The medical imaging industry is moving into an age where cost effectiveness and reducing undesirable side effects are important considerations in decision making. As a result, there has been a dip in the extent of interdisciplinary translations across imaging modalities. The focus is now on fine tuning current technology to meet requirements.
Developments in MRI equipment are concentrated on designing stronger magnets or reducing the cost of achieving higher resolution. Others are attempts to develop advanced multichannel radio frequency (RF) coils. Innovations in X-ray imaging are mainly concentrated on the CT scan modality as it has become indispensible in most hospital settings.
Development of advanced transducers has captured more interest than research in any other component of the ultrasound machine. Replacement of traditional lead zirconate titanate (PZT) based transducers with capacitive micromachined ultrasonic transducers (cMUTs) is among the most popular solutions proposed.
Innovations in PET and SPECT closely follow developments in particle physics. The majority of the innovations witnessed in recent years are related to the design of detectors with improved gamma sensing properties. Among the intrapatient image co-registration modalities, PET/CT and SPECT/CT are the most commonly used multi-modal imaging techniques.
