[Performance Evaluation Methods and Suggestions for High-Voltage Generator and Tube of DR System].

In the design of DR systems, high-voltage generators and X-ray tubes are two key components whose performance directly affects the system's exposure capabilities. This article first explains why it is necessary to conduct an in-depth evaluation of the performance of these two parts during the design of DR products. Then, it provides a detailed description of the evaluation methods, including the assessment of single exposure capability and continuous exposure capability.

Prussian blue nanoparticles coated with tumor cell membranes for precise photothermal therapy and subsequent inflammation reduction.

The utilization of photothermal agents (PTAs) in photothermal therapy (PTT) is faced with challenges such as immune clearance and inadequate concentration, which consequently result in residual tumors and an increased risk of recurrence and metastasis. Conversely, excessive treatment can lead to heightened inflammation and inevitable harm to adjacent healthy tissues. To address these issues, we developed a nanosystem (M@PB) consisting of Prussian blue coated with tumor cell membrane for precise photothermal therapy (PTT) and subsequent reduction of inflammation.

Evaluation of endometrial receptivity in women with unexplained infertility by shear wave elastography.

Objectives: The endometrium of most unexplained infertility (UI) patients has been altered histologically. Shear wave elastography (SWE) is utilized to assess the signature of living tissue. This study aimed to explore the value of SWE in evaluating endometrial receptivity (ER) in UI patients.

[Difficulties and Countermeasures for Ortho Process Optimization in DR System].

Making an Ortho image is an important method to diagnose spinal and leg lesions in clinic. As the whole process requires multiple exposures in different positions, and it is very complicated and time consuming, it leads to low efficiency and it's hard to obtain ideal stitching result from image quality. The optimization of the workflow can not only reduce the workload of the operator, improve the work efficiency, but also improve the comfort of the patient in the process, finally to ensure the quality of the stitching image.

The effect of gel pads on the measurement of breast superficial lesions by shear wave elastography.

Objective: This study aimed to compare the repeatability and diagnostic efficiency of shear wave elastography (SWE) while using coupling gel and gel pads in the diagnosis of superficial breast lesions.

Methods: Two experienced sonographers, trained in SWE, used different methods to perform the maximum Young's modulus (Emax) measurement of the lesion while using coupling gel SWE and gel pad SWE at different time points. All 80 lesions were in the superficial layer of the breast.

Immersion ultrasonography improves the repeatability of cephalic vein diameter measurements for inexperienced operators.

Objective: To reduce the empirical dependence of ultrasound measurement of the cephalic vein diameter, improve the repeatability of measurements for inexperienced operators, and provide a new method for inexperienced operators.

Methods: Operators without ultrasound experience used contact ultrasound and immersion ultrasound to measure the diameter of the cephalic vein. The intraobserver and interobserver repeatability of measurements obtained the two methods were analyzed.

[Effect of low-dose focused ultrasound pre-irradiation versus microbubbles for enhancing high-intensity focused ultrasound ablation of VX hepatic tumor in rabbits].

Objective: To compare the effect of low-dose focused ultrasound pre-irradiation and microbubbles for enhancing the ablation effect of high intensity focused ultrasound (HIFU) on VX hepatic tumor in rabbits.

Methods: Fifty-five rabbits bearing VX hepatic tumor were randomly divided into low-dose pre-irradiation + HIFU ablation group, microbubbles+HIFU ablation group, and HIFU ablation group for corresponding treatments. The pathological changes in the tumors after low-dose irradiation, time for HIFU ablation, tumor volume with coagulative necrosis, energy efficiency factor (EEF), pathological changes in the ablated tumor, and sound channel of HIFU ablation were observed.
