Abstract

Quantitative Descriptive research with experimental opproach was done with x-ray machiine type UD150l-30E. The data of experiment was taken with made eight radiographs and the ESE measurement is conducted using TLD which layed on surface of abdomen phantom or at central point. Exposure was taken with eight times with eight variation of mAs. It is about 8,10,12,14,16,18,20 and 22 mAs with 80 kV. The result shown that there is a effetct of variation mAs to ESE and quality of radiographic anatomy image. Higher mAs result higher ESE and increase mAs about two interval reslut average value is 142 mR. Variation of mAs result variation of image quality. A good image quality with 19,1 cm part thickness resulted with use 18 mAs and 20 mAs with 80 kV. Optimum mAs with 80 kV in this research’s is 18 mAs.

Abstract

Technological evolution from conventional to digital in diagnostic imaging bring a change in the implementation of Quality Control (QC) of radiology. As a part of the Quality Assurance (QA), QC Radiology is implemented to determine the eligibility condition of the radiography equipment used for the radiological examinations. A Direct Digital Radiography (DDR) unit has been installed in Radiography Laboratory (Lab 3), School of Radiodiagnostic and Radiotherapy, the Health Polytechnic of Semarang since February 2013. However, routine performance tests of the equipment have never been performed. This study aimed to obtain baseline data by assessing the equipment parameters of the X-ray and the digital-DDR systems (illumination collimator; collimator accuracy; beam alignment; tube leakage; kVp accuracy; timer accuracy; mA linearity; reproducibility; HVL, and dark image; nonuniformity; noise; bad pixels; lag respectively). Accuracy and reproducibility of the DDR unit were measured following the procedure of Perka Bapeten No. 9-2011 (for X-ray System) and IEC 62220-1: 2003 (for digital system. Data were analyzed descriptively by QC-DR software. Results showed that X-rays system and digital system had overall good performance. Signal non-uniformity was found in the value of Local Signal to Noise Ratio (LSNRNU) and Global Signal to Noise Ratio (GSNRNU. Non-uniformity caused by the characteristics of the detector and the lack of correction in system performance. Signal correction software needed to be developed to reach signal uniformities. Spatial resolution and low contrast detectability testing also needed to be performed to ensure the ability of the DDR unit to produce image resolution and contrast picture of the object.

Abstract

This quantitative study was an experimental design. A total of 18 healthy male and female volunteers, with differnt BMI involved in the study by consecutive random sampling. An expert Radiologist evaluated all the 38 T2map images being studied. The arbitrary SI data were measured using one millimeter ROI of the machine measurement tools and the values of T2map were based on a fitted exponential decay calculation ?generated from the graphs developed by the Window excel. The mean differences amongst T2map values on the sagital plan femoro-tibial cartilage and coronal plan femoro-tibial (medial and lateral) were statistically tested using One-way Anova, and all the T2map images also graded by the radiologist following the OA the grading levels as published Internationally. In conclusion, an increased TE on the application of multi-spin echo sequence T2map, causing the calculated T2map values v? aried not only in the sagital area of t?he knee joint cartilage of the femoral and tibial but also in the coronal femoro-tibial (medial and lateral) for both the male and female healthy volunteer subjects, and different BMI category (under-weight, normal-weight, verweight). The values ?T2map within and between BMI group and among different gender showed statistically no difference (p-value > 0.05). The averaged T2map and its  tandard deviations have been used to define t?he T2map biomarkers (baseline T? 2map values) in each BMJ group subjects and between gender for both of the knee joint sagital and coronal planes despite the 1.5T MRI modality is not facilitated to commercial qMRI supporting software.

