تقنية تصوير تستخدم أجهزة الأشعة السينية والقدرات الحاسوبية لتوليد صور تفصيلية للعظام والأنسجة الطرية داخل جسم الإنسان. يلتقط جهاز التصوير الطبقي المحوري سلسلة من صور الأشعة السينية المأخوذة من زوايا مختلفة حول الجسم بالاعتماد على شعاع دوّار داخله، ويستخدم تقنيات معالجة الصورة لدمجها وإنشاء صورة مقطعية (شرائح) للعظام أو الأوعية الدموية وغيرها. وبذلك يقدم صوراً تحتوي معلومات أكثر تفصيلاً من تلك التي تقدمها صور الأشعة السينية بمفردها.
يقدم التصوير الطبقي المحوري صوراً تفصيلية للجسم بما في ذلك الأعضاء الداخلية والأوعية الدموية والعظام، ويستخدم في الحالات التالية:
