Technical Advances in Current PET and Hybrid Imaging Systems

The continuing efforts of investigators to achieve the best physical and clinical performances from PET (positron emission tomography) and related hybrid cameras (PET/CT and PET/MRI) have led to remarkable technical advances in hardware and software. Time of flight (TOF) information measurement, which has been enabled thanks to the invention of fast, heavy crystals and advances in fast light de...

Ultrasonic Imaging

The basic principles of ultrasonic B-mode imaging aresummarized. Tissue features that generate contrast andsystem features that control image quality are reviewed inthe context of breast cancer imaging. Approaches to signalmodeling, including B-mode and Doppler techniques, arereviewed to guide methodological design and clinical eval-uation. The article concludes with a b...

Advances in Ultrasonic Assessment of Acardiac Twin

The development of an acardiac anomaly, one of the most severe human malformations, is a rare complication unique to monochorionic multiple pregnancies. In this condition, the primary malformation is the lack of a well-defined cardiac structure in one twin (the acardiac twin), which is kept alive by its structurally normal co-twin (the pump twin). The final diagnosis for a twin pregnancy with a...
