Journal Title：Photoacoustics

The aim of the open access Photoacoustics journal (PACS) is to publish original research and review contributions within the fast growing field of photoacoustics (optoacoustics) and thermoacoustics, which exploits optically and electromagnetically excited acoustical and thermal phenomena for visualization and characterization of a variety of materials and biological tissues, including living organisms. While some of the spectroscopic and photothermal applications have reached a mature state, many other research directions experience an explosive growth, in particular biomedical photoacoustics, which is currently considered the fastest growing bio-imaging modality. The wealth of investigated topics clearly indicates that this field has developed a broad range of tools for fundamental and applied research. The enormous recent progress is greatly supported by the advances in laser technologies, ultrasound detection approaches, development of inverse theory and fast reconstruction algorithms. This progress is also driven by a large number of unmet biological and medical needs that can be addressed by the unique contrast mechanisms available to photoacoustic (optoacoustic) methods. These include pre-clinical research and clinical imaging of vasculature, tissue and disease physiology, drug efficacy and treatment monitoring, optical anatomy and molecular imaging employing fluorochromes, chromophores and nanoparticles. Correspondingly applications span the entire range of biological and medical imaging including cancer, cardiovascular diseases, neuroimaging, ophthalmology or imaging in immunology, diabetes and obesity, cell trafficking application and a multitude of other biological functions. The multi-disciplinarily nature of photoacoustics and thermoacoustics is also evinced by the growing contribution from chemistry and nanotechnology where a multitude of novel contrast materials and agents have been constantly developed, from nanoparticles and organic dyes, to targeted agents and genetically expressed markers.

开放获取光声学期刊 (PACS) 的目的是在快速发展的光声学（光声学）和热声学领域发表原创研究和评论贡献，该领域利用光学和电磁激发的声学和热现象来可视化和表征各种材料和生物组织，包括活的有机体。虽然一些光谱和光热应用已经达到成熟状态，但许多其他研究方向经历了爆炸式增长，特别是生物医学光声学，它目前被认为是增长最快的生物成像方式。丰富的研究主题清楚地表明，该领域已经为基础和应用研究开发了广泛的工具。激光技术、超声检测方法、逆理论的发展和快速重建算法的进步极大地支持了最近的巨大进步。这一进展也受到大量未满足的生物和医学需求的推动，这些需求可以通过光声（光声）方法可用的独特对比机制来解决。这些包括脉管系统、组织和疾病生理学、药物疗效和治疗监测、光学解剖学和使用荧光染料、生色团和纳米粒子的分子成像的临床前研究和临床成像。相应的应用涵盖了整个生物和医学成像范围，包括癌症、心血管疾病、神经成像、眼科或免疫学成像、糖尿病和肥胖症、细胞运输应用以及许多其他生物功能。光声学和热声学的多学科性质也体现在化学和纳米技术的日益增长的贡献中，从纳米粒子和有机染料到靶向剂和基因表达标记物，大量新型对比材料和试剂不断被开发出来。

名词解释：
中科院分区也叫中科院JCR分区，基础版分为13个大类学科，然后按照各类期刊影响因子分别将每个类别分为四个区， 影响因子5%为1区，6%-20%为2区，21%-50%为3区，其余为4区。

大类学科	小类学科	分区
工程技术	INSTRUMENTS & INSTRUMENTATION 仪器仪表 ENGINEERING, BIOMEDICAL 工程：生物医学 RADIOLOGY, NUCLEAR MEDICINE & MEDICAL IMAGING 核医学	1区

名词解释：
JCR没有设置大类，只分为176个具体学科，按当期（1年）的影响因子进行分区；JCR是按照“平均主义”思想， 根据刊物IF的高至低平均划分4个区，每个区含有该领域总量25%的期刊。中科院的分区如同社会阶层的金字塔结构，1区只有5%的顶级期刊， 2~4区期刊数量也逐层增加,所以中科院的1区和2区杂志很少，杂志质量相对也高，基本都是本领域的顶级期刊。
