Abstract

Magnetic Resonance Imaging (MRI) Brain examinations often encounter uncooperative patients, necessitating rapid scanning techniques that yield optimal results. To address this challenge, advanced technologies such as deep learning can be leveraged to accelerate scan time, reduce noise, and enhance image precision. This study aims to evaluate the disparity in MRI Brain image quality with and without deep learning in tumor cases to achieve superior diagnostic imaging. Employing a quantitative experimental approach, this research analyzed a sample of 30 patients collected from January to February 2025. Three Radiologist Specialists assessed the images using a questionnaire based on the Visual Grading Analysis (VGA) method. The obtained responses were statistically examined through Cohen’s Kappa consistency test and Wilcoxon Signed-Rank Test. Findings revealed a statistically significant difference in image information between deep learning-assisted and conventional MRI scans. In T2 TSE sequences, deep learning reconstruction demonstrated superior anatomical visualization of the Gray Matter, White Matter, Lateral Ventricles, Basal Ganglia, and Parafalx Cerebri. However, in brain tumor pathology visualization, conventional MRI exhibited sharper and more distinct tumor delineation. Although deep learning-enhanced T2 TSE sequences reduced scan duration and improved overall image quality, they provided suboptimal diagnostic information in tumor cases.

Abstract

Background: Conventional ultrasound (USG) gel was generally based on carbomer 940, which was relatively expensive, difficult to access in some areas, and not environmentally friendly due to its non-biodegradable nature. This study aims to evaluate the potential of salacca leaf sap as an alternative material for a more affordable, easily obtainable, and environmentally friendly natural ultrasound gel.Methods: A quantitative experimental study was conducted on 30 adult patients. Each subject underwent two liver ultrasound examinations using carbomer 940 gel and gel from salacca leaf sap. Image assessment was conducted by three radiology specialists using the visual grading method on the parameters of parenchyma, portal vein, nodules, and artifacts. Data were analyzed using the Wilcoxon test and Cohen's Kappa test to measure inter-rater agreement.Results: The research results indicate that there is no statistically significant difference between the ultrasound images using factory gel and salacca leaf sap gel (p 0.05). All image parameters, such as parenchymal homogeneity, visualization of the portal vein, and minimal artifacts, appeared equivalent in both types of gel.Conclusions: Salacca leaf sap shows physical characteristics that support ultrasonic wave transmission and is capable of producing liver ultrasound images comparable to commercial gel. With local availability, low cost, and environmentally friendly properties, this material has the potential to be a viable alternative to ultrasound gel that can be further developed for clinical practice and areas with limited access.

Abstract

The advancement of wearable technology has enabled commercial smartwatches to monitor vital health parameters such as blood oxygen saturation (SpO₂) and heart rate (BPM). This study aimed to evaluate the accuracy of SpO₂ and BPM readings from three commercial smartwatches: Realme C2 Pro, Oraimo 2 Plus OSW-32N, and Haylou LS02 Pro by comparing them to a standard medical-grade oximeter (Beurer PO40). A total of 34 participants were recruited, representing a range of skin tones identified using the Fitzpatrick Skin Type Scale (Types I–V). Statistical analyses, including Pearson’s correlation and Bland-Altman plots, were used to assess the relationship and agreement between devices. Results showed that the Realme C2 Pro provided the highest accuracy, with 99.58% for SpO₂ and 98.515% for BPM, while the Haylou LS02 Pro showed the lowest accuracy at 99.24% for SpO₂ and 97.29% for BPM. Bland-Altman analysis revealed small biases and narrow limits of agreement, indicating that the smartwatches produced readings closely aligned with those of the medical device. Despite minor discrepancies, all smartwatches demonstrated strong potential for health monitoring applications. The discussion highlights factors influencing measurement accuracy, including sensor quality, algorithm performance, and user-specific variables such as skin tone. These findings support the role of smartwatches as accessible tools for early health detection and continuous monitoring. Although not intended to replace clinical instruments, properly optimized smartwatches can complement healthcare systems by enabling timely interventions and enhancing disease management.

Abstract

This study addresses the limitations of traditional stethoscopes, which are constrained by their single-user design, dependence on auditory acuity, and susceptibility to background noise. These limitations hinder collaborative learning and diagnostic accuracy, particularly in noisy environments or during infectious disease outbreaks. The aim of this work is to develop a low-cost, speaker-output digital stethoscope that enables multiple users to simultaneously listen to heart sounds, improving both clinical training and infection control. The main contribution of this study is the integration of a conventional analog stethoscope with a high-sensitivity microphone preamplifier, an external speaker, and digital signal processing (DSP) algorithms. This configuration allows the amplification and filtering of heart sounds, enabling group auscultation without the need for earpieces. The device casing is constructed from High-Pressure Laminate (HPL) sheets and multiplex wood panels, while acoustic foam is used to reduce noise interference.  Heart sounds are captured via a microphone, amplified, and processed using Fast Fourier Transform (FFT) and band-pass filtering (20–150 Hz) to isolate the key frequencies. The system was tested in a quiet clinical setting, and the resulting audio was analyzed for clarity and frequency spectrum. The prototype successfully captured heart sounds, with a dominant spectral peak around 97 Hz, consistent with the primary frequency of heartbeats. It also clearly identified the first (S1) and second (S2) heart sounds. However, ambient noise affected sound clarity, indicating the need for further noise reduction. Despite this limitation, the device successfully enabled group auscultation. In conclusion, the speaker-output stethoscope offers an affordable and effective alternative to traditional auscultation, enhancing medical training and improving infection control. Although noise reduction requires further refinement, the system demonstrates strong potential for application in clinical and educational settings, particularly in low-resource environments

