美國和商標局已經給一家制造商的單光子發射掃描(SPECT)系統授予了一項，該系統掃描時間更短，可以用于臨床診斷。

掃描時間更短，是由于使用了清晰度恢復重建方法，例如UltraSPECT大光束重建(WBR)技術。這次正式認可允許UltraSPECT公司(Haifa, Israel)繼續供應先進的創新的核醫學(NM)系統。

使用傳統雙頭伽馬相機的NM心臟灌注核骨骼SPECT檢查時間在15～30分鐘之間。減少NM檢查的掃描時間同時維持圖像質量，是繁忙的NM檢查科室所迫切需要的。Xpress心臟和Xpress骨骼系統是UltraSPECT的兩種上市產品，掃描時間由于1個或多個因素而減少，而圖像質量沒用受到損害。

 
Patent Granted for Shorter SPECT Scan Times
 
The U.S. Patent and Trademark office has granted a patent to a manufacturer of single photon emission tomography (SPECT) systems for shorter scanning time and clinically diagnostic images.

These shorter scan times may be obtained by resolution recovery reconstruction methods such as the UltraSPECT patented Wide Beam Reconstruction (WBR) technology. This formal recognition allows UltraSPECT, Ltd. (Haifa, Israel) to continue to provide advanced and innovative nuclear medicine (NM) systems.

Scanning times of NM cardiac perfusion and bone SPECT studies range between 15 and 30 minutes in a traditional dual head gamma camera. Decreasing the scan time of NM procedures while maintaining image quality is a desirable characteristic for very busy NM clinics as well as for patient comfort. Xpress.cardiac and Xpress.bone, two of the systems that are marketed by UltraSPECT, demonstrate that scan times can be reduced by a factor of two or more with no degradation of image quality.
