... Abstract Many recent advances in the technology of radiotherapy have greatly increased the amount of image data that must be rapidly processed. With the increasing use of multimodality imaging for target definition in treatment planning, and daily image guidance in treatment delivery...

... Abstract Purpose: This study was aimed to demonstrate the accuracy of an image-guided targetlocalization system with 6D image fusion in a dedicated linear accelerator radiosurgeryunit, and compared to that with the 3D fusion. Materials and Methods: An anthropomorphicphantom implanted...

... Abstract Digital image analysis is applicable to clinical and non-clinical use cases in cytopathology. Various cytology samples, including smears, liquid-based preparations, and cell blocks, are suitable for image analysis. Cytopathology is one of the original fields in medicine where computer...

... acquisition. High-field MRI now allows direct visualization of target centers, and multiple modalities of intraoperative imaging provide visual confirmation of electrode location in relation to target structures [ 10 , 11 , 12 , 13 , 14 , 15 ]. The accuracy of DBS electrode placement using image guidance...

... Abstract Optical coherence tomography (OCT) angiography (OCT-A) is a transformative approach in imaging ocular vessels based on flow rather than simple reflectance intensity. It is therefore a functional extension of OCT that can be used to visualize microvasculature by detecting motion...

... Abstract The craniocervical junction is the most complex area of the spinal axis. Due to its complexity it is extremely vulnerable to injuries to the soft tissue stabilizing ligaments and membranous structures. Proper imaging in this area is an essential key to proper diagnosis directing...

... are under development, each of these still requires subjective human assessment. The existing approaches focus on assessing colour and texture features in clinical-scale images, such as those from dermoscopy and digital photography, and on structural or cellular characteristics in cellular-scale images...

... Abstract Two independent wavelengths of a near-infrared (NIR) fluorescent light probe are currently available in the clinical setting. These enable us to simultaneously see two different anatomies and/or functions. Many reports are available showing that NIR fluorescence imaging and merged...

... Abstract This chapter presents the physics of ultrasound, probe design, and some of the typicel artifacts present in pulmonological applications. Some of the techniques used for optimal imaging of chest anatomy are explained as well as the diagnostic questions that can be answered...

..., and verified using megavoltage radiographs of the treatment portal. Advances in imaging technologies have made it possible to image soft tissue volumes in the treatment setting. Real-time tracking is also possible using a variety of technologies, including fluoroscopic imaging and radiopaque markers implanted...

... Abstract Helical tomotherapy is a volumetric image-guided, fully dynamic, intensity-modulated radiation therapy (IMRT) delivery system. The daily use of its pretreatment megavoltage (MV) CT imaging for patient setup verification allows one to correct for interfraction setup error...

... Abstract Image-guided radiation therapy implies the use of a variety of imaging techniques in the treatment room to determine the location of target areas with the patient in the treatment position. This is particularly relevant for prostate cancer radiation therapy since the prostate gland can...

... Abstract Image guidance in pituitary surgery has evolved since diagnostic imaging of the sellarregion was first introduced at the turn of the 20th century. These advances have played a keyrole in the decrease in morbidity and mortality once associated with pituitary surgery. Thischapter details...
