There are variations in x-ray beam angulation applied in examining lumbosacral joint lateral projection, both theoretical and practical. According to Clark (1973) examination of lumbosacral joint lateral projection uses beam direction of 0 Â°, Ballinger (1999) stated that x-ray beam is directed 5 Âº to 8 Âº caudally and Bontrager (2001) ranging from 5 Âº to 10 Âº to the caudally. The purpose of this study is to investigate the influence of x-ray beam angulation to radiographic anatomical criteria and to find the most appropriate x-ray beam angulation to achieve good radiographic anatomical criteria conducted in examining lumbosacral joint lateral projections using x-ray beam angulation of 0 Âº, 5 Âº, 10 Âº and 15 Âº caudally. The study was experimental with observational method approach.Â Observation is done by examining lumbosacral joint lateral projections with the variations of x-ray beam angulations of 0 Âº, 5 Âº, 10 Âº and 15 Âº caudally. The data is collected by conducting tests, and spreading questionnaires (check list). There are 15 observers in spreading questionnaires.Â Radiographic results are recorded as experimental documents.Â Methods of data analysis used descriptive analysis by simple regression and crosstab data. Data are codified and categorized then. The results of this research showed that there are positive significant and correlation between x-ray beam angulation variations of 0Âº, 5Âº, 10Âº, 15Âº caudally to the radiographic anatomical criteria produced on examining lumbosacral joint lateral projection.Â It is indicated by p value = 0.016 (<0.05), means Ha is accepted and Ho is rejected. The best x-ray beam angulation is 15Âº caudally.Â This angulation can produce good radiographic anatomical criteria.

THE INFLUENCE OF PULSE GATING APLICATION ON IMAGE OF CAROTID ARTERIES ON MAGNETIC RESONANCE ANGIOGRAPHY EXAMINATION USE 0.3 TESLA MRI APPARTUS AT TELOGOREJO HOSPITAL IN SEMARANGMagmetic resonance angiography (MR Angiography) is a sequence of MRI examination to study blood vascular system with or without introduce of contrast agent. Carotid arteries, part of blood vascular system commonly studied by doing MRA exam. Time of Flight (TOF), one of the methods of MRA exam that can be perform blood vessels or flowing spin as a bright image, without introduce contrast agent into blood vessels. Pulse gating application on carotid arteries MR Angiography examÂ reduces cardiac pulsation effect, So the image looks better. The purpose of the research to findout the influence of pulse gating aplicationon on carotid arteries image of MRA exam use 0.3 Tesla MRI apparatus at Telogorejo hospital in Semarang. Type of the research is pre-experiment with descriptive methode. Data collected by doing MRA exam of extra cranial carotid arteries on a volunteer in Telogorejo hospital, with and without pulse gating application. Conspicuity of images appears by measuring Signal to Noise Ratio and Contrast to Noise Ratio on image of flowing spin of carotid arteries and supported by opinion of five Radiologists in Semarang. Data analysis use statistic procedure and descriptive methode. Measuring SNR use software of computer of MRI unit and CNR value obtained by reducing SNR value of flowing spin with SNR value of stationary spin. The result of the research shown that application of pulse gating influence the quality of image on MRA carotid arteries. Â Key word :Â Carotid arteries, pulse gating, image quality, 0.3 Tesla. Â

This research is conducted in Department of Radiology Dr. Kariadi Hospital Semarang.Â The purpose is to know the influence of kV variation to uniformity CT number using Somatom Emotion CT Scan Unit. The type of this research is experimental research using analytic study.Â The experiment is conducted by scanning water phantom 3 (three) times by using kV variations (80 kV, 110 kV, 130 kV). Three slices were made for every kV.Â CT Number Rate is measured using ROI software.Â ROI Width used is about 2-3 cm2 (Â± 200-300 pixels). The ROI located in the center scanning area and the surrounded area (clockwise) at 12, 3, 6 and 9. This research is conducted everyday for five days. The urgensi of this study is to ascertain uniformity CT number be in good condition, if its unstandart will difficult to differentiate attenuation coefficient to diagnosis a normaly or pathologis tissue. The result of measurement about CT number shown that the kV election at 80 kV, 110 kV and 130 kV the value of uniformity CT number is belowÂ 0Â±5 HU. The result of research is still in tolerance given by the manual operating book of Somatom Emotion CT Scan Unit.Â The book stated that the value of HU water is about 0 to Â±4.Â it means that HU value started from - 4 up to 4.Â It indicates that Somatom Emotion CT Scan Unit used in Department of Radiology Dr. Kariadi Hospital Semarang has good component in uniformity CT number according to standard. Interpretation result of hypothesis test based on correlation coefficient (r) is equal to 0,473. It is still in the range of 0,25 â¤ r < 0,5 which means the correlation is low. The value â 0,473 (negative) means that the correlation is contradictive. Where the increase of kV value will lead to decrease of noise (CT number fluctuation). It is also mean that uniformity CT number near to 0 (zero), which means the CT number is more uniform. The value of coefficient Determinance ( rÂ²) is 0,224 ( 22,4 %) which means the influence between the increase of kV value to uniformity CT number is equel to 22,4%, the rest Of 77,6% is influenced by the other factors.

STIKES Widya Husada Semarang menggunakan beberapa jalur penerimaan mahasiswa baru. Jalur tersebut diantaranya adalah jalur PMDK (Penerimaan Mahasiswa dengan Prestasi) dan jalur reguler yaitu dengan ujian on line dimana calon mahasiswa mengikuti seleksi melalui internet dengan mengisi soal-soal yang telah disediakan. Pada perjalanan perkuliahan terdapat mahasiswa yang baik prestasi akademik. Prestasi akademik merupakan perubahan dalam hal kecakapan tingkah laku, ataupun kemampuan yang dapat bertambah selama beberapa waktu dan tidak disebabkan proses pertumbuhan, tetapi adanya situasi belajar. Prestasi akademik ini utamanya dapat dilihat pada Indek Prestasi mahasiswa. Sebaliknya ada juga mahasiswa yang tidak baik prestasi akademiknya. Penelitian ini diarahkan untuk meneliti perbedaan prestasi akademik mahasiswa berdasarkan jalur masuk yang digunakan yaitu secara reguler atau melalui ujian online.Penelitian ini menggunakan rancangan penelitian analitik dengan pendekatan penelitian kuantitatif. Pendekatan kuantitatif merupakan penelitian analitik penjelasan (explanatory) dengan menggunakan desain cross sectional study, dimana variabel independent dan variabel dependent pada objek penelitian diukur secara simultan dalam waktu bersamaan. Desain penelitian tersebut dipilih untuk menganalisa hubungan independent (penerimaan mahasiswa baru metode on line dan jalur prestasi) dengan prestasi mahasiswa Prodi D III Teknik Rontgen STIKES Widya Husada Semarang.Hasil ujian on-line memiliki pengaruh positif dan signifikan terhadap prestasi mahasiswa. Hasil ujian on-line yang lebih baik akan meningkatkan prestasi mahasiswa. PMDK memiliki pengaruh positif dan signifikan terhadap prestasi mahasiswa.
