Optima NM/CT 640

Molecular imaging is unlike any other imaging technology. It enables the search for a different kind of discovery. The kind that reveals a deeply hidden truth that is reproducible evidence of what is seen and often not seen.

This type of discovery is known as a true discovery. It’s the type of discovery that inspires confidence. Confidence in the accuracy of what you see and in your ability to find disease sooner. And it’s what you require to take your diagnostic confidence to the next level.

To make true discovery part of your routine care, you need an economical system that can grow with your needs. A system with unrivaled performance for everyday use. That can provide high quality images at low doses. And can perform exams at a speed that drives efficiency.

Optima™ NM/CT 640 was designed to be this important first step. Its advanced technology builds off the potential of SPECT with the anatomical precision of CT. It gives you the image quality you need to make critical decisions at a low dose to patients. And because we understand the importance of making strong investment decisions, it was designed to deliver a low cost of ownership for your needs today and the ability to support your clinical SPECT/CT needs over time.

It’s the right balance of precision and performance, and the accessible starting point you need to start making true discovery part of your routine care.

Dose is an important piece of the patient experience for many imaging modalities, but it becomes doubly important for hybrid imaging. With key innovations in both SPECT and CT technology, Optima NM/CT 640 helps support reduction of dose all around.

In nuclear medicine, dose, image quality and time are closely linked. Historically, it’s been impossible to change one without having to adjust another. Evolution technology changes that relationship by applying a resolution recovery algorithm that models the collimator-detector response. The result permits up to half the scan time or up to half the dose while preserving an image quality similar to a full time or full dose scan1.

In addition, we designed a new CT specifically to meet your routine nuclear medicine hybrid imaging needs. Its detector is made of a ceramic material that enables fast optical photon conversion and an optimized detector geometry. And low mA X-ray tube output combined with fast rotation speeds result in exceptional image quality at lower doses compared to our first generation hybrid systems with slow rotating CTs.

Your system’s acquisition speed sets an important baseline that determines the number of patients you can reach every day. For facilities looking to extend their care to as many patients as possible, speed is important, but acquisition times are also inherently linked with image quality. To be effective, you need both the image quality to better understand each patient’s disease and the ability to reach more patients.

Optima NM/CT 640 allows you to dramatically reduce acquisition time without compromising image quality. Its advanced robotics and fast CT imaging significantly reduces the duration for a hybrid scan. The result is a reduction of about five minutes relative to an equivalent scan performed on Infinia Hawkeye 4².

For nuclear medicine, image quality is a leading priority. Now more than ever, radiologists and referring physicians are looking for imaging technologies that can give them the diagnostic certainty they require to make important decisions about patient care.

Featuring a leap forward in detector design, the Elite NXT detector sets a new standard in image quality for SPECT. Its thin design and auto-body contouring minimize the distance between the patient and the detector for excellent resolution. And SPECT-optimized collimators combined with a high count rate enable extremely precise event detection.

CT rotations on previous hybrid SPECT/CT systems lasted up to 14 seconds long. This contributed to motion artifacts from patient breathing and other movement. Because Optima NM/CT 640’s CT gantry is independent of the SPECT gantry, it can complete a CT rotation in as fast as one second. This enables it to capture many images in a series of brief exposures for reduced motion artifacts. The result is greater image clarity and a more comfortable patient experience.

The applications you use to interpret and communicate molecular information are just as important as the tracers used to highlight that information and the technology used to capture it.

Quantitative applications allow you to prove what you see and, more importantly, prove what can’t be seen. They give you the assurance to determine the best course of treatment and the confidence to adapt treatment. They also give you the information to build a database of accurate results. Results that can be used to better inform the decisions you make for each patient and also, to inform the research that will develop more specific indications for disease.

¹In clinical practice, Evolution options^1a (Evolution for Bone, Evolution for Cardiac, Evolution for Bone Planar) and Evolution Toolkit^1b are recommended for use following consultation of a Nuclear Medicine physician, physicist and/or application specialist to determine the appropriate dose or scan time reduction to obtain diagnostic image quality for a particular clinical task, depending on the protocol adopted by the clinical site.

^1aEvolution Options - Evolution claims are supported by simulation of count statistics using default factory protocols and imaging of 99mTc based radiotracers with LEHR collimator on anthropomorphic phantom or realistic NCAT – SIMSET phantom followed by quantitative and qualitative images comparison.

^1bEvolution Toolkit - Evolution Toolkit claims are supported by simulation of full count statistics using lesion simulation phantom images based on various radiotracers and collimators and by showing that SPECT image quality reconstructed with Evolution Toolkit provide equivalent clinical information but have better signal-to-noise, contrast, and lesion resolution compared to the images reconstructed with FBP / OSEM.
