SPECT - PULSECDC™ Compact Digital Cardiac Camera

Ideal for clinics, hospitals and mobiles.

The chair reclines into a bed for imaging. Patients of any size will find the chair to be easy to get onto and off of —much easier than getting onto and off of a bed, especially if the patient is large or elderly. Once in the chair, under the control of the technologist, the patient will be reclined into a comfortable supine position. Overhead arm holds are optimally located to ensure the patient is relaxed during imaging and therefore has less of a tendency to move during to move during the actual image acquisition. Less movement results in a better and clearer diagnostic image.
The patient is always comfortable throughout the entire procedure. Removable side arm rests add to patient comfort. Imaging occurs in the supine position avoiding concerns related to seated or reclined-seated imaging. A supine imaging position corresponds to the most commonly used normal databases. Prone imaging is also possible.

With the best reliability:
Positron Corporation cameras average better than 99% uptime

Before we designed the Pulse CDC™, we talked to cardiologists, technologists and physicists. We talked to hospitals, clinic owners and office managers. We made sure we understood.

The Pulse CDC™ can fit into a room as small as 6 1/2 ft x 9 1/2 ft with room for the workstation, technologist and patient. The Pulse CDC™ may very well fit into your existing office, with little or no requirement for renovations. With slightly larger rooms it may also be possible for the room to double as an imaging suite as well as a patient exam room — you might not need to give up a room!

Maximum Patient Throughput with No Compromises - A Dedicated Dual Head
The Pulse CDC™ is a fixed 90° dedicated dual head cardiac camera. Patients can be imaged up to twice as fast as with single heads.


ALL DIGITAL Event Positioning - the Real Truth about Digital Cameras

The Pulse CDC™ has all digital architecture, not an analog foundation. Other cameras might claim to be digital but the true definition of digital is in the details. All cameras using photomultiplier tubes (PMTs) must first process the analog signal produced by the PMTs. Truly digital cameras will digitize this signal at the earliest possible stage, and before summing of signals from multiple PMTs occurs.

Positron Corporation cameras have one analog digital converter (ADC) for each PMT. This provides individual signal processing and digitization for each PMT. All processing past the PMT pre-amplifier stage is done digitally for each signal including: sampling, integration, gain control, pedestal subtraction and
event positioning calculations. In the end the signal to noise ratio is better, which in turn results in a better final image.

The Pulse CDC™ provides ALL DIGITAL event positioning directly from each PMT. With some other cameras this process is not digital at each PMT. Rather, individual signals are summed and then the analog sum is digitized later in the process. This means that the benefits of digital technology cannot be applied to individual signals but only to the group sum. A true digital approach applies digital technology to each signal, from each PMT, and thereby results in digital event positioning. A true digital approach results in more precise event positioning, more accurate data and better image quality. Not all current model cameras do this. You should ask!


Because Specs Matter the Most…When Deciding Which Camera to Buy
When you buy a computer, sound system or even an electronic organizer, comparing the specs matters. It matters because the best product has the best specs. It’s exactly the same with gamma cameras.

The Pulse CDC™ has many of the best specs and performance parameters in the industry:

• intrinsic spatial resolution 2.9mm F.W.H.M.
  
  
• uniformity +/-2.0% integral +/-1.5% differential
  
  
• large FOV: 15x10.2 inches, no clipping of hearts
  
  
• energy resolution 9.0%
  
  
• center of rotation better than 0.5mm
  
  
• accommodates the largest patients: 450lbs bed capacity
  
• the best collimators…and more (Full spec sheet available upon request.)
  

At your request, Positron Corporation can provide you with a document that technically compares the Pulse CDC™ to other similar models of cardiac cameras.
As a physician, technologist, clinical office manager, physicist, medical executive or as an individual involved in purchasing a gamma camera you should request this document because:

The decision to purchase a gamma camera could have implications for a decade or more. The most important factors affecting the decision are technical specifications, reliability and price. Evaluation of one brand of camera versus another cannot be accurately completed within a matter of minutes. Investing the time to accurately compare the specifications may very well help you make the right decision for the next decade. It may also save you tens of thousands of dollars now, may reduce your annual service costs and may increase your annual uptime (and patient throughput) year in and year out.

You Should Know!
About how PMT’s are Powered A photomultiplier tube (PMT) can be powered by either positive or negative high voltage. PMT manufacturers recommend that gamma cameras not use negative high voltage because tube life can be reduced and tubes can become less reliable — long term service costs may increase. If a tube goes down, it is a difficult and time consuming repair that results in camera downtime — patients can’t be imaged. Additionally, negative high voltage can result in noise and degradation of image quality. Some gamma cameras do power PMTs with negative high voltage. You should ask! Positron Corporation powers PMTs with positive high voltage. Tube life is extended, camera downtime is reduced, service costs are decreased and image quality is improved.

Be sure to ask Positron Corporation for a technical comparison.
"I found the comparison to be the most detailed I have seen, a really thorough job. And, they were fair."


A Chair and a Bed, the Best of Both
Patients of any size will find the chair to be easy to get onto and off of — much easier than getting onto and off of a bed, especially if the patient is large or elderly. Once in the chair, under the control of the technologist, the patient will be reclined into a comfortable supine position (prone also possible). Overhead arm holds are optimally located to ensure the patient is relaxed during imaging and therefore has less of a tendency to move during the actual image acquisition. Less movement results in a better and clearer diagnostic image. Optional arm rests on each side of the chair add to patient comfort. Arm rests have an easy-on-off design to accommodate patient transfers from either side of the chair.

Imaging occurs in the supine position avoiding some of the concerns related to seated or reclined-seated imaging. A supine imaging position corresponds to the most commonly used normal databases.

In imaging patients it is important for the camera head to be parallel to the patient as this helps ensure accurate reconstruction of the image. If patients are imaged in the seated position it can be more difficult to ensure that the camera head is parallel to the patient throughout all projections in the study because the patient may slouch. If this occurs reconstruction is less accurate. Imaging in the supine position makes it easier to keep the camera head parallel to the patient.
