Gamma imaging, a cornerstone of nuclear medicine, traditionally relies on large, stationary cameras. This limits patient access and restricts the technique to specialized departments. However, a new device, Seracam, is challenging the status quo.
Seracam is a compact, portable gamma camera designed for small-organ imaging. Its dimensions – just 15 cm in diameter and 24 cm long – and lightweight design (5 kg) enable its use in various clinical settings, from outpatient clinics to operating theaters.
At the heart of Seracam is a CsI(Tl) crystal scintillator that converts gamma rays into visible light. This light is captured by a high-resolution detector and analyzed to produce real-time images. A unique feature is the ability to switch between different pinhole collimators quickly, optimizing image resolution and sensitivity based on clinical need.
Beyond gamma detection, Seracam incorporates optical imaging, overlaying anatomical information with the gamma data. This hybrid approach provides valuable context for interpreting the images.
Initial tests have demonstrated Seracam’s capability for thyroid imaging and gastric emptying studies, with results comparable to larger, conventional systems. Its portability and versatility open up new possibilities for gamma imaging, such as real-time monitoring during surgery and expanded access for patients.
Seracam represents a significant advancement in gamma imaging technology. Its potential to transform clinical practice is immense, and future developments promise to expand the applications of this versatile device further.
