesions as compared to the control group. At the same time, the inspection accuracy rate of the experimental group (92.50%) was higher than that of the control group (70.00%) (P < 0.05). Conclusion: The combined application of abdominal and vaginal B-ultrasound in the diagnosis of acute abdomen was of great significance in improving the accuracy of clinical diagnosis and guiding doctors to provide effective treatment.展开更多