Abstract

High intensities of gastrointestinal tract may interfere to image quality of pancreatobilliary system that affects MRCP image degradation. The method of implementation of community service activities are divided into two activities : dissemination of material about improving the image optimization deployment training MRCP and use of oolong tea and herbal soy milk as an alternative oral negative contrast agent. Frameworks consist of input, process and output. Input as a potential target groups knowledge on the operation modalities of MRI and MRCP examination procedures. The process is in the form of training activities and the implementation of the use of oolong tea and herbal soy milk as an alternative to oral negative contrast agent on MRCP examination in hopes of generating output in the form of an increase in MRCP image optimization. Framework of solving problems through training implemented in the form of learning and mentoring using oolong tea and herbal soy milk as an alternative oral negative contrast agent MRCP, can produce contrast effect and image effect on the image enhancement MRCP optimization.

Abstract

Pijat bayi dapat diartikan sebagai sentuhan komunikasi yang nyaman antara ibu dan bayi. Pijat bayimerupakan ungkapan rasa kasih sayang antara orang tua dengan anak lewat sentuhan pada kulit. Stimulasimerupakan hal yang penting dalam tumbuh kembang anak. Anak yang mendapat stimulasi yang terarah danteratur akan lebih cepat berkembang dibandingkan dengan anak yang kurang atau tidak mendapat stimulasi.Sentuhan ibu juga akan direspon oleh bayi sebagai bentuk perlindungan, perhatian, dan ungkapan cinta.Tujuan dan manfaat pijat bayi sangat banyak, bagi bayi sendiri maupun ibu antara lain bermanfaat untukmeningkatkan kepercayaan diri, memudahkan orang tua mengenali bayinya, membina ikatan kasih sayangorang tua dan anak (bounding). Metode pengabdian dilakukan dengan cara ceramah dan simulasi pijat bayi.Promosi kesehatan dilakukan oleh dosen dan mahasiswa Jurusan Teknik Radiodiagnostik dan Radioterapi.Kegiatan bertempat di Balai Pertemuan Perum Sinar Waluyo RT 11 RW 01 Kelurahan Kedungmundu dengantema “Pijat Aman, Bayi Senang”. Pelaksanaannya pada saat kegiatan posyandu dan didukung narasumberdari Rumah Sakit Roemani Muhammadiyah Semarang. Peserta kegiatan sekitar 50 orang ibu dan bayi.Kegiatan dapat berjalan lancar, antusiasme warga dan respon yang positif. Diharapkan program tersebutdapat dilanjutkan di masa mendatang dengan topik yang berbeda sebagai wujud pengabdian masyarakat.

Abstract

Background: Radiograph of knee joint with Kellgren and Lawrence classification system is the gold standard for assessing knee osteoarthritis. However, these grades are still obstacles. It is sometimes not appropriate to assess the progress of osteoarthritis and very long time to see the results of such progress. Osteoarthritis diagnosis and classification have been relying on qualitative visual interpretation by a radiologist. Probably difficult to determine whether there OA in the knee or not. Image quantification of digital radiography is done by measuring the joint space width and tibio femoral angle of the knee joint using the ImageJ software, with body weight variance as one factor that could affect it. Aims: This research aims to get information of body weight effect on the measurement of the joint space width and tibio femoral angle of knee joint in OA detection. Methods: This is a cross-sectional study. Subjects were digital images of the knee joint anteroposterior (AP) projection using Computed Radiography (CR) from 21 respondents with specific criteria. Image is then quantified using ImageJ software to measure the joint space width and tibio femoral angle. Print out of examination visually evaluated by one radiologist to confirm the diagnosis of OA of the knee joint. Results: The value of the right knee joint space width lateral and medial (3.81 ± 1.18 and 2.42 ± 0.77), while the left lateral and medial (3.49 ± 1.11 and 2.69 ± 0.83). Tibio femoral angle range 168.44 to 178.39 with the average tibiofemoral angle right knee 175.18 ± 2.04 and 173.80 ± 2.44 left knee. Body weight has a significant correlation to the tibiofemoral angle of knee joint (p value < 0,03). Conclusion: The joint space width values that taken from digital quantificationcan be baseline data of respondents, especially for those respondents who had grade 2 or indicated osteoarthritis, to be observed or compared in the next examination.The tibio femoral angle can be addition information in relation with knee pain to detect osteoarthritis.