Abstract

Nowadays, health care has turned out to be more technology-oriented. Today's technology is demanded to be practical and easy to use. Based on data, the number of uses of mobile devices based on the Android operating system has increased significantly. The open-source nature of android helps in programming applications easily according to user requirements. A syringe pump is a medical device that functions to enter the medicinal fluid into the patient's body at a certain dose and time automatically in mL/hour. The syringe pump is generally equipped with an alarm. Alarms have a vital function to provide information to nurses or doctors who are on duty. Medical officers cannot hear alarms if they are outside the patient monitoring room. This paper aims to design a syringe pump that is equipped with a NodeMCU8266 WiFi module to provide notifications via a smartphone so that nurses or doctors can know the alarm even though they are outside the patient monitoring room. So, this is expected can improve patient safety. In addition, this paper also aims to verify the size of the syringe against the drug flow rate. Based on the test results, the syringe pump can control the drug flow rate with a sensor accuracy of 0.0217 and an error rate of 0.6% at a target volume of 5mL. The syringe pump can also send alarm notifications to smartphones in real-time.

Abstract

Scattered radiation exposure during radiology procedures can reach the head and eye lenses of personnel, requiring eye protection with good radiation attenuation capabilities without compromising comfort. Conventional lead-based radiation protection materials have high density, making them heavy and less ergonomic for long-term use. This study aims to evaluate the X-ray attenuation capability of a transparent epoxy resin–bismuth oxide (Bi₂O₃) composite as a candidate optical shielding material for radiation glasses based on the Half Value Layer (HVL) parameter. The composite was made using epoxy resin as a matrix and Bi₂O₃ as a high atomic number filler, with a mass ratio of 5:1 and a thickness of 0.5 mm and 1.0 mm. Measurements were performed using a diagnostic X-ray machine at voltages of 40 kV and 45 kV with an ionization dosimeter detector. The HVL value was calculated based on the linear attenuation coefficient (μ), and the data were analyzed using the Shapiro–Wilk normality test and Spearman's correlation. The results showed that an increase in composite thickness resulted in an increase in the HVL value, and there was a significant positive correlation between thickness and HVL (r = 0.681; p < 0.01). The epoxy resin–Bi₂O₃ composite showed effective attenuation at thin thicknesses with optical transparency characteristics, making it a potential lead-free optical shielding material for radiation glasses. These findings demonstrate that Bi₂O₃--epoxy resin composites are promising candidates for developing lightweight, transparent, and effective radiation protective eyewear.

Abstract

Fetal Doppler is a diagnostic tool to detect fetal heart rate in BPM (beats per minute). Like other medical devices, it must be calibrated periodically by a health facility testing center, as stated in the Regulation of the Minister of Health of Indonesia Number 54 of 2015 article 4 paragraph 1. Article 8 paragraph 1 explains that testing or calibration of medical devices is carried out periodically at least once a year. In addition, testing must be carried out after repairs to medical devices as stated in SNI IEC 62353 of 2014. In addition to testing and calibration, medical devices need to be maintained and tested for function. Therefore, a fetal doppler simulator is needed by medical device technicians to test the function of the fetal doppler. The innovation made on this device is that the simulator is connected to a smartphone with the aim of minimizing electronic components, eliminating settings with buttons and replacing them with Voice Control on the smartphone. This fetal doppler simulator is successfully designed well, it can simulate fetal heart rate from 60-240 BPM with error value of 0% at settings of 90,120,150,180, and 240 BPM. While at setting 60 BPM there is an error value of 1.6%. This simulator is suitable for use as a reference for fetal doppler function test because the error value is below the tolerance of ±5 for BPM on fetal Doppler.

Abstract

Cables in nurse call systems generally have considerable length and are distributed across multiple installation points, making them vulnerable to faults such as broken wires, loose connections, or continuity problems. These conditions can disrupt communication between patients and medical staff, potentially reducing the quality of healthcare services. Therefore, checking cable continuity before and after the installation process is a crucial step to ensure that each line is properly connected and that the nurse call system operates optimally and reliably. This study designs and tests a low-cost prototype device for checking the continuity of nurse call cables, consisting of two modules: Device A as a 9-volt power source and Device B as a two-line LED-based indicator. The novelty of this research lies in the use of a simple non-microcontroller circuit with direct visual indicators, specifically designed for on-site nurse call cable inspection as a practical alternative to conventional multimeters. The research method includes circuit design, prototype development, and field testing on cables with various length variations, followed by a functional comparison with conventional testing methods. The test results indicate that the device is capable of reliably detecting cable conditions through LED indicators that turn on or off during each test, with a high level of consistency. In addition, its low production cost and ease of use provide practical contributions for technicians involved in the installation and maintenance of nurse call systems, particularly in field conditions that require fast and efficient inspection.
