"ABSTRAKPenelitian ini mengembangkan Computer Aided Diagnose (CAD) CT jantung pasiendewasa dengan menggunakan metode segmentasi deformable dan Frangi filter. Metode segmentasi deformable dan Frangi filter untuk mendapatkan posisi kalsifikasi di dalam maupun di luar arteri koroner. Setelah itu, kalsifikasi yang terdapat di dalam arteri koroner dihitung skor kalsium menggunakan metode skor Agatson dan dihitung persentase luasannya terhadap luaspembuluh darah untuk mengetahui korelasi antara skor kalsium, persentase penyempitan pembuluh darah dengan tingkat keparahan risiko penyakit jantung. Metode segmentasi deformable dan Frangi filter dapat menunjukan secara visual posisi kalsifikasi yang terdapat pada pembuluh darah arteri koroner untuk 4 cabang utama, yaitu left main (LM), left circumflex (LCx), left anterior descending (LAD), and right coronary arteries (RCA). Pada pengukuran persentase plak pada pembuluh darah, nilai persentase terendah adalah 20% sedangkan nilai persentase tertinggi adalah 75%. Tingkat risiko penyakit jantung koroner dapat diprediksi sebanding dengan nilai persentase plak pada pembuluh darah. Sementara itu, Perhitungan skor kalsium sesuai dengan hasil evaluasi dokter dalam penentuan stadium risiko penyakit jantung

ABSTRACTThis research developed Computer Aided Diagnose (CAD) CT heart of adult patients by using deformable segmentation method and Frangi filter. Method of deformable segmentation and Frangi filter to obtain the position of calcification inside and outside the coronary artery. Furthermore, calcification found in the coronary artery was calculated by calcium score using Agatson score method and calculated percentage of extent to blood vessel area to know correlation between calcium score, percentage of narrowing of bloodvessels with the severity of risk of heart disease. The deformable segmentation method and Frangi filter can show visually the position of calcification contained in coronary artery vein for 4 main branches, ie left main (LM), left circumflex (LCx), left anterior descending (LAD), and right coronary arteries (RCA ). In calculating the percentage of plaque on blood vessels, the lowest percentage value is 20% while the highest percentage value is 75%. Therisk of coronary heart disease is proportional to the percentage of plaque in blood vessels. Meanwhile, calcium score calculation is accordance with the results of the evaluation of the doctor in determining the stage of risk of heart disease"

"Dr. Vincent Di Maio and veteran crime writer Ron Franscell guide us behind the morgue doors to tell a fascinating life story through the cases that have made Di Maio famous--from the exhumation of assassin Lee Harvey Oswald to the complex issues in the shooting of Florida teenager Trayvon Martin. Beginning with his street-smart Italian origins in Brooklyn, the book spans 40 years of work and more than 9,000 autopsies, and Di Maio's eventual rise into the pantheon of forensic scientists."--Book jacket."In this clear-eyed, gritty, and enthralling narrative, Dr. Vincent Di Maio and veteran crime writer Ron Franscell guide us behind the morgue doors to tell a fascinating life story through the cases that have made Di Maio famous-from the exhumation of assassin Lee Harvey Oswald to the complex issues in the shooting of Florida teenager Trayvon Martin. Beginning with his street-smart Italian origins in Brooklyn, the book spans 40 years of work and more than 9,000 autopsies, and Di Maio's eventual rise into the pantheon of forensic scientists.

"Forensic professionals, often working through heavy caseloads, require quick and easy access to reliable sources of information to help interpret toxicology results. While several in-depth resources are available, they are often large, cumbersome, and contain more information than is needed. The Handbook of Forensic Toxicology for Medical Examiners is a concise handbook referencing the most common toxic substances and their levels of toxicity, making it an ideal text for quick confirmation in the field or in the lab." "The book begins by explaining the proper selection and submission of specimens for toxicological analysis. It describes the various types of specimens and identifies the cases for which these specimens would be most useful, providing instruction on proper collection. The author then explains the methodology involved in performing the specific tests." "The main section of the text consists of an alphabetical listing of nearly 300 toxic substances, including drugs of --abuse, poisons, prescription drugs, and over-the-counter medications. For each entry, the book provides the common brand names; classification; half life; volume of distribution; usual dosage; tables of toxicity in various samples, including blood, urine, and tissues; and other important information based on the extensive experience of the author. The text is heavily referenced with materials that are useful for preparation of courtroom testimony, and it contains supplemental appendices with information on acetylcholinesterase inhibitors, drugs that prolong the QT interval, pharmacogenetics, normal laboratory values, and conversion charts." "The busy forensic professional needs a concise handbook that provides critical information quickly without the need to wade through extraneous and inconsequential material. This volume offers an easy-to-use format that allows quick access to the most pertinent information, saving time and increasing accuracy." --Book Jacket."
