Nuclear medicine is an endoradiology that uses radioactive substances and records the radiation that emits from within the body in order to diagnose and treat the diseases. For the diagnosis radiopharmaceuticals are taken internally either orally or intravenously. External detectors also called as gamma cameras capture and then form images by the use of radiopharmaceuticals from its radiation emitted.

This technique is widely used as compared to conventional tomography because it can readily image both hard and soft tissues while conventional tomography is poor at imaging soft tissues.

Elastography is used for the diagnostic information of the tissue whether hard or soft. It is used to investigate cancerous tumours or diseases associated with liver. This modality uses magnetic resonance imaging ( MRI) or ultrasound to make an anatomical image and stiffness map for comparison. 

Pathology imaging mainly aims to image anatomic pathology to diagnose and improve the patients lives. This will enable greater access for Pathologists to know about the scanners for real time viewing of the image and the précised image will improve the clinical and medical imaging, reproducibility and research productivities. 

The term molecular imaging is originated from the field of radiopharmacology to understand the molecular pathways inside organisms in a noninvasive manner. It helps in the visualisation of the cellular function and follow up the molecular process in living organisms. This technique enables the diagnosis of diseases such as neurological, cardiovascular diseases and cancer. This technique uses biomarkers to help image particular targets or pathways. 

Various technologies are introduced to diagnose the diseases and form the images of internal aspect of the body such as mammographic imaging, cardiovascular imaging, neuroimaging, preclinical imaging and interventional imaging.

Cancer which is the abnormal growth of cells has the potential to spread to other parts of the body. The researchers are developing new therapies and with the help of imaging technologies, it is developing a way to restrict the growth of cells. Medical imaging aims in the management of patients with cancer. 

Its ability to faster imaging yield better information and the imaging technologies helps in the diagnosis and treatment of various diseases such as lung cancer, prostate cancer, breast cancer, heart diseases and so on.

The merging of imaging modalities such as PET/CT, PET/SPECT and PET/MRI helps in providing more full gamut of imaging scans with improved capacity to discriminate normal from abnormal tissues and produces co -registered images. 

The global radiology information system market has been segmented based on component, type, deployment mode, geography and end user. It analyses competitive developments, such as joint ventures, alliances, mergers & acquisitions in the global market.

Furthermore, the rising number of health related cases like age-related disorders and trauma patients has increased the patient flow and has generated the need of information systems globally. 

Medical Image Processing  meet challenges and provides an enduring bridge in the ever expanding field of medical imaging. It serves as an authoritative resource and self-study guide explaining sophisticated techniques of quantitative image analysis, focusing on medical applications. It emphasizes the conceptual framework of image analysis and the effective use of image processing tools.

Ophthalmic imaging is a highly specialized form of medical imaging dedicated to the study and treatment of disorders of the eye. It covers a wide range of scope of photographic services that incorporates many aspects of commercial and medical photography. But it is through the use of highly specialized equipment used to document parts of the eye like the cornea, iris, and retina, that ophthalmic photography takes on it's true identity.

The retina is the "film" of the eye. Images passing through the clear structures of the cornea and lens are focused there to give us our view of the world. Special instruments called fundus cameras, when used by skilled photographers, can document the condition of this miraculous anatomical structure.

Ophthalmic imaging has played an important role in the documentation and diagnosis of various ophthalmic diseases. Ocular photography is used to record medical conditions, track disease progression and create illustrations for publication and education. The primary role of ophthalmic imaging however, goes well beyond documentation in its ability to aid in the diagnosis of a broad range of eye conditions
