NucLear MAC
A high-performance computer system for nuclear medicine

UNRIVALED POWER, CLINICAL UTILITY, USER FRIENDLINESS, EXPANDABILITY & ECONOMY

Scientific Imaging's NucLear Mas has been among the world's best-selling nuclear medicine computers. Since 1990, Scientific Imaging has sold over 2,000 NucLear Mac acquisition and processing computers.* Scientific Imaging continues support and development of the NucLear Mac product line.

NucLear Mac runs in native-mode on Macintosh and MacOS-based computers. This provides for top performance on the latest Intel-based Mac computers. In addition, the use of the Macintosh platform avoids the planned obsolescence of dedicated systems. NucLear Mac users can immediately benefit from faster computers, more advanced peripherals and operating system improvements as they become available.

NucLear Mac is available in two configurations, Acquisition and Remote. The Acquisition system consists of software, one data-acquisition board and an interface assembly. The board and software let you:

  • Acquire data directly from gamma cameras and store the results
  • Display the data as high resolution gray-scale or color images
  • Perform clinical processing of the data and store the results
  • Share data with other MacOS programs, such as word processors, spreadsheets, and graphics applications

In addition, the use of MacOS makes it simple and inexpensive for you to:

  • Archive the data to a variety of media
  • Print the data and results of processing to hard copy
  • Transmit the data locally or over long distances
  • Share data with foreign systems using NucLear Mac's extensive import/export capabilities

The Remote system consists of software and a software key. Except for data acquisition, the Remote system's software functions identically to that of the Acquisition system.

Answers to Frequently Asked Questions

What Computers Can I Use? Any of the Macintosh or MacOS-compatible computers that have at least one free PCIe slot can be used for the Acquisition system. Any Macintosh or MacOS-compatible computer with a USB port can be used for a Remote system. The main difference between the systems will be in processing speed.

How Does My Gamma Camera Connect to the NucLear Mac? The connection is quite simple using the standard X, Y, and Z cables from all gamma cameras with analog outputs. The cables are plugged into the NucLear Mac interface box, which connects to the acquisition board. The software is configured for the voltage of the particular camera, and the system is ready to go. Assuming the gamma camera is functioning properly, the installation can be performed in 5 or 10 minutes.

How Good is the Data Acquisition? The NucLear Mac uses state-of-the-art 16-bit analog-to-digital conversion for the gamma camera signal digitization. Single images, sequential images, dynamic time series images, gated images, SPECT images, and gated-SPECT images can be acquired. Count rates of up to 300,000 counts per second can be handled and images up to 1024 x 1024 pixels can be generated. For time series and gated images, 1/1000 second timing is used. Compare these specifications to expensive, dedicated systems and you'll find little if any difference. In fact, the NucLear Mac outperforms most dedicated systems.

What About Simultaneous Acquisition and Processing? Of course! NucLear Mac can process data from one study while another study is being acquired. There is little loss in processing speed at typical count rates and no loss in data acquisition speed.

What Types of Monitors Are Used? Because NucLear Mac is completely Macintosh-compatible, you can choose the type of monitor that best suits your needs. Of course, all monitors have the well known clarity of the Macintosh computer line, differing only in size and resolution. Most monitors have a minimum resolution of 1024 x 768 pixels, which is fine for many applications, while monitors up to 30 inches with 2560 x 1600 pixels can be added if desired. In fact, you can use up to five monitors on a single computer and easily move images between them.

Is There Much Clinical Software Available?NucLear Mac supports all basic nuclear medicine processing including region-of-interest analysis, activity vs. time curves, curve math, image subtraction, split function determination, renal function by plasma samples or image analysis, cardiac ejection fraction analysis by first pass or with EKG gate, shunt quantification by gamma variant fitting, circumferential thallium quantification, SPECT processing, bull's-eye plotting, etc. In addition, a sophisticated programming interface allows users to write their own routines without any Macintosh-specific knowledge. Alternatively, NucLear Mac's comprehensive macro language can be used to execute many basic commands in sequence.

What About Sales and Service? NucLear Mac can be purchased directly from Scientific Imaging or from regional sales and service representatives. Thus the user can balance the system cost with the desired level of service. In any event, the price of the NucLear Mac is far less than other full-function nuclear medicine computers. Also, the user can expand the capability of the system by adding standard monitors, printers, etc.

What Hard Copy Is Available? Because NucLear Mac supports standard image formats such as PICT and TIFF, a wide variety of devices can be used for hard copy including standard video formatters, as well as film, laser, gray-scale, and color printers.

How About Networking? All Macintosh computers come with built-in Ethernet networking hardware and support TCP/IP communications protocols. The Apple System Software also includes easy-to-use file-sharing software. Transferring studies is a breeze. It doens't matter whether the other system is across the room or around the world. The other system doesn't even need to be a Macintosh.

Is Telecommunication Supported? Image data can be remotely transmitted for both display and processing at approximately 5600 pixels per second using standard 56k baud modems. Much higher transfer rates can be achieved over the Internet.
